Mmm, yeah, while not required, snipping the portion of the line in the hangar about “taking the throne” together could be good.
At that rate, you might as well scrub that whole line since Kylo already heard the whole “Kill me, and my spirit will pass into you” stuff. Not that he doesn’t want to kill Palpatine, but maybe he is aware of some way to defeat him without getting possessed (ie magical dyad powa).
The line replacement I liked went something like “Together, nothing will stand in our way.”
