I've been revisiting Dishonored, and I am trying to see if there are different choices or results in some NPC scenarios. One such scenario would be the alley to the left of Clavering Boulevard in the High Overseer Campbell mission within the Distillery District.
In the alley, there are three thugs, two of which are arguing over how shares of loot are being split. I thought that I would try to defend one of them to see if I would be rewarded in some way, or if one of them would thank me and be on their way. I have defended both "sides" of this fight, but I always end up being attacked.
If there is a means of being thanked or rewarded, then I believe I am missing something else here. Are there any other outcomes, or can something come from saving one of the thugs?
