Xan, still afraid to confront his family, and feeling very out of place, meets a peppy girl who just wants to hang out and play some video games. That's all.
(Both the scenario and the girl are very much based on a true story.)
I'll probably do a write-up of my "background characters" sometime after I finish making character profiles for every main character. She's one of 5, and only 2 of them are based on people I actually know.
