He couldn't help it, even if Dean was accusing him of being something else. Circumstances weren't in his favor, but there had to be some way he could convince Dean it wasn't a trick. He didn't know what his kids had been through the last few years without him. So he knew it wasn't going to be easy, but there had to be a way. Even a tiny sliver of hope would do. "Remember at the hospital. I told you something.." He didn't elaborate. He wanted to watch Dean's reactions. See if he still remembered.

His mind kept wandering to that place. "Look around Dean. Something is happening that brought us together."
