I just finished watching the movie again, and like the last time I has the same feeling. The feeling was that I was not fully understanding what the working relationship was between Bane and Talia. It seems easy to assume that because she had the detonator and the plan to seek revenge on Batman that she was the mastermind behind the whole thing, but if this was Nolan's intention I cannot completely convinced. My explanation is below but it's tl/dr for some, so just vote for what you think about their working relationship in the movie. Spoiler Bane had just as much fanatacism and conviction as she did, not to mention he had a small army of mercenaries at his disposal. She may have come up with the plans but Bane was the one who executed them without having anyone find out he was working with her. Meaning he probably figured out the way to do execute the plans. Plus when I look at both of them and the way they behave, I can't believe it was not Bane who wanted to blow up Gotham with a neutron bomb. He took it upon himself to personally put himself in jeopardy and beat the shit out of Batman. The dude seems like way more a psychopath willing to destroy a whole city than Talia. Just because he "loves her" doesn't mean that was his only intent.
