The life breathed into her finally clicked and Natasha returned to consciousness. She felt the impression of someone doing chest compressions, felt the lips on hers and the breath shared with hers. And she heard Bruce's voice from somewhere. Stay with me, Nat. And then she was finally able to put it all together. She opened her eyes, took a deep breath, and started coughing.
"Bruce?" She said, when she was finally able to stop coughing and catch her breath. She was alive, but her lungs ached and she felt weak.
She wasn't so out of it that she missed his state of undress though. She even smiled a little.
"This is a good look on you."
She found it a lot easier to joke and deflect in situations where she'd cheated death. But she knew full well what must have happened for him to save her. She reached out to touch his arm. Somehow, he'd managed to change into the Hulk and change back again. She'd want to figure out how later, but for now... for now, it was enough that they were both alive and that the ship wasn't in pieces.
