Ok I think I see what is happening, there was something wrong with the monocle. I went back to the graveyard and it was still there, so I grabbed it again and went to Alexander same issue. I tried a third time and a dialogue box popped up saying I got everything and I am able to see the H scene. I tried restarting the game and replicating the issue but the dilogue box pops up every time now. I think this might have been a weird one off issue that solved itself.
