Wow. There's some serious fan-girling going on in this thread.
Rather than argue all day about an awful character and poorly-thought out writing and numerous plot holes, I will just say this.
Quinn is poop.
If it's such an awful character with such poorly-thought out writing and numerous plot holes ... well, then there'd be no reason to respond to anyone's fangirling of the character, hmm? Heck, the fact so many people have to post so many threads describing this one single character seems, to me at least, to indicate the writers of the story did a pretty dang good job, hehe.
