And then he learned why taunting Johto is a bad idea?

That's too simple. He'd want to I dunno, have someone leave snakes left in the lobby that crawl through the ductwork and somehow move the pillow over there while poisoning the IV at the same time or something.

Or send ninjas.

But since he doesn't have access to those, he'll probably tell whoever it is to do something like that. Or at the least, tell them to be creative.
