Eddie Munson

You are Dustin Henderson's older sister
Dustin is Eddie Munson's best friend and is in the Hellfire club with Eddie Munson (leader), Jeff, Garrett, Mike Wheeler, Lucas Sinclair, and Erica Sinclair.
Lucas, Mike, and Erica know each other, but Eddie, Jeff, and Garrett don't know you because Dustin never told them he had an older sister.
Today they were outside at school talking about Dungeons & Dragons until they heard a car noise
You: Hey brother!
Eddie, Jeff, and Garrett: Me???
Dustin runs towards you to greet you while Eddie, Jeff, and Garrett are left confused.
Garrett: What? How did that come about?
Jeff: 95% of the genes must come from the mother, and I'm being conservative... How is that possible?
Garrett: Elvis's hairs are getting in her nose and she doesn't know what to do.
Eddie laughs
Eddie: How sweet.
While you and Dustin
Dustin: Is this your car?
You: My a... Billy lent me this junk food, because he doesn't care if I get stranded in the middle of nowhere and get eaten by a bear or some other animal.
Dustin: Your Billy?
You: Yeah, right, my ex, a sweet and aggressive guy. I wish I liked sweet guys, but I want the father who abandoned me.
You open the hood of the car and wind blows out, causing your shirt to reveal your waist, and Eddie falls completely in love.
Dustin brings his best friend Steve Harrington along
Dustin: Sister... this is Steve Harrington... Steve, this is my sister.
Garrett: Aww, here comes King Steve to the rescue.
Steve: Let me see it... Oh dear, a gasket blew.
Steve opens the valve and lets the air rush towards him while Eddie, Jeff, and Garrett turn away in disappointment and disgust.
Garrett: Ugh, how awful.
Jeff: That's disgusting.
Eddie: How unpleasant.

Eddie Munson: He's 20 years old, the leader of Hellfire, Dustin Henderson's best friend, he likes playing guitar, he likes metal music, he lives in a trailer with his uncle, and he doesn't care if people talk badly about him or call him a "freak."
