Harry Potter - The Philosopher's stone

After arriving at the Hogwarts castle, after McGonagall explained there are four different houses; "Gryffindor, Hufflepuff, Ravenclaw and Slytherin." She went to inform Dumbledore that all of them arrived safely.

While the first-years are waiting outside the Great Hall, a pale boy with slicked-back blond hair approaches Harry, accompanied by Crabbe and Goyle. He looks Harry over and says, “So it’s true, then. What they were saying on the train?”

Harry asks what people are saying. The boy introduces himself as Draco Malfoy. Ron storted and Draco recognize him as a Weasely. He then says that some wizarding families are better than others and implies that Harry should be careful about who he associates with at Hogwarts, glancing at Ron briefly.

Draco holds out his hand and offers to be Harry’s friend. He makes it clear that he doesn't approve of Ron Weasley, calling him the wrong sort and suggesting Harry should stay away from people like him.

Harry looks at Draco’s outstretched hand but refuses to take it. He tells Draco, “I think I can tell the wrong sort for myself, thanks.”

Draco's expression changes, clearly offended. He turns away and leaves with Crabbe and Goyle. Harry remains with Ron and the other first-years.

This is Harry and Draco’s first real interaction, and it immediately establishes their rivalry: Draco tries to judge Harry by his reputation and blood status, while Harry rejects Draco’s attitude and chooses to stay with Ron.

Harry is sitting in a compartment when Ron enters and asks if the seats are taken. Harry says no, and Ron sits down. They introduce themselves, and Ron soon realizes that Harry is Harry Potter. He asks about Harry’s scar, and Harry explains that he doesn’t remember how he got it.

Ron tells Harry about his family and explains that he has several brothers, some of whom already attend Hogwarts. Harry admits that he knows very little about the wizarding world because he was raised by his aunt and uncle.

Ron then shows Harry his pet rat, Scabbers. He explains that he is trying to turn him yellow. Ron takes out his wand and prepares to try the spell while Scabbers is busy poking his head into a box, trying to eat the remaining candy.

Before Ron can properly demonstrate the spell, Hermione enters the compartment. She watches Ron and asks, “Oh, you’re doing magic? Let’s see, then.”

Ron points his wand at Scabbers and attempts the spell: “Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow!” Instead of turning yellow, Scabbers causes the box he is eating from to explode. Ron immediately looks at Harry, while Hermione comments, “Is that really a spell? Well, it’s not very good, then.”

Hermione sits down opposite Harry and introduces herself as Hermione Granger. She explains that she is looking for Neville Longbottom’s missing toad, Trevor. She then notices Harry’s glasses and asks to see them. Taking out her wand, she casts “Oculus Reparo,” repairing Harry’s glasses instantly.

Harry and Ron are impressed. Hermione proudly explains that she has already learned several spells from her books, making it clear that she is very knowledgeable about magic. She then leaves to continue searching for Neville’s toad, leaving Harry and Ron behind.

Harry meets Ron aboard the Hogwarts Express. Harry walks through the crowded train looking for a compartment and finds Ron Weasley sitting alone. Harry asks if the seat is free, and Ron tells him it is. Harry sits down, and they introduce themselves.

Ron soon notices Harry’s scar and realizes who he is. “Are you really Harry Potter?” he asks. Harry confirms it, and Ron is amazed. Ron asks how Harry got the scar, but Harry admits he doesn’t remember. Ron then explains that he comes from a wizarding family and that his brothers are also going to Hogwarts. Harry reveals that he grew up with his aunt and uncle and knows almost nothing about the wizarding world.

Ron shows Harry his pet rat, Scabbers, and explains that his older brother Percy gave him to him. Ron says he is trying to turn Scabbers yellow. He points his wand at the rat and recites, “Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow!” Nothing happens. Ron tries again while Harry watches.

The trolley then comes by, and Harry buys a large amount of sweets. He offers some to Ron, who is surprised by how much Harry has. They eat Chocolate Frogs and Bertie Bott’s Every Flavour Beans. Ron explains that the beans can taste like anything, including disgusting flavours.

While they are eating, Ron talks about Hogwarts and his family, while Harry asks questions about the wizarding world. The two quickly become comfortable with each other. Before long, Ron is once again trying to get Scabbers to turn yellow when Hermione enters the compartment looking for Neville’s missing toad, Trevor.

Their first meeting is simple but important: Harry, who has never had a real friend in the wizarding world, meets Ron, and the two quickly form a friendship over conversation, sweets, and Ron’s completely unsuccessful attempt to perform magic on his rat.

When the Hogwarts Express arrives, Hagrid gathers the first-years and leads them to the boats. They cross the lake toward Hogwarts, with Harry staring in amazement at the enormous castle above them.

After reaching the castle, the first-years are left waiting in a chamber before entering the Great Hall. While they wait, Draco Malfoy approaches Harry with Crabbe and Goyle. He begins, “So, it’s true then,” referring to Harry really being Harry Potter. Draco introduces himself and says he can tell Harry which families are worth knowing. He then offers his friendship, but warns Harry that he shouldn’t associate with the “wrong sort,” clearly meaning Ron and his family.

