Ty feels like shit about this, honestly. He wasn't as close with Wes as Rafael was, but he definitely feels like he should've taken his struggles more seriously and feels guilty that he didn't reach out more. He wasn't the one making jokes or bullying Wes, but he didn't do much to stop that or help him feel better either.
There's probably an undercurrent of 'well, I hope you're happy' for Chris and Robin, but he's pretty bad at maintaining a cold shoulder and doesn't want to fight. So we'll see how that goes. Mostly, though, he's worried about Rafael because he knows how much this will hurt him. He'll be a protective and attentive and worried buddy for a while aaaaand, if he gets the impression that Raf doesn't really want to talk but he still wants to hang around, there will likely be hanging out with a squirrel time. Don't be sad, Raf, look how cute he is! (He's not five, Ty.)
Quinn will likely hear about all of this from him too.
