Hmmm… I do wonder if such advice coming from Kylo could be seen as a negative, though. If it was coming from Luke later on, then I’d be totally on board, but at this point in the movie we may want Rey to think her vision is inevitable, thus why she goes to Ahch-To in the first place.
But on the other hand, Kylo’s proposition to Rey doesn’t make sense unless he believes they have some level of control over their own fate. So maybe it’s better left unsaid that he believes this? I’ll have to think about this one a bit.
