also, wasn’t the point of connecting their minds, to trick Rey into coming to him? finding luke from Rey was just a part 2 of the plan, not the whole plan. Rey was someone to be dealt with on her own based on her force use in TFA, snoke knew this.
Yeah, but why trick Rey to come to him, if he can send an armada to come to them, and get both Rey and Luke?
this is again your thinking though. no evidence that he knows where they are!
No, but he should know. He can link their minds, get Kylo to read Rey’s mind to see hidden memories of her parents, get them to see each other, and touch each other, so he should be able to read her mind and get the information about their location. If he can make Rey and Kylo touch each other, he should be able to touch her himself, and choke the life out of her.
I don’t know, maybe he just likes to screw with their minds.
