Keep it. Whack your thing in the head with it, it might make him a little smarter.

[Ulterior motive, what ulterior motive. Besides, TM27's well suited to this kind of thing - reasonably cheap as TMs go, any Pokemon can learn it, and Return works based on friendship — so the better she gets along with the thing, the better it'll be at helping her out in exchange. Not half bad.

Also, unlike her critter's existing movepool, it'll actually hit some damn Normal types.]

Or it might not. I've never used one before.
