Obi-Wan is pulled from his sleep by a feeling of unease. He lays perfectly still, searching for what disturbed him. A moment later, the figure beside him gasps and jerks just slightly. If he had still been sleeping, he might not have even noticed it; Padmé is far too good at controlling herself for his peace of mind, sometimes.

As she slowly leaves the bed, he debates how he should act. He could let her go, let her believe she didn't disturb him, that her nightmare went unnoticed. He wasn't going to leave her alone, uncomforted, but he could wait a few moments, before getting up himself. Pretend he only noticed afterward that she'd left, and had gone looking for her in concern.

It feels wrong to be disingenuous with her in such a way, though, even if she wouldn't be happy that he could sense things she might otherwise have kept hidden from him.

She's almost to the door before he sits up and calls out quietly, "Padmé." He says nothing else, but it's clear from his voice that he's awake and alert, and concerned. He will let her decide how she wants to proceed.
