Luke is talking to Rey when he is saying its not going to go how you think its going to.
Kilo tries to persuede Rey to join him but I think she will rebuff him again.

I was thinking kind of the opposite, that the moment where she cracks the rock takes place well into the training and is a breakthrough by Rey.

I also have a feeling that the this isn't going to go how you think, and its just a my theory is that something happens where Kylo does something particularly bad and Rey decides to abandon her training and go after him, ala Empire Strikes back, but this time unlike where Luke escapes Vader, Rey doesn't escape Kylo and gets taken before Snoke ala Return of the Jedi where she is tempted by the Dark Side and Snoke who also feels her immense power.

The really wacky theory that I've been reading is that we get a double turn, Kylo is trying to save Rey from Temptation in that scene in the trailer, and Rey rebuffs him and we get a Kylo to the good side, Rey to the bad side, and Skywalker as the big bad wanting to wipe out the Jedi, and Snoke gets thrown into a reactor way early
