The absolute POETRY it would have been if Dean still had Cas' hand on his shoulder along with the Mark of Cain. That scene in "Meta Fiction" (9x18) when Dean is starting to feel the mark's effects and he looks at it in the mirror after a shower? Just... imagine the camera panning down from his face to his shoulder where Cas' hand is, scarred over, down to The Mark of Cain. THE DRAMA. This? Coupled with the Cas/Colette parallel? The juxtaposition of salvation (Cas) and damnation (the mark)? Absolutely DEVASTATING.
