Yeah the ep made me very annoyed at John, so he didn't know about the kid till Sam left but then he hides him from Dean and takes the kid to Baseball games and that is something he never did for Dean and Sam.

Sam, what the hell is up with you? I miss the old Sam before he got off path and started banging Ruby. He is becoming everything he used to hate about Hunters and Hunting. What Dean said was not meant as a compliment!

Dean, I feel so bad for him, that kid got everything from John that Dean tried to get his whole life.

I really hope that what comes next proves that this ep reallly wasn't a shark jump, I avoid spoilers like whoa but this is making me nervous.
