Ace raised her eyebrow. "Is that why you cover yourself with them?"

The Doctor squinted at her. "This sweater was the first thing I grabbed when I was still in the first twelve hours of my regeneration. Since then, it's grown on me."

She looked at his umbrella. "And that?"

He pulled the umbrella closer to himself defensively. "What are you saying?"

She smiled. "Nothing… just that, most normal people don't go about wearing question marks or carrying one around with them.

The Doctor raised his eybrow. "Most normal people don't go about carrying a back pack full of dangerous explosives."

Ace's smile grew. "Guess were just not normal."

He smiled back at her. "Never thought so for a second."
