Due to popular consent (and, by that, I mean CJ and Chewy), I involved Dr. McGregor in the story. Use him. Don't use him. It's up to you. I figured he could go with the body back to the MRC for a proper autopsy.
As for the attacker, I have no plans. Thought it might be fun to give the fighters something to do while Adem and Ian go about the investigation/examination. I don't have a name for her. Give her something with a 'tribal warfare' feel, as she should be an Anti-Lykopis character. Super-strong-female warrior from an obvious African tribe. Play with it. Or don't. It's up to everyone....
