I did some research and found out Anakin Skywalker will return in Episode 8. Hayden Christiansen who played Anakin Skywalkee in the prequels will return as a spirit to guide Rey and Kylo. Another rumor is that Snoke will take on the helmet of Darth Vader. Now this is the more interesting information on the concept of Anakin’s force ghost. It seems as if when Anakin died, he did not fully go completely light in the force. They explain how Anakin would flow back and forth between both Anakin Skywalker and Darth Vader. I am speculating that in Episode 8, we will see Anakin talking to Kylo Ren as Darth Vader, and talking to Rey as Anakin Skywalker. This concept is to good not to use. I am sure in the coming months we will find out if Hayden truly has been cast in Episode VIII, but until that time, speculate away!
