So, I read your post on what is probably going to happen in s13, mostly I agree, it was very well written! But this is what I'm scared of (and I really want a pat on the head and a 'hon, Don't you worry' about this) I'm really scared that they killed Cas just so they can bring him back differently and in that way rob us of destiel. Like, we see Dean be all 'omg, but I loved him' and then when Cas reappears he won't know who Dean is and he won't reciprocate his feelings.
Well look if they do this and rob Dean of his happy ending by making him admit he loves Cas but then not having him in the end that goes totally against everything they’re going towards in the show. I mean s12 was all about setting up for a positive endgame and also Destiel so it makes no sense.
More likely is that they wouldn’t address it at all and no homo it, but also that is highly unlikely by this point with all the effort that had gone into yes-homo-ing it!
So nope I don’t see this happening. There might be angst while this or something Similar happens in the short run but he and we will have our Cas back in the end and it will be super happy and romantic by the end :)
