"Oh Rose, this is brilliant! Can you believe it?" The doctor's expression lit up like the sudden switch on of a light bulb in the dark. His old eyes had life once more; like they had those many times before. Always with her, never anyone else. Just Rose.
"It's remarkable. Can I please go get my jacket now? It's bloody freezing," her shivers not being hidden from him in the slightest.
"Oh calm down," he smiled at her, "take mine. I don't really get cold anyway." The man helped her snuggle into his suit jacket and then looked back at the planet before him.
The faces of both travelers showed excitement, just like it should be. The growing presence of the unknown still lingering in their brains.
That's what they both loved about it.
