The Book of Boba Fett skipped over how the title character got his armor back, which was an event explored by The Mandalorian. Ahead of his starring role in Star Wars’ second live-action show, Temuera Morrison’s Boba Fett factored heavily into the story for The Mandalorian season 2. It was during his encounter with Mando (Pedro Pascal) that he recovered Jango Fett’s prized beskar armor.
The flashback story in Boba Fett’s Disney+ series, which seemingly came to an end with episode 4, revealed quite a bit about what the bounty hunter has been up to since his “death” in Return of the Jedi. In four episodes, the show has answered several questions, the biggest of which being how he escaped from the Sarlacc pit. As for how he spent his time, it’s now known that he lived among the Tusken Raiders, who made him a full-fledged member of their tribe. In The Book of Boba Fett episode 4, the series told the story of how he acquired the ship. And though it did explore his efforts to recover his lost armor as well, it didn’t show him actually finding it.
The retrieval of his armor was covered extensively in The Mandalorian season 2, which explained what happened to it after the Jawas stripped it from Boba Fett’s body. Apparently, it was purchased from the Jawas by Cobb Vanth (Timothy Olyphant), the marshal of Mos Pelgo. It was still in his possession when he crossed paths with Mando in the season 2 premiere. After receiving some help from the Mandalorian with a problem, he willingly handed over Jango Fett’s armor, with both characters completely unaware of its history.. As for how Boba Fett knew it was given to Mando, that can be attributed to the end of the premiere, which showed him observing the two on Tatooine. Obviously, he went to the Jawas and tracked down Cobb Vanth offscreen.
Due to his years of experience as a bounty hunter, Boba Fett and Fennec managed to quietly follow Mando to Tython, where they met for the first time. Their conversation about who the armor rightfully belonged to was cut short when Moff Gideon’s forces arrived to take Baby Yoda away. Having been caught in Mando’s battle with the villain’s army, Boba Fett seized his chance and suited up during the fight to help beat their enemies. Because his assistance was necessary for their survival, he received no resistance from Mando on keeping the armor.
Getting his hands on the armor was the penultimate step toward setting up his position as the daimyo of Mos Espa and the current ruler of Jabba the Hutt’s empire. The last, which was Boba Fett killing Bib Fortuna and taking the throne for himself, was also featured in The Mandalorian season 2, which means that the Star Wars franchise has no more gaps left to fill. So after The Book of Boba Fett episode 4, the series can now look forward rather than back by focusing its attention on his plan to maintain order in Mos Espa and defeat the Pyke Syndicate.
