Are these people even watching the show? (probably deliberately disingenuous)

Ake sits up and also wears shoes when things are serious. It a consistent visual cue. I’d be as mad as they were if cadets were dying and she were laying back in the chair just shrugging it off, but that’s not at all what is happening. Part of her character is that she is serious only to the extent the situation requires, and I think that casual attitude makes sense for someone who has been around for hundred’s of years.
