I had thoughts about...
I liked it. I liked that the boys were working together. I loved that they were standing their ground against Castiel, and I really loved that Castiel spent a while as an action figure.
I liked wee Jesse, although if he was supposed to be 11 years old, then he is the weediest, most undersized 11 year old ever.
Seriously, I felt for the poor kid - so alone all the time. I think that the fact that his parents were only shown sleeping was a very significant choice. There he was, this teeny wee kid who had been rejected by his real mom and left to rattle around in that big house.
There were so many parallels with the Winchesters when younger - despite having a stable home he was pretty much fending for himself. I felt so sad for him. I also felt bad for Sam. How dare Castiel get into Sam's face like that. What about *his* choices? He's the one that could have helped Dean in time to stop Sam, but instead only cut him loose when it was just that teeny smidge too late to prevent him from killing Lilith.
Go back to being an action figure, Castiel, and think about things some more.
I love the way that show uses humour to point up the poignancy of events as they go, and I really think that this ep put them back on track. There have been amazing episodes in the past, and then some that are not so amazing. This one will be remembered by me long after last week's ep has faded from my memory.
I loved Sam and Dean's final conversation in the car. Poor, poor damaged boys.
