User blog comment:Twilight Despair 5/Abaddon as the Season 9 Big Bad?/@comment-1509826-20130416210140

It would be nice to see her again, of course they would need to give her a new actress, as no one's going to buy the old one coming back. If she does appear in the final, she won't be working for Crowley, he will be kneeling before her, Abaddon is clearly a much stronger demon, she's somewhere on Alastair and Samhain's tier, Crowley's not really that powerful, sure he's still tough, and strong and all, but he's still the weakest higher demons (depending if you count the seven deadly sins as higher demons) so her working for him or teaming up is out of the question. As for having her as the big bad?

I don't know, I loved the character, it was her that brought back my faith that demons could be used as affective villains in the show. But I don't know if she could hold the role of main villain, it might get a bit repetative. Still its possible, and there have been worse candidates for the big bad (or atleast seemingly worse). Won't mind if she did come back, although it would probably be difficult to match her first opinion.

Mind you, if she returns we might actually find out who she was working for, as she's described as simply a "highered gun," she clearly works for a much more powerful demon, most likely Azazel he was king when she was around, but if there going to introduce an even greater demon for her to follow, I'm hoping its Asmodeus.
