Hey guys, just wondering…Y’all remember how John told Dean he’d have to kill Sammy if he couldn’t save him? Well, what if he wasn’t referring to the demon blood or destroying the world? What if John was referring to this “wall” thing inside of Sam? Like, all along he knew everything that happened would happen and that in the end the wall would break and Dean would have to put Sammy out of his misery?

Just an odd thought that popped into my head…
