'Supernatural': New preview with Sera Gamble for Episode 20

Many of us have been looking forward to this Castiel-centric episode since Paley Fest when Ben Edlund announced that he wrote and directed it.

A new preview was released for "The Man Who Would Be King" this morning with Sera Gamble and new clips for the episode. Take a look:

Personally, I saw his partnership with Crowley coming from a mile away, way back when Castiel supposedly killed him. Yet, I am still uncertain as to how the boys are going to take it, especially Dean. It's clear that Castiel has been suffering with his choices all season long, and even at some points, has tried to come clean. It's clear that he is terrified about what Sam and Dean are going to think.

Why wouldn't he be? If it's true what some of us have been speculating, that Castiel is responsible for bringing Sam back from Hell without a soul, then Dean is never going to forgive him.

The aspect of this preview that has completely thrown me is that Castiel looks right into the camera at the end of it and says, "Let me tell you everything."

I know I'm not the only fan freaking out about this. Of course, he could just be looking at one of the other characters...but when has Supernatural ever done something quite that simple? Has Ben Edlund broken the fourth wall again this season by having Castiel telling his story to the viewer?

I definitely can't wait to find out.
