Logan was thrown like a ragdoll, and he went tumbling into Emma and Karl, enough to knock them down and have them be trapped underneath his weight.
"Could stand to have a little help," he snarled as he got up, glowering at the both of them. Standing around and saying 'what the fuck' or making some snide comment about Carol really wasn't going to help. "Good to have her on our side, but what do we do with her when she ain't?" Invulnerability. Super strength. Logan couldn't seem to land a hit and he wasn't sure what to do other than continue to tumble with her until she got tired. If she got tired. She probably didn't get tired, the bitch.
Logan could only hope that she was psychically vulnerable. He couldn't remember if she was or not. Knowing his luck? That wouldn't bother her, either, and they'd continue to be screwed.
The moment he was up again, he was lunging for her again. He had to keep her distracted, keep her from hurting anyone else who wouldn't heal. Logan might not have been able to do damage, but he could get her away from students or anyone that she really would hurt.
