Where is the Move relearner in White 2?

Question

I've looked almost everywhere and I can't find him.

Answer 1

>Both the Move Reminder and Move Deleter were relocated to Pokémon World Tournament, south of Driftveil City. Her identification as the Move Reminder on the Town Map is the first time in canon the name has been used.

So yeah, south of Driftveil City. Go search around the PWT place.
