@Neo Emolga I don't think there'd need to be a complete wipe of all that, it shouldn't be too hard to adjust what happened so that Nathan doesn't actually hear any words. Just having the ninetales react unexpectedly, overly vicious to having the tale grabbed should be enough, given the proper re-wording. In your post in response to mine your NPC characters claimed they ran into a psychic that could control emotion, so it's not that hard for me to get rid of the "You're not welcome, go back" quote and just have gardevoir force fear upon them.

As for the actual transformation it may take a little work, but the ninetales could still transform Nathan and explain what happened after he'd been transformed (since they'd both be pokemon at that point) I myself need to go back to my first post and change the dialogue between gardevoir and Leo to feelings/emotions but that shouldn't bee that hard.
