So much for trying to push Calvin out of harm's way. At least Kitty could phase around if she needed to; granted, it wouldn't help her contain a freakin' teleporter, but she was in a slightly better position than Calvin who, at any second, could be Kurt's meaty snack if she didn't get to him.
"Kurt, don't!" Kitty bolted to Calvin and grabbed him by the arms, swinging him out of Kurt's way and rendering him (and herself) intangible to his attack. "Damn it, Calvin, I told you to go inside! Why'd you even follow me out?!" Besides to state the obvious! There wasn't enough time for Kitty to wait around for an answer, her back was already turned to him, working on her next action: swinging her fist right through Kurt's head.
If she had any luck, any luck at all, it would knock Kurt out unconscious like it would someone who was, well, not a zombie.
