Yeah, i think Q is just quirky enough that if he does have a random thread or a post or something, he ends up building meaningful CR rather than the standard exchanges that Anissina would have given. It is a little sad, but a true fact of life!
I'd feel sad to see Q go, but I'd understand.
And... going out on a limb here, but I'd tentatively say Lloyd from Code Geass even though I haven't seen enough of CG to say yes or no. From a canon I know, I'd try my hand a Drusilla but I wouldn't be able to do that here in Marina because in my head, Drusilla and Diva overlap to much.
If Kefka tried to kill Jennifer, which character besides Yuuri would try to step in and rescue her first?
