"Never happen," he murmured into her ear, one arm slipping around her to hold her in a loose embrace. "I'll always want you here. Always have."
Now that he was tucked into bed again, with Rose's warmth at his side, he was finding it more difficult to keep his eyes open. He needed every scrap of sleep he could get, and his body had had just about enough of his forcing himself to remain conscious and mostly coherent. "I missed you," he said, because it bore repeating. "I'm not letting you go again, Rose Tyler."
Moments later, he was asleep, his expression smoothing out and becoming peaceful as he finally got some much needed rest.
