Can he be romanced?
It's already been released, Pale Angel! When you get thrown in the Brig by the Constable, you're given 3 choices of cellmate: Rydick, Krathi or Luke [or none of the above]. Each has a big sex scene, but Rydick has the extra backstory sequence.
Although that gets pretty rough, there is no requirement for CBT, SPH, of anything like that 😁
Whatever happens, you end up being thrown in the Brig [either you are caught trying to rescue Anna, or 'messing around' with Chad]. The Constable and Meera Munipanni give you a choice of one of 3 cells [or to wait in the interrogation room and skip the cell sequence entirely]. The occupants of those cells are Luke [the skinny power-bottom cadet], Krathi [the aggressive female warrior alien], or Rydick [the dom mercenary]. If you go in with Rydick, make sure you look into his eyes!
