Well, I suppose this is why as a husband, you need to strive to be on the 'same page' as your wife so that you don't lose her to some...Hypnosis stuff.
I'm not sure if her not remembering it makes it worse or not. Probably worse, since she's getting changed without realising it and her husband has no way of knowing because she can't...well, 'slip up' in any way.
Makes me wonder if her friend is actually in on the whole deal, or is just another victim.
