@HerLastWords omg. i can't believe ur asking me about stuff for the sequel. i'm officially dead.
1. but anyways, I'm a huge fan of Grant (as you already know), but also i really like Lacey, Tristan and Seth (btw in my head Seth is a mega-hunk who closely resembles penn badgley), and I think Sammy should be part of it too. idk, there's a bunch of background characters that you haven't really spent much time on that i love for no reason. but Grant needs to be super important. (and gay too if you dont mind...)
2. i like seeing the alternate POV's because it adds depth to the characters (i hated Halden before his chapter and now i find him sympathetic and stuff).
3. i think it should b either with tristan or maybe just independent hartley because if you add a new guy, it'll just seem a little rushed and random.
