Nothing wrong with getting naked in your own room, behind closed doors.

[ Apollo gestures pointedly at the space where Kovacs' door had once stood. ]

You don't have a door. Literally anybody can see you right now! There are teenagers on board, for God's sake...

[ Apollo gives Kovacs a look, determinedly meeting his eyes and not an inch further down, and archly adds: ]

If any of us wanted to see you naked, we'd tell you. [ He won't. ] Until then, keep it where we can't see it.
