2. Bruce Learns A Key Bit Of True Exposition From A Vision
With sights set on rounding off the trilogy, Nolan made a smart move in bringing back Liam Neeson to play Ras Al Ghul; it gave the whole League Of Shadows plot some legitimacy that wouldn't have been attained with just lip service to the character. With Scarecrow alive, Joker respectfully retired and Harvey Dent directly tied in to (some of) the films set up, Ras was the hardest to deal with. Hes such a presence in the plot and yet showing any footage of him in a new flashback would feel forced. A pain/dehydration induced vision, however, surprisingly works. Except that its not only used to pay tribute to the character, but deliver a key plot point too. Bruce has already heard the story of the mercenarys child and wrongly assumed it was Bane. Now hes having visions of long dead people who tell him true exposition out of the blue; the child may not be Banes, but it certainly is certainly an Al Ghul. Theres no other way Bruce could have heard this (if the doctor said it, why not show it) and yet he takes this vision (including Ras non-plussed response that Bane is his son) as truth.
