Put her under and get some information

"Hypno... Hypno... Hypno..." He began to mutter in a monotone, his pendulum swinging as the woman slowly found herself going into a trance.

It was quick, clean, and easy. Her eyes dropped to a half-lidded appearance as her expression went blank.

Hypno couldn't talk - even as a psychic type he didn't have telepathy like some other pokemon. However, while he was using his pendulum on a human, he could convey his thoughts in some way. What he wanted to know was this woman's name.

"Delia... Ketchum..." She droned sleepily.

"Ketchum?" The Hypno thought. He knew that name from somewhere.

He thought back, recalling the bratty boy who was traveling with the redhead before. His name was Ketchum as well.

"I have... A son... Named Ash..." Delia added

That clinched it. This Delia woman truly was related to that boy. One of the crew responsible for his current situation... And he was going to have a bit of revenge on Ash by taking it out on his hypnotized mother.
