It wasn't that he didn't trust Shane the person, because all in all he did - it was Shane the wolf he didn't trust one bit, and the risk of another transformation happening was just too great. He'd be the perfect target for a wolf, a literal sitting duck. Cole didn't particularly feel like dying anytime soon, and he'd feel much better in his own apartment with locked doors where the only animal was a perfectly harmless cat.
He avoided looking at Shane, because despite it all he felt faintly guilty for so obviously objecting to stay in his apartment. God, he really was an idiot - who felt guilty over something completely justified like that? This was where being nice had gotten him, with staples in his legs and a bunch of pill bottles in his foreseeable future.
"Thanks." Cole had never been as grateful to one person as he was in that moment. "I just-- I can't stay here." He kept his voice low, even though Shane was in the bedroom. He wanted to sleep without having to worry about having his throat torn out.
