Padmé is already dead by the time Anakin gets back to the ship, Obi-Wan’s death still fresh on his hands.

He stays there for a long time, in complete disbelief- she still looks so alive, her skin is still warm, her neck only slightly swollen- the bruises hadn’t even begun to form yet, but no matter how much Force energy Anakin pours into her, Padmé is dead, and so is their baby- babies, the Force whispers to him.

Sidious had not foreseen what would happen when Vader returns to Coruscant alone; after the Emperor is dead, the last thing Anakin does is put his lightsaber through his own heart, thinking to himself that he is about to restore balance, once and for all.
