Carrie just sat. She'd taken a lecture from the doctors with a sour look on her face, but she hadn't spoken up. She didn't want to be kicked out.
When they were alone in the room and Juno seemed stable, Carrie sat back in her chair and wrapped her arms around herself. She was pretty sure the first thing she'd do when out of the room was get sick.
Until then, though, she needed to be cool and calm. So she closed her eyes and breathed like Bruce and Dick had told her to plenty of times before. So busy trying to keep herself centered, Carrie didn't notice when Juno started to wake.
