When watching SPECTRE, I couldn't help wonder how long Blofeld had been waiting for these events to happen. There must have been a temptation to reveal himself earlier than 9 years after the events of Casino Royale?
And where did he get all the photos from? Did he wait until Hinx failed to kill Bond on the train before putting up the photos in Bond and Madeline's rooms at his desert base? What if he had put them up beforehand but Hinx had killed Madeline? Can you imagine him telling one of his minions "You might as well take Madeline's photo of her with her dad out of room 218 now as she won't be joining us..."
The same thing with the photos of Le Chiffre, Silva and M on the walls of the old MI6 building - why take the time to do that? Just to taunt 007 some more? As soon as the desert base exploded, did he think of his MI6 building plan? Was it always plan B? I always like it when the villain gets annoyed by Bond's interference but Blofeld seemed to take it remarkably well, considering everything he'd ever done was because of how much he hated James. Even losing an eye! Surely that made him hate Bond even more?!
Indeed, there is a lot of taunting going on - "Cuckoo", and talk of Vesper - "She was the big one", and "your beloved M".
But Bond never shows that he cares too much about these things. I'd like to have seen Bond say "Yep, some of these things were bad, but I just got on with it". Surely that would have annoyed Blofeld?
