When Padmé started crying Anakin felt infinitely worse, automatically jumping to the conclusion that it was somehow his fault.
“I can just-” he started to say when Padmé scoot towards him on the bed and wrapped her arms around him. He was going to offer to leave; he was upsetting her, the opposite of everything he tried to do. But if she didn’t want him to leave, that desire being expression so strongly (and yet in an utterly confusing way for Anakin, for she felt quite distressed in the Force) he finished with instead, “Oh.”
He wouldn’t deny Padmé anything, of course, and he pulled her close to him.
“I didn’t mean for this to happen. If you want me to leave and give you space, I will,” he said, trying to find a solution that would work.