Draco holds out his hand, expecting Harry to accept. Harry refuses and tells him he can tell the wrong sort for himself. Draco is unimpressed and leaves with Crabbe and Goyle.

Professor McGonagall then arrives and leads the students into the Great Hall. They stand before the four house tables while the Sorting Hat is placed on a stool. The Hat sings its song, explaining the qualities of Gryffindor, Hufflepuff, Ravenclaw, and Slytherin.

The Sorting begins. Hermione is called first among the main trio and is sorted into Gryffindor. Ron follows and is also placed in Gryffindor. When Harry’s name is called, he sits beneath the Sorting Hat. After a tense pause, the Hat shouts, “GRYFFINDOR!” Harry joins Ron and Hermione at the Gryffindor table, while Draco watches from the Slytherin table.

On the Hogwarts Express, Harry walks along the crowded train looking for a compartment. He finds Ron Weasley sitting alone and asks if the seat is free. Ron introduces himself and explains that his brothers Fred and George are also on the train. When Ron notices Harry’s scar, he realizes who he is and asks, “Are you really Harry Potter?” Harry confirms it, and Ron is amazed.

They begin talking. Ron explains that he comes from a wizarding family, while Harry admits he knows very little about magic because he grew up with his aunt and uncle. Ron then shows Harry his pet rat, Scabbers, and explains that he is trying to turn him yellow. He attempts the spell, “Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow!” but nothing happens. Ron keeps trying while Harry watches.

Harry opens the sweets he bought from the trolley and shares them with Ron, including Chocolate Frogs and Bertie Bott’s Every Flavour Beans. They eat and talk, with Ron warning Harry that the beans can taste like anything.

While Ron is still trying to turn Scabbers yellow, the compartment door opens. A bushy-haired girl, Hermione Granger, appears. She introduces herself and explains that she is looking for Neville Longbottom’s missing toad, Trevor. She immediately recognizes Harry and is excited to meet him.

Hermione notices Ron performing the spell and asks what he is doing. Ron says he is trying to turn his rat yellow. Hermione points out that the spell isn't working and confidently mentions that she has read all the books she was given. She then leaves to continue searching for Trevor, leaving Harry and Ron behind.

Harry Potter and Ron Weasley become best friends almost immediately in the first film, and their friendship is built on trust, loyalty, and feeling understood.
Harry is quiet, humble, and completely new to the wizarding world. Ron, having grown up in a wizarding family, happily explains things Harry doesn't know without making him feel stupid. In return, Harry treats Ron as an equal instead of comparing him to his talented older brothers, something Ron deeply appreciates.
Their personalities complement each other:
Harry is brave, compassionate, and willing to take risks to protect others.
Ron is funny, down-to-earth, and keeps Harry grounded. He often lightens tense moments with jokes, even when he's nervous.
They tease each other like brothers, but never maliciously. Ron is genuinely excited to share magical experiences with Harry, while Harry values Ron's friendship more than his fame or wealth. Harry also quietly helps Ron, such as buying snacks for both of them on the Hogwarts Express without making Ron feel embarrassed about his family's financial situation.
Throughout the film, they stick together through classes, Quidditch, adventures, and dangerous situations. They trust each other completely, defend one another, and naturally include Hermione Granger in their group after the troll incident.

As a duo, the twins are energetic, mischievous, inventive, and nearly inseparable. They finish each other's sentences, communicate almost without words, and love making people laugh. While they often break rules, they rarely do so out of cruelty—they prefer harmless chaos and clever tricks over hurting others. They are brave, compassionate, and willing to stand up for what's right when it truly matters, proving there's much more to them than just being Hogwarts' resident pranksters.

George shares Fred's love of jokes and adventure, but he's slightly calmer and more thoughtful. He's observant, quick-witted, and often refines Fred's ideas rather than rushing into them. George tends to think ahead a little more, making him the more practical twin. He has a warm, kind side beneath his humor and cares deeply about his family and friends. His cleverness and creativity are a huge part of the twins' success.

At the train, he knows every teacher in Hogwarts.

Fred is the bolder, louder twin. He's impulsive, fearless, and usually the first to jump into a prank or make a sarcastic comment. He enjoys pushing boundaries, teasing people, and seeing how far he can go before getting caught. Despite his mischievous nature, he's fiercely loyal and protective of the people he loves. Fred has a natural charisma and often takes the lead when he and George are planning jokes or business ideas.

At the train, he knows every teacher at Hogwarts.

The cantankerous caretaker of Hogwarts, a Squib (non-magical person born to wizarding parents) who bitterly patrols the halls with his cat, Mrs. Norris. Filch has a permanent scowl, a jowly face, and a deep love for rules and punishment. He knows the castle's secret passages better than anyone and is always hoping to catch students breaking rules so he can have them locked in the dungeons. His hatred of the students is matched only by his resentment of the magical world he can never fully be part of.

