The Doctor was looking at her, he smiled when she said the ship was bigger on the inside. "Is it?" He was grinning a bit. Of course he knew it was and he loved hearing those words. It had been awhile since anybody had been travelling with him to even say that. 
He had missed those words. He knew that the TARDIS though was amazing to others who set foot into it. 

The Doctor looked around as they stepped out. "Ah yeah this is earth. We are in the town Cardiff, The TARDIS needs to refuel and the rift is in Cardiff so I often land here for that, Though have a friend that lives here too, But I thought we could get something to eat, and since you might not have been here, I could show you around."His stomach seemed to growl as soon as he mentioned food. He wondered if she had eaten anything yet. He smiled a bit.

"Ah yeah does smell good," The Doctor was smiling. He looked at her "Is bright, I can get you some sun glasses from the TARDIS if its too bright," He knew that she might not be used to it. "Though you might adjust to it given time."
He was happy to show her around really. The Doctor looked around wondering where they could go to get some food. Chips might be nice.
