Regarding “I’ll find you.” I get where you’re coming from, and I understand your intentions, but I kinda feel leaving it at just that is kind of awkward. (It’s a personal, subjective kinda thing, but… yeah.)
So I have a suggestion, replace the entire line with something along the lines of: “Rey, help me. Please.” I get the point of the original line, it’s to play into Rey’s fears of turning to the dark side, so I preserved that while also avoiding having Kylo Ren explicitly reveal his intentions of corrupting Rey. Here, Kylo is trying not to reveal his intentions, while also asking for her help against Palpatine, but Rey sees through it anyways.
