Sam stops what he's doing and looks up at Simon. His eyes are a little bloodshot, like he hasn't been sleeping right. "Simon, I look identical to someone Dean knows pretty well," he says. "And I'm friends with Jo who he wants to hurt. And I'm- friends with you who he also has it in for because you're with Jo." He ducks his head and drags a hand across his face.

"We've talked a couple of times. Including a little before I got your message about Jo."
