The picture of the FA in the LH seat-no "sad but true," and no "control."
Captain leaves the seat for the loo, comes back and she starts to get up. He says, no stay there a bit, I will stretch my legs and stand a bit. Takes out his phone and takes a picture.
She can happily show the picture and they have a little light time. No danger, no implications, in cruise, in good weather and for all we know, the FO is in fact also captain rated.
If something did happen, she would be out of the seat in no time and there would be no difference from him going off to the loo and no one sitting in the seat.
Happens all the time stiff-necks..........
