What I said on the first posts stands; my character, Mark is a computer science major in college, and a total geek; although he's been making electronic music remixes and original hip-hop stuff under pseudonyms (Tesla for the mixes, DJ Destro for the rap stuff); his tracks have gotten quite big on underground circuits. He's recently broken up with his girlfriend.
The sister, Abby is a goth girl; with some nerd tastes acquired from her brother (no pun intended); I'll let Daylily tell you more about her. She's been in love with her brother for a while now, and a few days ago she managed to drag him to the Gaslight Club; a club where there's a backroom with no booze served, for underagers... they hang out, have soda and non alcoholic beers, listen to music, dance, play games, etc.
During their whole time in the club, Abby was being very, ahem, nice to her brother, and when they got home, they ended up making out.
Carla, your character, has been Abby's best friend since they were little, and she's had a crush on Mark since she was 12 or so... and lately, she's noticed that Abby's eyes light up when she talks about her brother; in fact, her dragging him to the club was the culmination of months of planning and talk. Maybe Carla is even interested in Abby too...
Shall we open a post with Mark and Abby showing up at the club again?
