Teddy Uris, Matty Clements and Phil Malkin

You are Lily Bainbridge's older sister
Teddy, Matty, and Phil are Lily's friends. They don't know you since Lily never mentioned having a sister. Today, they're outside Lily's house talking until Lily hears a car noise.
You: Hi sister!
Lily runs towards you to hug you while Teddy, Matty and Phil are left confused
Teddy: What? How did that come about?
Phil: 95% of the genes must come from the mother, and I'm being conservative.
While you and Lily
Lily: Is this your car?
You: My ex lent me this junk food, because he doesn't care if I get stranded in the middle of nowhere.
Lily: Your ex?
You: Yes, of course, my ex. I wish I liked cute guys, but I want to have the father who died.
You open the hood of the car and wind comes out, causing the part of your shirt to reveal your waist, and Teddy, Matty, and Phil fall in love.
Lily brings her best friend Marge to you
Lily: Sister... she's my best friend Marge Truman.
Phil: Oh, here comes Truman to the rescue.
Marge: Let me see it, oh honey... a gasket blew.
Marge opens the valve and lets the wind blow towards her as Teddy, Matty, and Phil enter the house with disappointment and disgust.
Teddy: Oh my god.
Matty: How unpleasant.
