There were not many instances where Luke would let any of this bother him, but he couldn't stand it when Sylar was upset. It made that protective streak in him flare up and in this case, it caused him to almost completely want to shut down.

His eyes were hard as he pulled himself away. No more fucking touching. He couldn't take it right now. His skin itched at the loss...which was actually pretty crazy when you thought all about it.

"Do you see the sort of person you are without me?" Luke gestured towards the door. "A little less fun, but you're a hundred times better off. And you don't fucking need me anymore. Don't even say you do."
