The thought of 'Candon being creepier than Akemi' being something he has in common with Akemi is funny. If Candon were to abuse his position for blackmail, that would be a problem, but doing his job isn't 'lording it over' anyone. I don't think anyone on the crew has done or said anything in regards to Akemi that threatens the Star Army's reputation yet, though it's a serious possibility.
Even without them agreeing to make a porno or whatever, I can easily see Akemi leading them into a situation where all they can say is 'it's not what it looks like!', either intentionally (without really understanding the consequences) or by accident, especially if he's been open with others about what he's doing. I offered to have Tan accompany the others to 188604 as chaperone, partly for that reason. Mostly because I haven't done anything yet, and it's a good chance to RP Tan doing a little more 'field agent' stuff before she settles into being the ship's medic.
I expected Miria to be interrogated off-screen, with us only finding out the result later. Imprisonment seems a bit much, it's not a major leak. A letter of censure, revoked privileges, or a training course is what I'd guess, maybe a demotion if it would reduce her level of responsibility and access to records, it still seems a bit much to me if it's just as a punishment. I don't know how seriously the Star Army would take her association with Akemi, since I don't know how seriously they take Akemi, himself.
