Bond Continuity Theory: Bond and Blofeld not recognising each other in OHMSS is not a plot hole
I have some theories to share which you might find interesting about the continuity in the Bond films. I will start with the supposed plot hole in OHMSS when Bond first meets Blofeld and they fail to recognise each other. A lot of people don't like this about the film as they believe it doesn't make sense. However I believe that it is an example of clever writing and acting. Here we go:
Bond is definitely hunting Blofeld following the events of YOLT. 2 years have passed as M says early on in the film. When Bond travels to Piz Gloria, he is unarmed and gadget free. He is immediately sent for a medical examination so one can assume he is strip-searched during the examination meaning somebody can examine his clothes. Also Irma Bunt says to one of the assistants after Bond first gets in the elevator "you have ten minutes, then take them to number 8". We can assume that the guy is going to search Bond's luggage for any weapons or gadgets. Bond of course has no objections as such because he is completely gadget and weapon free as he pretending to be Sir Hilary Bray. Again, to reiterate Bond has been trying to hunt down Blofeld for 2 years so this is his first chance in a long time to get to him. Bond also has the blond guy for backup anyway remember.
Blofeld has not seen Bond so far and all reports from Bunt and staff are all satisfactory. His glasses and pipe are simple adequate cover. Therefore Blofeld eventually requests Bond be sent to him. Take a look at Bond's face when Bunt announces that he will meet with the Count. He looks a little worried (maybe because he isn't wearing anything to cover his face). Bond is taken down to the office to meet Blofeld. Just think about Bond's situation for a moment. Bond can do nothing if Blofeld recognises him. He has no weapon, no clue as to what he is up to and no quick escape. Blofeld walks through the glass doors to greet Bond. Take a look at his face. It looks as though there is a glint of recognition in his face when he sees Bond. Remember Bond was supposed to look "Japanese" in the end of YOLT so maybe Bond's face does look considerably different to Blofeld. I think though when Blofeld shakes Bond's hand, he knows he is Bond immediately but is completely surprised at this fact considering Bond travelled all that way under cover and weaponless.
But what can Blofeld do? If he attacks him , that risks his lab research being destroyed and Bond is maybe reporting to somebody so killing him would lead to suspicion from the outside world just like Goldfinger’s decision at the laser table. Bond pretends to be Sir Hilary Bray as that is his only safe option in the situation at the time. Blofeld pretends to not recoqnize Bond as to try and counter-think Bond. But then Blofeld suddenly turns on the lights in his office and Bond's face shifts nervously. I think Blofeld wants to show off his considerable face change (probably due to plastic surgery) as well as his new ears while at the same confirm his suspicion that he really is facing Bond.
Bond then drops the clanger about the de Blauchamp family which, when he does, you can see the anger reflected in Blofeld's eyes knowing that he really is Bond and can do nothing at the moment to deal with him. Bond’s posture in the office looks like he’s been rumbled. Blofeld then lets Bond go back to his room, to allow himself to think about what to do. Bond proceeds to do research in his room then sneaks out and goes to Ruby’s room. Somebody must be monitoring the doors using some form of computer system because Blofeld's team must know that Bond leaves his room. They must then notice that he goes into Ruby’s room immediately afterwards and so does nothing. They don’t want to alert Bond to anything, and also disturbing Ruby will also cost Blofeld time and money. So they must wait for him to leave the room but of course the other girl is there waiting in Bond's room. They probably don’t want to disturb her as well so they leave Bond alone that night. Of course they know Bond will try and do the same thing the next night so that is why Bunt and company set up the trap in Ruby’s room waiting for Bond. Bunt also asks Bond in the morning ‘Is the stiffness gone from last night?’ implying that she knows he was out of his room the night before.
So what you have everyone is actually a cleverly written scene which depicts the actions of two characters trying to behave normally even though both of their identities have been blown. In my opinion it is definitely NOT a plot hole.
