When I fought Moseh I had Khur with me. The first time Khur tried to break free I said "No, don't do it!" and Moseh attacked my Strength. When Khur tried again he attacked my missile weapons. After the battle, I am pretty sure that nothing was reduced at all (not even leadership or anything). I did not have the repair Moseh quest. My InfilTRAITOR is a bit double agent, but has not done any real betrayal as yet. Perhaps the Vogel-as-double agent-fan theory has weight. Very often you can avoid outright betrayal, I think. My character has certainly not taken sides yet. If anything, I think an InfilTRAITOR should go Trakovite (weak on shaping).
