Tull's Escape

http://www.uesp.net/wiki/Morrowind:Tul%27s_Escape

If you choose to help Tul (the Argonian) escape from the Dren Plantation (and I also chose to mention the Twin Lamps before escorting Tul to the destination): 

The quest seems to proceed as normal until Journal index 60.  It appears that the quest completes before you choose to either walk away or stay and fight.   No matter what you choose the quest completed at Journal index 70.  Tul's dialogue matches your choice however, in both cases he walks away, and does not attack Sterdecan (the Redguard) or the player.  Also Sterdecan seems oblivious to the whole thing and does not offer any dialogue related to the quest.  Although Tul's disposition seems to drop if you choose to stay and fight because his dialogue is like 'Leave me alone!' or 'Can't you find someone else to bother?' etc.  and he won't even stop to talk to you, but if you chose to walk away he will stop to talk to you after.
