Mostly its her barriers -- but because we're in the weird KK-Acceptance-Self-Transcendence part of her heart they will go if you do a bit of work. Water in general is protection and centering and healing and there is a lot of her Self tied up in that. It's also a big part of 'death' for her. (And 'life'). So it'll show up allllll through out her heart. Symbolically.

I guess I should say if someone she didn't like or trust went a swimming they would probably not get the sea to part for them. But if KK did it would be quite easy :B
