Keru hasn't been a monk. There have been references here and there to him showing interest in another crewmember (for instance, the end of Sword of Damocles implies he's having a romantic rendezvous with someone, though the gentleman is not identified by name), though nobody's gotten around to developing that thread in detail.
I apparently missed that entirely. Guess I need to go back and re-read it. I just remembered his utter disinterest in Ensign Norellis, and since Norellis left the ship after Destiny
, I know that wasn't going to go any farther. I think I remember Andy Mangels saying that Titan
's transporter chief was supposed to be gay too, but that it didn't make it into the narrative.
Anyway, thank both of you for the heads up.
