If you run out to where Blightghast stands usually, he might reappear. You can give him a quick slap with your weapon, then run back toward the boat you came from and the story should resume as normal. This happened while I was helping my wife get through her personal story a few days ago.
We waited a good five minutes for him to show, when she walked out to where he landed in the cinematic he sort of just popped into existence.
