Kylo takes part in an ancient Force ritual where he takes the role of ‘Vessel’. he is reverently made up and adorned with jewels and sweet smelling oils by the knights of Ren. He is then placed on an altar waiting for whomever the Knights have chosen to ‘fill the vessel’ as it were. To his surprise Hux shows up. And Hux… well mark him down as equally surprised bur also weirded out and horny!
