"I don't know that I've ever heard of such a thing before," Obi-Wan says, thinking back to everything he's read about those who are Force sensitive and the presence they have within the Force. The only thing he can come up with is how the Sith believe in the power of two; one Master, one Apprentice.

But that isn't what Rey is describing. The Sith Master and Apprentice couldn't appear to one another, it was just a selfish and self-indulgent way of maintaining themselves as more important than others.

"That must be a very intense connection," he says.
