"I've given him some sedation" the doctor is heard to reply.
Well either the doctor is a blithering idiot....or he's simply following orders, possibly the latter. Because that's not the Professor lying in his bed, and the Prisoner quickly picked up on that fact. It might look like the Professor, but it isn't, and what's more the doctor knows it, but still he and his nurse go through the motions of looking after the Professor's well being. But for whose benefit? Surely not for Madam Professor, seeing as it was she who made that wax effigy of her husband's head. And yet there was the puzzled look on Madam Professor's face, as though she didn't understand what was happening, as No.6 passed a piece of her husband's face to her, saying she should take greater care of her husband.
“He’s gone to pieces!”
No.6 who was about to bring down that walking stick onto the Professor's head, knew that it wasn’t the Professor. So surely Madam Professor must have also known that wasn’t her husband lying in the bed! When I have watched the scene I have often wondered why it is that madam Professor screams, who or what she screams for? Her husband, or her masterpiece that No.6 is about to ruin, did ruin in fact.
“Ah my dear, he seems to have made a bit of a mess of your masterpiece” No.2 tells her.
So madam Professor had made that wax effigy of her husband's head. So why feign her reaction as though she had no idea of what was going on, was it simply for the Prisoner’s benefit? This is one of those situations in the Prisoner when the viewer isn't sure what's going on. But in this case, I'm not sure that madam Professor does either!
