I said he 'tried' to teach me, not that he was successful. He sent me recipes all the time.

[For some reason, just talking about Kirikou helps. She knows he has a perfectly fine life he's gone back to, but she's also very aware that he'll never call her in the middle of the night just to chat again. It's strange, how much that bothers her.]

The other Pokemon he left to me...it's his Clefairy he taught to cook. I think that was on purpose.
