Just something I've been pondering

I've been wondering about Castiel and his powers. It seems the general consensus of fandom thinks that Castiel has been losing his powers bit by bit since he returned, I've seen this being referenced a lot in fics and also in fandom discussions. However, are Castiel's powers really dwindling away?

( My thinky thoughts, let me shows you them. )

This is just me, having thinky-thoughts at like, early in the morning. And it has to do with Castiel, go figure. Heh.
