Part 2 Ty is dating Quinn!!! As of a few days ago. While this wasn't announced on the journals or anything, it became public knowledge after he climbed the Ornery Oak to tie a ribbon on the top for her and after some very public displays of affection. The two have been FWB for months and he's taken her to a couple of dances, so this likely isn't a huge surprise. One complication, though, is that she's the ex-girlfriend of his best friend, Rafael. While this sounds potentially messy, though, Ty and Quinn and Rafael and Leo (Raf's current boyfriend) are all very close and hang out togethre a couple of times a week at least. Prior to getting involved with Quinn, Ty had a handful of casual sexual partners and was openly not interested in getting into a relationship and there are times that he doubts whether or not he's meant for this sort of thing. Mostly, though, that doubt doesn't show and he's all sunshine and rainbows right now.
The only other complication (which a handful of the Mean Girls might know about -- especially after the PTC) is that he's the youngest son of a very wealthy, very traditional pure-blood family that would definitely not approve of this match.
Gavin ...is brand new! So there's not much to say here. He's single, he's never dated, and he spends almost all of his time with his twin brother. Shut up. That's not weird. He's flirted and shown a passing interest in both girls and boys in the past, but it's never gone anywhere. I'd be happy to pin down some specifics if anyone wants to have a minor connection to him on that front.
