[Law's getting in the water (normally, he's not jumping in because he's incapable of letting loose.]the moment the confirmation is given, though he doesn't even get a chance to fully submerge before he's hit with a weirdly specific question. He fixes Molly with a quizzical look, but he's snarp enough to reason that this is rooted in some strange personal experience Molly's witness back home. Or maybe here? Who knows.]

That's not the issue, no.
[He pauses, deciding on how much exactly he's willing to tell Mollymauk. So far he seems like a guy who's suspect in a harmless sort of way, and he seems to like Law for whatever reason. Still, if he can avoid people knowing his critical weakness here, where it's common knowledge back home, he should, right?

On the other hand, if Molly's going to be on his boat, it's probably necessary information for him to know, isn't it. And if he just settled on "my powers don't work in salt water" that'd raise the question of why he'd need them at this moment.]

... The drawback of obtaining an ability like mine is you lose all your strength when you're in contact seawater. I can't use my ability or even swim in it.
[This is already weird, but surely weirder in the face of him being a pirate.]
