Well the report did say that there were no survivors and there was a picture of him with the others but it was very ambiguous. Isn't it somewhat peculiar that the dudebros mention to kick him out of the bus right before dying? I mean why even mention it? I dont know, maybe I'm overthinking it.
edit: Then again I dont remember if enough time passed between them saying that and emma flipping their shit upside down. I dont know I just kind of think he's still alive.
edit2: I asked my gf if she remembered the scene. She says they said to throw the driver off the bus and not Kyle and that there was no time for him to be removed from the bus. So I guess that's that. I STILL BELIEVE HE'S ALIVE!!! ALIIIIIVEEEEEEE!!!
