I really think the structure in the last episode hammered down a lot of what Dabb is trying to say, especially in regard to Destiel. We as the audience of course should know that there are things that just don’t happen on screen because we just see a very very tiny glimpse every week but you can forget that very easily when you just watch along because usually Supernatural is a very procedural show.
But starting with 12x12 (of course before that, too, but I feel like we’re having a theme here :P) and the Tarantino-esque episode they started really putting emphasis on the fact that we just don’t have the full picture. That there are things happening that will have to be explored later, that make scenes that happened before much more clearer… that was the whole episode.
Then we had 12x19 with the mixtape. Again, we should know that Cas and Dean (and Sam) spend time - domestic stuff - outside of the episodes but the mixtape really hammered down that this is important and things that may happen off screen may come up later. Especially in regards to Dean and Cas.
And now? 13x01 was a beautiful episode. The stuff we got from Dean grieving at the end of the episode was so powerful. And we - at least my whole dashboard :P - could feel throughout the whole episode that there was something missing, something that should be there. Even without the spoilers we already had it was obvious: how did Cas get there? Why is Dean’s hand bleeding?
Technically, the episode could have made sense without these scenes but it would have felt very wonky. And it’s just a good feeling to get recognition, to realize that yes, there was something missing, we’re still missing part of the puzzle.
Which leads us all to Destiel - all these little tidbits of things shown out of order can be used to show us more about Dean and Cas’ relationship. Things that are missing but make total sense in context and that make scenes seem different in retrospective.
Things that by all means should be there because they make the show better. Because we can pick up these clues and see that there’s *something* going on. And if that’s Dabb’s approach to Destiel then I’m very much looking forward to that.
