Okay. Rise of Skywalker is a walking pile of dog shit that has a wildly inconsistent take on everything. However. I have never had a single problem with that line and I am stunned so many people did. That was a rebel talking to other rebels. Why, exactly, would they know anything about how Palpatine returned? Dude was on a planet out in the middle of uncharted space. I literally cannot think of another way for them to tell each other that Palpatine returned without evoking vague imagery like that. They literally do not know what happened.
