That overwhelming feeling that had taken Sam over upon seeing his father pressed itself just a little bit harder when he saw the look on Dean's face in response to Mary's presence. He didn't remember. Dean had forgotten. Mind wiped, blank slate. No more memories of their mother jammed into his head. Just...nothing. For Dean, right now, he was seeing Mary for the first time since...well, since she died. Sam couldn't fight off the concern that crept it's way across his face for his brother; though, really, that battle didn't matter in the end. Once he heard Dad's voice directing itself at Dean, he found that concern immediately shifting into that same sense of shock he found himself carrying whenever someone he knew came back from the dead. That and more. John Winchester was a whole different chapter in his life. The last time they had spoken, Sam had been angry. Rebellious. Now Sam saw things a little differently. What Dad did, the way he went about things, what he must have gone through - Sam sort of got it. Now that Dad was alive again, Sam planned on making sure that he knew it. Their inability to understand one another had been their undoing before. Sam wouldn't let it get that way again.
"C'mon, Mom," Sam said, almost gently. All around, this situation wasn't turning out to be all that easy for anyone. Yet if Dad really did jog on through the tests that they had prepped for him with flying colors, then it'd turn into something else. Something better. The Winchester family would be whole again for the first time in nearly thirty years.
Don't, Sam thought sternly, don't let yourself get caught up in hope when you don't know if it's really him yet.
Hell, Sam didn't even know if that was really Dean either. He had last been reported as dead, yet now he was posting on the boards all alive and well as if nothing had ever happened? How? He'd have to check him too. They couldn't afford to take any risks; Sam had a lot to be cautious about, especially lately. Determined to sort this out as quickly as possible, Sam stepped forward and led the way to the duo ahead. Sam got close, but not too close. He didn't trust what his eyes were seeing. Not yet. "You guys know the drill," Sam said carefully. "Silver." Sam pulled his knife out and flipped it open. Handle out, he extended the knife to John. He tried not to look him in the eyes when he did. It was easier that way.
