Someone made a comment like this on a forum just after The Beginning of the End aired and I couldn't resist making an image out of it, I could easily see this going on in hell after Sombra was destroyed the second time. (This is my interpretation of what pony hell could look like, as "Grogar" simply refers to it as "the darkness from which you were summoned" and Tartarus is not it)

Of course Sombra might counter with a comment about how Grogar wanted him and not the Storm King.
