So we know Sam'll cure Dean but we also know MoC is still in the picture and Jeremy said that we'll see whether it's still got the same affect on Dean. Some people were disappointed that they're wasting another great story line for Dean by making him come back to human quickly. But i think demon!dean might not stay longer than first run of the episodes but MoC will remain as a problem and they'll deal with it later in the season. I was wondering what your thoughts were? Love your speculations :)
Did I miss a spoiler? Do we know for sure now that Sam will cure Dean? I mean, we all kind of expected it and I wouln't be surprised, but was it confirmed anywhere particular? :)
Anyway, while I would love to see Demon!Dean as long as possible on my tv screen, judging from the info we got, Dean might be cured sometime around the 6th episode. If it just comes down to my personal wishes, then I'd loved to see it last half a season like Soulless!Sam's arc did.
That being said - and like you say as well - there is still the MoC and I believe it will be permanent. I have said this before, but I think it actually makes sense for them to have Dean back to human relatively early since it's more of a symptom, but not the cause of the problem. Even the MoC really is only an extended symptom of the problem, but in general it serves as the catalyst for Dean's problems.
I don't think - or rather hope - that this won't mean a "wasted storyline", because I think the true and meaty stuff will come for Dean once he gets some sort of grip on what he did and has to work through what he did and that it was all him.
And I am extremely excited to see Jensen act the hell out of this struggle inside of Dean between light and dark.
I am probably a broken record about this already, but I personally would like it most if he cannot get rid off the MoC. but has to find a way to control it, find balance and the more he heels and gets in tune with himself the more it fades away. I guess I like the idea of it serving as a sort of silent reminder, but I know many hate the idea.
And as an ending note - and yes, I probably said this as well already ;) - I expect/hope around mid season to Dean relapse badly on demonhood and be worse than ever before, because whatever Sam does to cure Dean will only be temporary just like the wall Death created for Sam.
Thank you for your question! <3 <3 <3
