Lynn(Cat), yes, I've thought of that, why Mac can touch him...but I think there is something to JB saying that he's "damned"...or something to that, but he also "converses" with V'lane...and remembering when Adam was "semi-cursed" and really hadn't lost his powers, I think theres more the Aoibheal & JB & V'lane than (obviously) we know. It's all so fun to speculate.
