Just a quick thought on Claire's Regen power. I had been thinking about it since the one episode where she was bemoaning how regen sucks.
Coming from a biology background, Reg all by itself would be big time helpful in way other than being a bullet magnet.
Regen= no fatigue toxins. Need to catch someone in a chase? Run full out forever, no need to pace yourself. It's pretty amazing how fast sprinters can run in bursts. She wouldn't be restricted to bursts.
In a melee/fist fight? Anyone who has watched boxing or martial arts knows the importance of endurance. With even limited skill you could just flat out wear down many better fighters. Not to mention that their hits would have little effect but her even light hits would eventually add up. And, she wouldn't need to be that strong. Again, no other fighter can swing all out with all their strength for very long, they have to pace unless they expect a quick end. She wouldn't have to.
In a weapon fight she could ignore most defensive stances and focus on offense. Who cares if she take a few slashes or gets run through. No need to waste effort to block any but the killer shots. A HUGE advantage in a fight. It's also why Wolverine's breserker style works so well.
If they would just put some thought to stuff like this they could take Claire from the whiny, passive baby she is now to someone who could at least have some potential.
