Bleh. If you guys are referring to the ragged up ID-SOL Anselm managed to capture and not maim or kill, he's just a junkie hired by a rival gang to kill the two members in the bar (one of which is disposed by Phaedra). You could drag him back, but since Fian isn't at the shuttle, Ran would have to deal with it. There wasn't any important plot events during the previous shore leaves. We could have done something new, but, I wasn't around during that time.
EDIT: On second thoughts, it could be a conspiracy but hey, what would a brain damaged ID-SOL know?
