WARNING: The following contains spoilers for Star Wars: The Bad Batch Episode 3, "Replacements," streaming now on Disney+.
After fleeing Kamino in the opening episode of Star Wars: The Bad Batch and visiting Cut Lawquane in Episode 2, the show's latest entry, “Replacements,” sees Clone Force 99 stranded on a remote moon. However, back on Kamino, there is trouble. Now holding the rank of Governor, Tarkin and Vice-Admiral Rampart debut "Project War-Mantle," which could spell trouble for the Bad Batch and the Kaminoans. This new endeavor involves using specialized Clones to train and command conscription soldiers, and it will also cut costs for the Empire, which would spell disaster for the Kaminoans.
Knowing their survival is on the line if their Clones become obsolete, Lama Su, the prime minister of Kamino, and his chief medical officer, Nala Se, unveil the groundwork for a secret plan of their own. They are planning experiments that will create a “superior clone” as a way of maintaining their status as an essential business partner with the rapidly growing Empire. However, in order to do so, Nala Se needs "a direct source” to Jango Fett's DNA. But while she could be referring to Clone Force 99, there are a few other possibilities.
Clone Force 99
As the main protagonists of the show, Clone Force 99 could be who Nala Se wants for her experiments. Perhaps when she references needing a “direct source,” she meant that she needed a template of a previously enhanced clone. And with Crosshair heavily involved in Project War-Mantle, Nala Se probably thought it better to not use him for a covert operation, whether that was because they eventually wanted to use their “superior clones” as a rebellion force, or because they didn’t want to promise anything to Tarkin without being sure of success.
Boba Fett
Another option for the source is Boba Fett. While this could be a long shot, it actually makes the most sense of any possibility. When Nala Se references a “direct source,” that most likely means a clone with Jango Fett’s unaltered DNA. The problem is that the original material is rapidly degrading, and with Jango now dead, that is hard to come by. From that perspective, she wouldn't be referencing Clone Force 99, as they are defective and altered. She also couldn't be talking about regular Clones because Jango’s genome was altered to allow for greater docility and rapid growth. There is one loophole in the current canon, however. As part of Jango’s payment, he required one completely unaltered clone -- Boba Fett. That leaves the possibility open for Nala Se to try to bring the bounty hunter back to Kamino as a way of gaining a pure DNA sample.
Omega
The most likely option, though, is Omega. While the Kamonians claim her just to be another defective Clone, the fact that she isn't rapidly aging means it's possible she's unaltered, just like Boba. If this does end up being the case, it does raise the question of why Nala Se didn’t gain a sample from her years ago, but, of course, she probably didn’t expect Order 66 to turn the galaxy on its head and force Omega to go rouge with the rest of Clone Force 99
Created by Dave Filoni, Star Wars: The Bad Batch stars Dee Bradley Baker, Andrew Kishino and Ming-Na Wen. The second episode airs Friday on Disney+.
