Question: Alfred comes up to Bruce who is examining print dust on the safe after his mother's necklace was stolen. Alfred says to him "This is your idea of sounding the alarm, is it?" What does he mean? I don't understand this line.
Chosen answer: The reason why Alfred says "This is your idea of sounding the alarm" is specifically because Bruce has not sounded the alarm. From Alfred's point of view, he has been told by Bruce that they have been robbed, but the only thing Bruce is doing is examine the safe for fingerprints. He found it odd that Bruce's idea of trying to find the culprit was looking for fingerprints and not actually sounding the alarm and having the place locked down so that they can find the burglar.
Question: When Officer Blake leaves Wayne Manor after telling Bruce Wayne that he knows he is Batman and that funding has stopped to the Smithens Boys' Home, Bruce asks Alfred "Have you run that name? Bane?" and Alfred responds with his findings. How did Bruce hear of Bane in the first place? Nowhere prior in the movie is Bane ever mentioned to Bruce. It's not mentioned by Selina Kyle, by Officer Blake and there is no news media mentioning anything. How did Bruce come-about asking Alfred to run Bane's name in the first place? (00:29:22)
Answer: Officer Blake does mention the name Bane to Bruce when visiting him (Blake says Gordon was babbling about an army and a masked man named Bane). That seemed to be his primary purpose coming over, to get Batman to help fight Bane. When Blake is at the door about to leave, the scene cuts to him outside walking to his car, so we don't know how much time passes. And while we don't see Alfred, it was possible he was listening. I don't know if there was a cut scene, but in the film it does seem there's meant to be enough time for Alfred to do a quick check on the name.
Answer: Officer Blake did in fact mention Bane to him, in the conversation that they just had. At the start of the conversation, Bruce asks "What can I do for you, officer", then Blake tells him Commissioner Gordon's been shot. After saying that, Blake says "He chased a gunman down into the sewers. When I pulled him out, he was babbling about an underground army. A masked man called Bane." That was how Bruce found out about Bane. (This line is said at 00:26:47).
Answer: He wanted to start a new life, which means shedding all aspects of his old one. Bruce Wayne was still a person of interest in the Gotham Wall Street scandal, with his death, his will would provide for and aid all the people affected by it.
