She kissed him back, not really noticing any change at first. It was a slow process, starting at her hands and feet where there wasn't much difference. She was about to ask him when it would start when it hit her chest.
Growing a new heart wasn't exactly an easy process. She coughed, trying to catch her breath without much success. Her knees buckled beneath her as her fingers grasped for the Doctor's arms.
Her mind.. It wasn't as overwhelming as the time vortex had been, but everything was expanding. It was almost as though you could fit an entire galaxy in there, and it made her feel so far away from everything. Like she and the Doctor were an entire universe away..
But it was only one heartsbreaking moment. Then as quickly as it had expanded, it contracted again and she was thrust back into the Doctor's arms, closer than ever. Her legs had long since gone weak and she would've fallen if he hadn't been there to catch her. He would always be there to catch her.
Rose looked up at him, her breath still heavy and a thin sheen of sweat on her brow. There was a playful twinkle in her eyes.
