So I collected the hat, monocle, and pipe. When I go to the lizard man he is already wearing them and when I talk to him he asks me if I collected them all and reminds where they might be. Am I missing something? Should I load a earlier save? I got the monocle from the graveyard, the pipe from the surfing game, and the hat from the city. Not sure what to do now. 

That should open the dialogue box to start his H scene. I'm not entirely sure what may have transpired here. Can you give me more details? There might be a rare issue, and uncovering that would be something I want to do.

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. 

it seemes this bug is arising again a have collected all 3 objects but the dialoge box is not showing i'v been looking again for it after reading this post but not a chance
