still brainstorming, but i'm thinking that she moved to new york in her early teens, so he would have been the dare kid and she would have been the new kid on the block so they sort of just stuck together and became really close? she would have become super protective of him over time. she would have (playfully) given him shit for his resisting to drink, but respected his decisions and never pushed or teased him except for jokingly. but then when he finally did let loose, she was all about egging him on and what not, and probably maybe contributed to his slightly excessive drinking.
