well, X-23 can take it. especially is she sees LDS. she will want them to get away. X-23 running isnt quite in her character for one, she also knows how dangerous LDS and the reavers  are pre-apoc steroids. If she runs with them, that whole mob will follow them until they get something. Laura can take punishment for her allies. she's played meatshield before, she'll do it again.
