I really like the idea behind the “clone” line (I think we need an explicit confirmation of how Palps survived for the movie to make sense), and the AI voice is literally seamless. But still, I get why a few people are put off by the specific phrasing. In my opinion, it isn’t the presence of the word “clone” that makes it feel awkward, but how it’s used. Putting it at the end of the sentence just feels awkward somehow, like it doesn’t really flow poetically.

So, as an alternate suggestion, how about this:
“You’re a clone, in a rotting body.”

It’s just as terse and Kylo-esque as the original, and gets the clone info across just as well, but somehow just “feels” better to my ears. Your mileage may vary, though.
