Well, lol, it seems that a generous interpretation is (1). So, suppose that is the case. What are the real problems with allowing him to reschedule with the nurses? Could it work if you reserved veto power? If so, this would be generous of you to allow. But, if the problems (like, I'm guessing, the nurses feeling hassled if nothing else) outweigh the possible benefits, then I don't see any reason to offer to accommodate his wishes.
And, of course, let him ask, through a lawyer, first. Otherwise, don't worry your pretty head about it. It has better things to do :-)
