Now that Cad Bane has showed up it seems very likely to me that the Fett vs Cane story-arc might be repurposed for this series. I haven’t read up on the details of the unfinished episode(s) but I would assume they wouldn’t have to change too much lore-wise.
From what I recall, the unfinished Bounty Hunter arc had Bane and Boba team up to rescue a child kidnapped by Tusken Raiders. Then Bane and Boba later duel over some ethical dilemma, I think Boba was leading a town insurrection for some reason on Tatooine. I doubt much of this being carried over to Bad Batch, but I would LOVE if we got that Boba vs Bane stand-off.
I actually think Bane’s duel with Hunter sets it up. The audience is reintroduced to the audience as a formidable duelist. Bane saying, “I’ve taken down so many clones over the years. Once you figure out one, the rest are easy” would be a great set-up for a duel with another clone: Boba.
With the War of the Bounty Hunters arc going on in the comics right now, it almost feels like we could get a similar “war” between bounty hunters over Omega. At the very least, I could see Boba dueling Cad Bane for money or moral reasons. I would be so stoked if we get to hear Cade Bane say in his signature voice, “It’s just you and me now, Boba Fett.”
Speaking of War of the Bounty Hunters, I know it has been compared a lot to Shadows of the Empire since it is covering Boba’s struggle to get Han to Jabba and the general events between ESB and ROTJ, but I kinda see another similarity too. Although it isn’t exactly the same, I feel like we’re basically getting a multimedia exploration into the life of Boba Fett.
War of the Bounty Hunters covers what Boba was up to in-between his two OT appearances. The Book of Boba Fett seems to be exploring different parts of his life, like what happened to him after ROTJ, and then what he is doing after Mando Season 2. If we do end up seeing Boba in the Bad Batch, we could possibly see a snippet of him becoming that feared bounty hunter we first met in the OT.
