Jango Fett mention in Star Wars: The Clone Wars

Prime Minister Almec speaking to Obi-Wan Kenobi about Jango Fett

With his death in “Star Wars, Episode II: Attack of the Clones”, Jango Fett does not get mentioned the entire first season of “Star Wars: The Clone Wars”, but finally gets mentioned in “The Mandalore Plot” (initially aired on 29 January 2010). When Obi-Wan Kenobi visits Mandalore, he inquires as to Jango Fett, with whom he had tangled in the movie, and this dialogue ensues between him and Prime Minister Almec:
Prime Minister Almec: “Master Kenobi, Mandalore’s violent past is behind us. All of our warriors were exiled to our moon, Concordia. They died out years ago.”
Obi-Wan Kenobi: “Hmm. Are you certain? I recently encountered a man who wore Mandalorian armor, Jango Fett.”
Almec: “Jango Fett was a common bounty hunter. How he acquired that armor is beyond me.”
What stands out is that Prime Minister Almec is quite defensive about Jango Fett being a Mandalorian. So much so that it seems very suspect. Consider that he says that “all of our warriors were exiled to our moon, Concordia” – which is true – and that “they died out years ago” is quite untrue. One wonders if he simply has no clue as to not only the continued existence of Death Watch and what’s going on on Concordia or if he is in on the ruse. Nevertheless, with his being out of touch of what was going on on Concordia, in general, and Death Watch, in particular, makes one doubt his assertion that Jango Fett “was a common bounty hunter.”
What does seem true about the brief interchange above is that Prime Minister Almec wants to believe that Mandalorians have totally abandoned their violent ways to the past and no one who is a Mandalorian would be violent. Thus, he says, there are no more Mandalorian warriors and Jango Fett was simply a bounty hunter who, somehow, found Mandalorian armor.
As far as “Star Wars: The Clone Wars” goes, it is unclear what Jango Fett’s relationship to Death Watch is….
