People seem to go back and forth on how (or if) Fett is alive and will be in the series. I’m not up on most EU or any Lucas SE whatever-the-fucks. Is there any real reason to assume he lived beyond ROTJ?
Yeah, the cameo character at the end of the episode was played by Temuera Morrison, who played Jango Fett in Episode 2. In case you’ve cleansed the prequels from your mind: Boba Fett is a clone of Jango Fett, and was raised as Jango’s son for about 10 years, until Mace Windu beheaded Jango in Episode 2 (then in The Clone Wars animated series, we see young Boba attempt to blow up Mace, and generally come into his own as a young bounty hunter.). So there’s a 99% chance that the guy who a) looks just like Jango Fett, b) showed up on the tail of the guy currently in possession of Boba’s armour, and c) is on the planet where we last saw Boba Fett, is Boba Fett. There’s a slim chance it could be one of the million other Jango Fett clones, like Cody or Rex, though.
