Cairax could have killed Legion

He was pretty sure the thing at the Mount would’ve killed him. He didn’t know how, but he felt it in his gut. If he’d stayed there it would’ve torn him apart. Somehow.
The thing that’d saved him in the end was the other exes were changing too fast. They didn’t have time to do much damage. They got tall and sprouted fangs and claws, like werewolves or something—enough to **** up a regular person, easy. And then they’d pop open like hot dogs in a microwave and fall apart. There’d been a break and he’d thrown himself away, like diving off a bridge. He didn’t care where he ended up, as long as he wasn’t there.
