Dean blinked when he heard a baby wailing from upstairs. He jogged up the stairs leading to the second floor, taking them two by two, blinking when the wailing came from Sam's room. Opening the door, the sound was hard to locate at first because it was buried in blankets, but once he moved to the bed, the baby wasn't hard to find.
He picked it up and cradled it to his chest instinctively, blinking. "Sam - no, that's too fucking weird. You can't be Sam." He held the baby at arm's length, examining it. It had Sammy's huge head. And it looked eerily familiar. He shook his head and tucked the baby into an arm as he looked around the room for anything Sam might have left. A note that said "Oh, I found a baby that looks a lot like me, be back later."
