Jeremy Carver on Demon!Dean and how the Mark of Cain complicates getting Dean back from being a demon (x)
As much as I am excited about Demon!Dean running wild and causing all kinds of havoc. Drinking, smoking, doing whatever he feels like doing, getting into bar fights and whatnot, I am also very very excited and looking forward to the aftermath of Dean’s time as a demon. It seems we’ll be in for a delicious, tragic, angsty arc that is going to spark some wonderful character development and might involve some serious soul searching not only on Dean’s, but also Sam’s and Castiel’s end (which in Cas’ case might be an interesting thing on an all new level given his grace is burning out - I still would like it if somehow it would turn out Cas would not die, because he already grew a soul or something). Though of course in Dean’s case in particular. I keep holding on to a bit of hope that we’ll get a “The Man Who Knew Too Much”-episode with Dean in which he has to put himself back together again.
Also: Since we can assume that Dean enjoys being a demon so much, because all his worries and pain is gone and he embraces the party life, etc. to the fullest (as well as some other way more darker stuff it seems) and Jensen talking about Dean as a ~heroin addict, who has found the magic cure (see here and here), it’s going to be really interesting to see how we’ll see Dean deal once he comes back from being a demon [while still carrying the MoC - I rather like it if he had to keep it permanently as a sort of silent reminder (Sam after all had to find a way to deal with the demon blood within him and control it as well, so I would like to see something similar for Dean) or fading over time the better Dean gets emotionally and mentally and the more he heals] and how and if he’ll try to substitute the feeling with something else. Because Dean’s journey is really only starting once he is back human and has to face himself.
That is why for a while I could actually imagine Dean being in an even bigger danger of overdosing on whatever substance/being suicidal than ever before, because he had the ultimate taste of freedom and ~happiness while being a demon and it will be all about him figuring out a healthy way to fill the hole in his stomach… and his broken heart that being a demon or carrying the blade so perfectly numbed and made him forget about…
