I got as far as going to kematu and agreeing to help him capture saadia. But then I pick-pocketed a nearby Alik'r warrior for his hammerfell garb and scimitar which I wanted, got caught, and the whole cavern turned aggressive. I yielded several times to no effect, and tried casting harmony over and over but it doesn't effect them. So I ran out of the cavern thinking it was no big deal, kematu would still help at the stables. I told saadia to follow and then I went to the stables, but kematu attacks me on sight regardless. I backtracked to see if Saadia could go there first ahead of me and get caught, but she just lingers in white run endlessly.
So what do I do? My previous save point I can go back to before the cavern was like, yesterday. I've done way too much in that time to waste it all on a reset. I don't want to kill kematu and help saadia though either.
Any way around this?
I see your problem right there. You know they sell that garb in Solitude right?
I believe that all you can do is reload where you entered the cave to talk to him. Seems odd that you still have the dialog to trick her though, that is weird.
I know if OB you could wait like 3 days and aggression would reset on NPC's. Don't know if that works in Skyrim though.
