He does not need a mom, but he will in fact need severe medical attention once he arrives. He's coming from a literally mortal wound dealt to him because I need to side-line Dean while I go on vacation. It would be handwaved at first, but would Claire try and do her best to help and at least get him patched up enough to board the train with everyone... He needs... INTENSE triage.

Addie is also a doctor, too, so I'm not opposed to the two of them helping him out.
