There wasn't enough space in the car. And Tristan is a big guy. It was the only way to be close enough to see his wounds. But also Wren doesn't have those kinds of inhibitions. In the flash back he'd get naked in front of Tristan. He just saw him as a kid. Not a potential lover.
While we know Wren's just a parent figure and got no malice, Ima be fr there was still space even if just a lil, sitting like that is for couples only even if the other person is bleeding and his getup rly got him trapped in allegations lol
no literally
i cant get the car scene out of my head bro, why was he sitting on Tristan like that
