What was the last thing you did? Talk with the landlord?
No, I met Judith out the front of the house and joined up with her. Quick sidenote, in my experimentation trying to figure this out, I tried on a new costume to see if that would trigger something, and in doing so found that switching outfits puts any companion that is following you as the lead; as in I was piloting Judith with Nora in tow, when until then it had been the other way around. Not really important, but thought it was worth a note. Cheers for the response Mr. Bladegames
