The OP doesn’t explicitly say that the diver in question was out of air, and I would be very surprised if she was.
Didn't read the entire thread but it appears that the OP's actual title to this thread explicitly states the OP's position that the diver in question was out of air. I would also be surprised if that was the case. More likely that the diver was low on air and sharing.
Thread Title: "Diver in travel group kept running out of air and sharing on every dive? "
