The fact that when shit hit the fan he realises he's in love with dave and tells him that. Though it does help that in one of the comments here you said ty was ''so far in the closet he's finding narnia''.
I think I ran into a line like that...I’m pretty sure Dave asked to be held for a positive feeling, and when Dave said I love you to Ty, he simply replied “You too, Dave.” That’s it....pretty sure the last thing they’d be thinking about is being in/out the closet, but to each their own...
