Re: "Quinn knows the power she has over him, that sheās done what she has wanted with him in the past, and in his current state of mind, heās not about to let that happen ever again." I agree but does that apply still? What could she ask him to do that he would have *moral* objections to?
Itās not about doing something morally questionable, because at this point obviously he wouldnāt have any problems with that. (Iām going to disgress here, but I think that was never even the problem, actually. I canāt think of many morally questionable things Quinn did because Carrie asked him to. He questioned Carrieās moral transgressions, and didnāt cross the line if he didnāt agree with. His moral transgressions were on his own. She had power over him, but not THAT much. The way Carrie overpowered him is mostly represented in making him do things he knew werenāt good for him: staying in the CIA to help her clear Brody, coming back to Islamabad; or stopping him from doing things he thought he had to do/wanted to do, like killing Brody or blowing up Haqqani.)
Back to the question, itās not just about something Carrie could ask of him, actually. I think itās about him letting his feelings for Carrie control his actions. Letting āhisā feelings have power over him, itās like letting Carrie have power over him.
It seems like a battle with Carrie, but really the battle is with himself.
