In the video Kylo Ren is without his signature mask, with Adam Driver's character growing an unkept beard. While entering Vader's castle, Luke appears to his nephew as a Force Ghost. He once again urges him to turn away from the Dark Side, and go return to Carrie Fisher's General Leia. Unfortunately he turns away, and we meet another iconic Star Wars character, this time through a hologram.
