Pavel was kept as a hostage for six months, as the prologue (the plane heist) takes place six months before Bane enacts his plan in Gotham (confirmed in dialogue by Talia when Bruce shows the reactor to her). The bomb then goes off five months after that.
Nobody captured Bane for the plane heist. The whole thing was a setup orchestrated by Bane, to get him on the plane with Dr. Pavel so they could extract him. The person driving the car (carrying Bane and the other hooded thugs) was Barsad, Bane's right-hand man.
Bane was rejected by the League of Shadows by Ra's al Ghul, before "Batman Begins." This movie, "The Dark Knight Rises," takes place 9 years after "Batman Begins."
After Batman defeats Ra's, it's perfectly conceivable that the League of Shadows was in shambles, and that Bane and Talia went back to the League to take over the leadership in the resulting power vacuum.
It's also perfectly conceivable that Bane wasn't actually leading the League, and that he just claimed to for his own purposes.
It's also perfectly conceivable that he made his own, new "League of Shadows," now that the original, Ra's-League had been defeated.
Both of these latter two theories jive with the fact that Bane's methods seem a bit more blatant and roundabout than typical League methods.
Who was the guy on the plane that they took blood from, and why did they put blood into Dr. Pavel? Then there was another guy that asked Bane something about the fire rising. What was the deal with that guy?
I think they could have explained where Pavel was by showing him in the scene where Gordon is taken into the sewers.
Also did Bane ever do anything for fun in his spare time? He had a lot of time to kill in the sewers and doing stuff with the League of Shadows. And that mask, did he ever take it off and wash it and his face? Because that would suck if he didn't. Yes I know the mask holds his pain at bay, but he also would need to wash his face and the mask every two weeks as well as shave.
