Hey all in going to attempt doing the 7th mission with low chaos today and had a question about the granny rags/slackjaw interaction towards the end. What's the easiest way to get this done? I'm not going for clean hands so a kill isn't out of the picture. Do I just kill slackjaw for granny and get the key or what? Any tips are appreciated. Thanks!

The easiest way is to start over from the very beginning of the game and not do any optional quests for Granny Rags or Slackjaw in the first two missions. Then you won't meet them in Mission 7, making it much easier.

Not an optional solution though, as you need to replay all the missions.
