Seems like your "break up" theory was right on point with How betrayed Dean must be feeling at this point.
Yep, I don’t know if you just saw my last post but I’m feeling that there is a choice now from Dabb as to whether to continue on the ‘standard’ SPN trajectory and have a ‘rule of 3′ s6 + s8 + now Cas is brainwashed / makes bad decisions trope with Dean crypt scene - ing him back etc etc or if he is going to go a new, different way….
The break up / separation was key to this episode and the end of the season so I’m glad it did go ahead, and in the way I expected with it being more of a ‘choice’ thing at this point.
The fact that Destiel was so core to this episode, which is all about the future and the future arcs of the characters, is super exciting to me :)
I mean, Dean is feeling betrayed, but also… he was betrayed all episode but he STILL defended Cas to Sam, he acknowledged what Cas was doing and why he was doing it. I think he’s finally figured out that Cas is doing so much of this FOR HIM, with the best intentions, again, not EVERYTHING is about Dean, but so much is and the rest is all for the RIGHT reasons.
I mean the bedroom scene was literally them both revealing their feelings in the best way that they could and each acknowledging this up to a point. Cas shows his through trying to protect Dean at all costs and putting himself in the line of fire, always leaving Dean in order to help him. Dean shows his through trying to repressedly making half gestures and saying half truths, because he can’t quite give it all yet and basically asking Cas to stay.
It was fantastically written to show that they basically now UNDERSTAND each other’s views and feelings towards the other, even if they’re not 100%, they are WAY closer than the… whatever, like 20% they were at before?!
