What happens if Slackjaw is killed in Mission 3?

For the heck of it, after playing through Dishonored with a (nearly) no-kill philosophy, I started a second playthrough of the game, being as ridiculously violent as possible. Therefore, when I got to the Distillery, I cut down all the thugs, including Slackjaw. Apparently that's possible.

This begs the question... what's going to happen in Mission 7? He's supposed to show up as Granny Rags' prisoner. Does anybody know if the game takes this into account?
