Alright, she isn't making off with the shells... though whether or not that's because she simply isn't interested, or because he has chosen undesirable ones isn't clear to Glacius. Or perhaps she is simply more occupied with looking for him, which would make sense given his strange form and sudden disappearance. At least she's not being overly aggressive about it, which helps the alien think his previous alarm might have been unfounded.

Only might have been, though; he isn't sold yet, not when she just came running at him with a weapon. So he forms just enough of himself form the water that his gills and vocal chords manifest, head and the upper portion of his neck elevated above the surface of the ocean, and calls out to her, "Do not shoot; I've no interest in a scuffle. Put that weapon away and then we can talk, if that is what you wish."
