When I read your idea about Kylo losing his connection with the Force, I thought that was a pretty clever way to have Kylo atone as well as not making the hero team to overpowered by having the last two force users on the same team. But I had not even considered how that would effect his force bond with Rey, and if it would effect her abilities. At first I thought it might enhance Rey’s abilities to the point where she can barely control it, but I also like the idea that they both have lost their connection to the Force. The backstory in the Jedi Texts is pretty interesting, and it sets up an interesting dilemma for both Rey and Ben now that they must try to work together to reestablish that connection, possibly.
