"So go-- open up a yoga studio. The world is your oyster, man, you're free." He seems just a touch incredulous that he has to spell all this out, even though deep down... he gets it. He does. He gets that Cas— this Cas— has gone from the strictly regimented armies of Heaven straight down to the strictly regimented armies of Winchester, he just hates that. He hates who that guy was. He hates that he had the potential to become that. He hates the fact that that guy is somewhere inside of him still, probably, and he hates that he's more that guy to this Cas than who he actually is.

And he's not altogether sure there's a significant enough difference for that to matter.
