What do u think will happe do dean and castiels relatio ship once Cas comes back for this season?
Well I imagine that Cas isn’t going to come back all ok and fine and they can hug, kiss and be happy in 13x06.
Shit is gonna go down.
As for after that, once those things are “sorted” I expect still some reticence, some worrying about their feelings being unrequited etc.
They also cannot advance to their happy endgame TOGETHER unless they themselves have accepted themselves and feel self worth, so we need Dean to complete his denouement from his climax in 12x22 and for Cas to complete all of his journey too since his death.
So they have to work on themselves first before they can be together, so I expect lots of this and also a build up of their feelings being framed as heavily romantic (building on the subtext of 8 years and the especially strong subtext of season 12) before hopefully something very very strong in the finale.
I would LOVE for 13x23 to give us Cas’ decision to be Human, after a build up of re-explaining why this is a good thing for his character, so that is the finale, alongside Jack helping them defeat Lucifer.
I’d then love 14x01 (because it’s their 10 year anniversary!) to just open after all this Destiel build up and now with Human!Cas with an alarm going off, Dean in bed with his eyes closed before hearing a rustling of sheets, we see Dean smile and as it fades out we hear “Dean” in Cas’ husky voice before Dean rolls over and says “morning Cas” softly.
OR the first half of season 14 is the Dean/Cas build up with Cas in the bunker, human etc as we read in fanfic, with the Destiel climax moment in the midseason finale… it depends how long they’re gonna go on for :)
Ideally human!cas and destiel should be separate but they can be approx the same time, as long as it’s clear that Cas choice to be human doesn’t rest entirely on Dean :)
