Dean raised a brow and even held his hands up for affect. Amused. And trying so hard not to grin at how short Sam was. Geez, he'd almost forgotten. He felt bad for his brother, though. Poor kid had been through a lot. Which didn't quite stop the swell of pride that went through his chest. Sammy'd always been a resourceful kid. And with all that they were going through at the moment. All the irritation, the anger, Dean's resentment of Ruby .. well, he'd forgotten about that. Sam's resourcefulness and that feeling of 'that's my little brother' he'd get but never admitted to when someone praised his kid brother.
"It's me, pee-wee." He said, carefully approaching but keeping his hands out of the open. "Dean. Not exactly the brotherly welcome I was expecting, but hey, it'll do." He joked.
