You can headcanon (and now I'm coming up with my own headcanon) that you get back, freak out to Cullen about Mythal, cry on the bedroom floor or whatever, and not know what the hell is going to happen to you. All you wanted was to know how to defeat Corypheus, agreed to get a bunch of knowledge that you don't know what to do with, and only later found out that, oh yeah, Mythal's alive and well. So, I guess my headcanon is that the Inquisitor has just as much, if not more reason to start breathing into that paper bag.
Oh that is good. I just finished the part with Flemeth and I'm breathing into that paperbag myself for the stuff she and Morrigan told my IQ, Quizzie herself is definitely going to run over to Cullen for a good long cry about how none of this stuff makes any sense and she was only trying to do the right thing and now heretical gods and witches of ancient legends are telling her where to go and what to do and the Maker will probably burn her in holy fire for this and damnit maybe she should have died in that explosion after all because all she does is screw everything up, etc. Good thing Cullen is the sweetest, most gentle and understanding thing in the world, because he'll have to be very patient and kind with this particular panic attack.
Actually seriously considering making the well my canon for now. The content you get with Flemeth by drinking yourself is much better than just watching her argue with Morrigan otherwise, and all this discussion about how it affects the IQ's relationship with Cullen is making for some really interesting scenarios between them about magic, religion, mutual trust, etc.
Another thing that only ocurred me now is that Cullen is very experienced with nights of restless sleep and hearing voices/songs in his head, so if anyone can help her through that, it's him. It balances things out a bit, sharing the onus of supporting each other through issues that won't really ever go away. Hmmm.
