I know the feeling. He did that to me on 2 of my characters out of 4. I think he's bugged at times and it takes several reloads for him to behave normally. I was able to kill him very easily with 2 of my characters but had to work on him for hours on the other 2; cut scene after cutscene. Frustrating and annoying. This has nothing to do with not knowing to pull the levers (and when) or not knowing how to fight him.

Just ignore the moronic comments and keep reloading until he behaves.

I'd like to close by quoting Bellegar's famous last rhyme:

"Cursed be the mother that bred thee!
The wench must have been a hell-spawned banshee!"
