While he had had to endure a demon's attempt to bully him in order to experience this, Castiel had to admit that it was satisfying to watch Ruby be disciplined by a human soldier. If she had any of her power left in her, it clearly wasn't enough to manifest now. That seemed to be a common factor for all patients during the day, however. It was at night that he would need to watch himself.

These soldiers were more serious with punishments than the nurses, however. While the officer hadn't taken out a needle to sedate Ruby, she nonetheless gave her a full report of what she would have to do for the rest of the day. Or rather, of what she couldn't do. It wasn't all that severe from an angel's perspective; Castiel had endured punishments far worse while serving Heaven. Despite that, he got the feeling that it would bother Ruby. She'd been behaving rather childishly since she'd lost her temper, after all.

In this situation, he knew that the best thing to do was keep quiet. He caught the look from the soldier and understood its meaning completely. If anything, his posture stiffened in response. He wasn't a mindless soldier anymore, but he could still play the part if it kept him out of trouble. There was no reason to get on the bad side of the military here. If anything, that would make his job harder, and it was already hard enough.
