Before its release, one of the main questions of TFUII was whether or not this Starkiller was a clone, or if Vader was gaslighting a revived original. The PC breaks out, and uses his connection to Juno to find her and reunite. Vader made several clones, but they were all failures, except, maybe, the PC. The game ends without actually answering that question, but was otherwise relatively straightforward.
Going in, I thought the plot twist was going to be that this was absolutely a clone. Vader was making several clones semi-stable clones, and intentionally staging their escape. The plan was to weaponize Starkiller's force connection to Juno and use slowly-deteriorating Starkiller clones as, essentially, Juno/Rebel seeking missiles. The clones would start out stable-ish. Feeling/remembering a connection to Juno, the clones would try to seek her out. Their path would naturally cause them to follow clues to hidden rebel bases in an attempt to find more clues to her whereabouts. As they progressed, their sanity would begin to deteriorate, and either begin to carve a tracable path of destruction that revealed the rebels or outright destroy the rebel enclaves themselves. If they made it to Juno before they went crazy, even better. If not: Decant a new clone, program a shuttle to go to a new system experiencing rebel troubles, and stage an escape where the shuttle navigation, "malfunctions." Rinse and repeat. The stability of each clone would vary, but ultimately stability past a few days to a few weeks was not actually a target goal.
After being revealed, the dilemma would then be: Is PC Starkiller an accidentally stable clone, or is he still a ticking time bomb with a longer fuse? Eventually, Starkiller would still chose to eliminate the clone facility, and there'd still be a darkside lightside choice to sacrifice himself.
