I can only fathom... [There's a part of her that's saying the alternate universes for two people isn't a subject she'd want to get too into. Not unless she wants a headache.]

Hmm. That makes sense. A Pokemon who changes elements needs to adjust to not only the type of body they have, but also the new element they obtain through evolution. Sorta like how a mage needs to get used to the differences between how to cast a fire spell and a lightning spell. Though without the form change.

[If someone wanted her to change right away she'd just walk right on out of there! But looking at the situation with Pokemon...] Yeah, changing immediately wouldn't be all that fun. So I can see where you're coming from with that.

I'm not surprised that they would be expensive, considering what they do.
