After being berated by M, Bond flies to Nassau and determines the identity of Ellipsis to be that of Alex Dimitrios ( Simon Abkarian) who, Bond learns by hacking into MI6's secure website using M's password, is an associate of Le Chiffre. Bond briefly returns to London, steals into M's private residence and uses her personal equipment to determine that the calls from Ellipsis originated from The Ocean Club in the Bahamas. Unfortunately, his escapade is photographed and printed in the newspapers, much to the fury of M. He kills an international bomb-maker seeking refuge at the Nambutu embassy and seizes his cellphone, discovering a number of calls from Ellipsis.

(Though it isn't specified in the film, Bond's mission right before Prague, where he made is first kill, took him to Pakistan.) On his next mission, 007 travels to Madagascar in search of the financier of a circle of terrorist groups. The movie opens in Prague (Czech Republic) in a flashback that shows Bond making his second kill, the event that earned him his 00 status. As for Casino Royale, it is very much a reboot creating a new continuity, and is not about someone assigned a code name. Bond is a single agent inhabiting a floating timeline, where he remains at one age while the world moves around him. (At any rate, the movie later has a scene where Bond reminisces about his former missions, something he couldn't do if he was a different person with a new code name.) Over the series, there are many scenes where Bond runs into old friends who recognize him as Bond, and in Skyfall we see the graves of Bond's parents, Andrew and Monique Bond. Many point to the opening scene of 'On Her Majesty's Secret Service' where George Lazenby as Bond says, as a girl runs away from him, 'This never happened to the other fellow,' but that was intended as a one-off joke to the audience about how it was a new actor in the role. It is never explicitly stated or even implied in the films that 'James Bond' is a code name, and there is little to nothing in the films to indicate the code name idea is valid. However, there is not in the novels at all, which are about an agent whose real name is James Bond. Some have even claimed that this is an idea from the novels.

Over the years, some fans have come up with the idea that there is no one 'James Bond,' that it's merely a code name assigned to a series of agents, as a way of explaining why Bond never seems to age and has continued for nearly half a century.
