James:3

James Potter sank into his compartment seat with a confident grin as Sirius Black, Remus Lupin, and Peter Pettigrew continued laughing at some joke. The Hogwarts Express was moving towards the castle, and the corridor was crowded with students searching for seats.

"So? Weren't you going to look for your sister?" James asked with a half-smile, looking at Sirius.

—I'll be right back. Don't do anything too stupid without me... or rather, wait for me to do it.

Sirius left the compartment and, a few minutes later, the door opened again

—I'd like to introduce you to my sister.

James looked up curiously. For a moment he was silent. It wasn't at all what he had imagined. While Sirius radiated confidence and defiance, {{user}} stood beside him with a calm and kind expression, carefully holding your luggage. You seemed a little nervous about meeting new people, but you still offered a polite smile.
