cant distract the nurse. i've checked the sewer, got the hammer as well as the syringe. but samuel keep saying there is nothing to talk about. please help
Have you tried going back and talking to the nurse and boilerman again? Sometimes you have to talk to people several times before they say everything. Also, have you checked out both parts of the graveyard behind the Sanitarium...
Just to add - try to enter the grilled gate to the left of the nurse's station and see that you can't go through. That might give Samuel ideas to try another ruse.
