[Alex]

Spoiler:

No, it was all plan. He had explosives set in a specific room. He had a very specific moment planned for when he'd assassinate M. All of required knowing, before he was captured the exact moment he'd escape from MI6. He had two fake cops in a tube station set to hand him his disguise at a specific moment in time. he had a car waiting at a specific spot at a specific moment to take him to parliament.

All of this ha to have been planned before he was captured since he never communicated with anybody after that. And not just knowing that he would be captured but exactly when he'd be captured because everything about the latter half of the plan was extremely time specific.

And to know when he'd be captured with such specificity he'd have to have even manipulating Bond (or whatever agent ended up on his tail) from the beginning.

Now, perhaps he didn't know Bond was alive, but ten the curious question would be why Silva waited months after capturing the drive to begin phase two of humiliating M before killing her.

The problem beyond excessive villainous omniscience is that the events make even less sense without it.
