 This attempt fails when external officers blow up the only bridge leading away from Gotham out of fear, since Bane had threatened earlier to have the bomb detonated (by a random citizen, later revealed to be Talia al Ghul, masquerading as Miranda Tate) if anyone tried to leave Gotham.After Batman apparently sacrifices himself to save the city, Blake quits the GCPD, disgusted that the mainland police were willing to let Gotham perish.He attends Bruce's funeral with Gordon, Alfred Pennyworth, and Lucius Fox.
