Ian has probably outgrown his friendship group. Perry is the obvious example. Depending on your perspective, Alison is another one. It's not uncommon for people to realise, as young adults, that their high school friends make better drinking buddies or acquaintances, if at all, than actual friends. Whether she becomes a friend-with-benefits or not, though, Emma is cool; she has strong principles and passions, and is someone who can offer Ian more than high school memories and beer.Related note, Perry's interest in Emma is shallow as fuck. You're interested in this girl, but whine and demand "no politics" when she's talking about one of the most important parts of her life? And not only did you have no idea she's been vegetarian for years, but you immediate shit on the idea of being vegetarian right in front of her? Fuck off, dude.
