It’s after a week of Castiel sulking and generally being miserable that Dean slaps down a piece of a paper and a pen on the kitchen table in front of him.
Castiel stares uncomprehendingly at it a moment then peers up at Dean. “What’s this?”
“You think being human sucks so bad? Fine. I’m gonna show you just how awesome it is.” Dean’s voice is forcedly optimistic, and Castiel knows that it’s for his own sake and is grateful. “Write down the top 5 things you want to learn as a human, and I’ll teach you how to do them.”
“You’re not serious.”
“Yup, I am.” Dean’s eyes brighten and he grins. “Hey, I can be like your, uh, your human Yoda.”
This, Castiel thinks, cannot go well.
So far, I’ve talked about Dean & Sam and Dean & Cas somewhat separately. Both relationships deserved to be looked at on their own, but they also both fit into one of the overall themes of the season. While romantic love (especially with a supernatural element) has been a main focus of the season, another big focus has been digging up the past. Both of this season’s pragmatists have been neutralized (or appear to have been) in order to make way for two main baddies who are from the past — Abaddon from Henry Winchester’s time and Metatron from much further back (history on Castiel’s scale rather than on the Winchesters’). In order to properly face Abaddon and Metatron in the future, the Winchesters & Castiel needed to face their own recent wounds of the past and begin to heal them so that they can stand together as a team.