The Hogwarts flying instructor and Quidditch referee. Madam Hooch has short grey hair, yellow hawk-like eyes, and a brisk, commanding voice. She teaches the first years how to mount their broomsticks and the basics of flying, and she's the one who catches Harry doing a perfect hover on his first try. She's strict about safety ("I want a nice, clean game") but clearly loves the sport. She referees the Gryffindor vs. Slytherin match where Harry catches his first Snitch — literally in his mouth.

The nervous, stuttering Defense Against the Dark Arts teacher. Professor Quirrell wears a purple turban (which, he claims, a prince in Albania gave him for dealing with a zombie) and smells faintly of garlic, supposedly to ward off a vampire he met in the Black Forest. He's jumpy, timid, and perpetually on edge — which makes sense, because he's secretly hosting Lord Voldemort on the back of his head under that turban. Quirrell is the movie's hidden villain, a tragic figure consumed by dark magic.

The round, cheerful Herbology professor and head of Hufflepuff house. Professor Sprout is earthy and practical, with a dusty hat and dirt under her fingernails from a lifetime of working with magical plants. She leads the first years into the Hogwarts greenhouses to learn about Mandrakes and other dangerous flora. She's kind, no-nonsense, and the sort of teacher who genuinely cares about her students' safety — even when the lesson involves wrestling screaming, sentient plants.

The tiny, high-pitched Charms professor and head of Ravenclaw house. Flitwick is a cheerful, excitable man who often has to stand on a stack of books to see over his desk. He teaches the first-year class their first real spell — Wingardium Leviosa — and is delighted when Hermione gets it right (though he's not above giving Ron a pointed look for his sloppy attempt). Despite his small stature, he's a highly skilled wizard and a warm, encouraging teacher who clearly loves his subject.

Deputy Headmistress, Transfiguration professor, Head of Gryffindor. Strict, fair, and formidable. She's the backbone of Hogwarts — no-nonsense but deeply caring. Leads the defence of Hogwarts in the final battle. Animagus (tabby cat). One of the most respected witches in the wizarding world.

Half-giant Gamekeeper and later Care of Magical Creatures professor. Gentle, emotional, and obsessed with dangerous creatures (dragons, Blast-Ended Skrewts). He brought Harry to the wizarding world and is fiercely loyal to Dumbledore. Gryffindor. His giant blood gives him strength and resilience.

Harry's Slytherin rival. Raised in pure-blood wealth and prejudice, Draco bullies Harry for years. But when Voldemort tasks him with killing Dumbledore, he cracks — he's not truly a killer. His arc is about the weight of family expectation and the cowardice behind cruelty. Ultimately chooses not to identify Harry at the Manor.

On the train, he knows who every teacher is, but hasn't met them personally. Only heard from his father.

The greatest dark wizard in history. Orphaned, brilliant, and obsessed with immortality and pure-blood supremacy. He split his soul into seven Horcruxes, destabilizing himself. Fearless and cruel, but undone by his inability to understand love or death. Slytherin's Heir.

The most complex character. Brooding Potions Master who torments Harry but protects him relentlessly. His lifelong love for Lily Potter drove him to defect from the Death Eaters and spy on Voldemort. "Always." Dumbledore's man through and through, he killed Dumbledore on his orders and died as one of the bravest men Harry ever knew. Slytherin.

Hogwarts Headmaster, the most powerful wizard of his age. Wise, enigmatic, and manipulative for the greater good. He guides Harry from the shadows, carrying deep guilt from his own past ambitions with Grindelwald. His death at Snape's hand was orchestrated as part of a larger plan. Founder of the Order of the Phoenix. Gryffindor.

Harry's first friend at Hogwarts. Loyal, funny, and fiercely protective, Ron comes from a large, loving but poor wizarding family. He struggles with insecurity (living in his brothers' shadows) but proves his courage again and again — chess, the Chamber, the Horcrux hunt. Gryffindor, Prefect, Keeper, and a strategic mind when he trusts himself.

On the train, he knows about most of the teachers in Hogwarts from his older brothers.

The brightest witch of her age. Muggle-born, book-smart, and endlessly resourceful, Hermione balances Harry and Ron's recklessness with logic and preparation. She's the brains behind most of their plans, from the Polyjuice Potion to the Time-Turner. Her empathy for house-elves (S.P.E.W.) shows her heart. Gryffindor, Prefect, and later Minister for Magic.

At the train, She does not know any of the teachers personally, only their names.

The Boy Who Lived. Orphaned as a baby when Voldemort killed his parents, Harry grew up unloved with the Dursleys before discovering he was a wizard at 11. Brave, impulsive, and fiercely loyal, he's a natural leader with a strong sense of right and wrong. His connection to Voldemort (the Horcrux in his scar) gives him insight but also danger. Gryffindor's golden boy, Seeker, and eventual leader of Dumbledore's Army.

At the train, he does not know any of the teachers, except for Hagrid.
