Shrapnel went through both of them as they ran. Up ahead she could see the entrance to the tunnels and the two girls fighting valiantly to keep it protected and out of view of their attackers. They were almost there when Lorna's panicked voice reached her ears. Kitty stopped running and turned to look at her, pulling the girl close in a sort of embrace as the wall beside them exploded and left nothing but the cold breeze of the winter night where a window used to be.
A mutant was advancing, something like a bug on Miracle Grow. She couldn't let it get to the tunnel or the students that were being ushered through it. "Lorna, everything is going to be all right. I'm sorry." Her apology was for her next action. She turned with the girl in her arms and then practically shoved her at the two older girls blocking the tunnel, breaking their contact. "Go!," she commanded the three of them. "I'll be right behind you!"
She turned, hoping Lorna would go with them and the rest of them would be safe.
