According to icon-uk:
Jason is more or less kidnapped by the aliens. One particularly psychopathic one, Seren, attempts to seduce him, then drugs him and tortures him in the crystal matrix thingie. When he's released from that the medical equipment they sue to check him out is also crystal based, hence the weird look to it.
The dark haired, black-on-black eyed cutie is D'mer, a member of the Resistance within the Empire, the one dressed like a psychadelic marching band just threw up on him is Rieken. It would appear that just about everyone in the Empire is bisexual, and D'Mer and Rieken go at it like bunnies every chance they get, Reiken and Seren also have a history which is so full of boinking that Liana has to start singing "Mary had a little lamb" very VERY loudly so she doesn't accidentally pick up on their memories of each other.
