Betty wasn't exaggerating when she said she'd had worse, so she eats the food without complaining out loud, and without fuss (but she does regret that her flight rations probably got lost in the crash. They would have been better than this).

She's a light sleeper by practice, and isn't about to get any when the doctor and nurse start their hushed whispering- furtive talk like that gets her attention more than anything else would - and when y e over in her direction she can hardly help herself.

She lifts a hand and waves.
