I don't know how humans would be able to do something as bad as all that.

[Sure, you could dump things into the ocean that would be poisonous for what lived there, but it's hard to dump enough of anything to kill a whole big section of it. And calling it corruption... it doesn't sound quite like good old pollution. And, besides, that long ago? People weren't really doing the kind of industry that even allowed for anything that poisonous to be made on that kind of scale.]

[But, hey, apparently men could turn into mermaids and vice versa, so maybe there's more things in heaven and earth than are dreamt of in his philosophy or whatever.]

I guess that's why you guys have so many rules about talking to humans, then? [If their history says that humans caused a catastrophe, than, well, it would make sense for them to forbid dealing with them anymore. Massive man-made horrors revokes your mermaid visitation privileges.]

I'm glad you aren't listening to the rules. [Gepard might otherwise be a very law-abiding mer, but if he had observed this particular law, than Sampo would've never seen him again after his rescue.] I promise I won't bring about any catastrophes!

[Probably. That he knows of.]
