No but I thought I'd read an earlier report they went from the resturant to the dive shop but didn't rent any gear there. (but you know how reliable stories are here, not.)
I know anythings possible but if she had gear on, mask, snorkle, fins it would not be too likely to cut your foot in the water.
Signatures look very different to my eye also, one had some backward looping, the other had none of it. Even at that I don't think he'll collect but he may file a lawsuit to try, I'd like to also see a known signature of RG's also.
I'd really like to see the footage they supposedly have of them arguing in the hotel lobby.
