Spoileryou know Harry can learn 6 natural moves according to house rules. No need to forget one.
Also for a while I was going to say that someone should get Nada to put that corphish down but, no. I really want to see how this plays out. Will Rodriguez find a way to escape? Will he learn to love the trainer whose hand he now so intimately knows? Will some crazy antic result in him bumping into a pokéball, catching him for good?
My money is on Rodriguez never feeling safe un-fainting and Nada having corphish hand for the rest of our adventure.
