Psychic moves tutor

I looked at the wiki and it says that s/he is in Hekate town in the front of the pokecenter, but I can’t find him/her anywhere (looked all around the city) I also searched the forums, but I couldn’t find anything. I want to teach zen headbutt to my Mew, anyone that knows where s/he is?

She’s not there for me :confused:

EDIT: Okay so she just suddenly appeared after I went back and forth in the teleporters.
