I first noticed them a few days ago when we left Lavender town. They kept their distance at first, but earlier one of them approached and Nemesis let them.

[Which, you know, for his fish is a huge accomplishment.]

I have no idea how she'd react to any other water pokemon coming near. I think having a school of Carvanha is making them keep their distance. She been-- I suppose I can't quite call it making friends yet, but she's been allowing Morgan near too. I've been trying to keep their encounters somewhat short as to not stress out either of them.
