Man, I really feel bad for Sam. He isn't get comfort from the person he needs it from the most. Come on Dean, snap out of whatever shit this is. *glares at writers* Liked the first two episodes, this one just made me upset. Random Kitsune thing is random. O_o I almost started to ship it but it's just too random. And lawl 'Amy Pond'.
I do like how they showed a little back story as to why Sam is more sensitive towards others who are 'monsters' though.
Finally about Dean...
HE FUCKING KILLED HER
YOU FUCKING ASSHOLE. I seriously cannot process the rage right now. So he makes this speech about how people are who they are and the last shoe will drop, but let's the fucking kid go? Because he doesn't have the nuts to kill a child but is perfectly fine with slaughtering a Mother that can't help what she is and hasn't harmed anyone?
Go back to hell, Dean.
And stay there.
