For a moment, Sam didn't say anything. There'd been Jake and Ava and Max, and while Max was a clearer case in that he'd obviously been pushed in ways that had nothing to do with the supernatural—Jake. Jake was a question mark, wasn't he?

Sam hadn't ever experienced it for himself, hadn't ever wanted to, but he couldn't forget, either, that way back from the start, when he'd been trapped and he'd thought Dean was going to die—there'd been something there. That it probably wasn't the exact same as what Teresa was referring to was beside the point; the fundamental concept was there.

"I'll remember that, then," he replied. "Anyway, I." He tucked a strand of hair behind his ear, stopped just short of clearing his throat. "I shouldn't be taking up any more of your time. Thanks for talking to me, though."
