Mazzy quest bug

Mazzy's quest just bugged out on me. Everything was find until I killed Baral but it didn't trigger Mazzy finding the antidote and Orsewell is trapped in a dialogue loop off saying he'll get him - the game acting like it's going to get him then back to him asking if he can help me.

Of course like an idiot the last time I saved was /before/ defeating a damn dragon. Could someone that's beaten the quest look at the globals and let me know what I need to put into shadowkeeper or the console to get the quest to finish. I really don't want to lose Mazzy (or beat the dragon again.)
