The Doctor couldn't help frowning a bit as he listened to Romana talk about creating a gun. Really, it was what they had discussed, what they had come up with to do with the Dalek casing should they actually get one, but none the less he didn't like the fact that she could be so... fine with this. Another old companion turned soldier because of him. He already knew how she was in some ways, after the order she had given him to stop the Time War should it come to that. But it didn't mean he liked it.
"All you ever want when you come here is tea," he said, a slightly exasperated tone to his voice. He reached up to rub at his eyes for a moment before hearing the door swing open, then turned to look at the woman who'd shown up.
At least her double take made him grin a bit. "I'm guessing you're Star, right? You don't look like an Andrew to me. Hullo, I'm the Doctor, and this is the TARDIS. And yes, she's bigger on the inside."
