Sara watched Marc be with Benjamin, but could see his expression wasn't one of happiness. She tossed up the idea of interacting them but she wasn't sure she really wanted to right now.
Her body felt heavy and her head hurt. She walked over to get a glass of water to herself, they wouldn't give her painkillers if she asked; they would be afraid she'd give them to someone else that would have abused them in the past, or they'd interact incorrectly with her system.

Sara was sure they laced the water with something, it always tasted gross to her. It never tasted clean, or at least not in the common room. It was less flakey in the staff rooms, but no one really wanted her there.

There was a moment where she looked back to Marc and Benjamin, she sighed and hung her head as she moved to take a seat on a chair nearby, but she didn't feel like interrupting anything.
That and if Marc wanted to talk to her, after what she did, he'd come to see her rather than her ruining things more.
