Padme watches the screen transfixed at first. Well... it wouldn't be the first time that she'd been right at death's door. Now question of the matter was surviving it. Eventually she walked over back to where she'd been before and just closes her eyes allowing herself to fall into a meditative state again. She's not running anywhere. And if and when the Doctor returns and she's not moving its because of the meditative state not because of something more terrible.
