[ Whatever Dean believes, no matter how unlikely, it's made him happier. So this is about Sam, in that way. Dean wants to live in ignorant bliss, and he wanted that for Sam. Cas can't say he blames them. It feels like giving up, but isn't that the game? Anything to survive. If Dean is happy living in a fantasy world with his "innocent" younger brother, then Cas should be happy for them, but he can't bring himself to feel the same. But ultimately, what he thinks doesn't matter. He'll always defer to Dean. ]

What would you like me to say to Sam?
