The OP doesn’t explicitly say that the diver in question was out of air, and I would be very surprised if she was. I’ll go out on a limb and speculate that she was low on air, maybe had hit the agreed ascent pressure (even novice divers in a recreational group have one) and wanted to stay down longer. Maybe she didn’t want to force the others in the group to ascend early, who knows. IF that’s an accurate description, then it’s a little sketchy, especially for a new diver, but not an immediate emergency. I would also assume that she had agreed with the donors before the dive to possibly share air. If she’s surprising people asking or air, that’s getting sketchier. One issue is ascent rate, safety stop length, basically controlling the profile, but I suspect those concerns were probably beyond this diver.
Obviously, if she was really out of air then it’s a very bad, dangerous practice, but it doesn’t make sense that anyone would tolerate such behavior repeatedly on a group dive trip.
