I finally got it, I believe it was some npc bug I do not know ... I spoke more than 40x followed by the cook until he talked about the pharmacologist and that worked. It was just that I talked to him uninterruptedly until I changed the text about Jensen.
Thank you all for your help.
Hello, I can not get HM Cut because the pokemon in the hall does not appear up the stairs. I've already talked to everyone and I've hurt everybody.
PS: Blue Server.
I need help, please.
