"Oh, yes, you said Shibuya but—" The Doctor cut off suddenly; Mr H had obviously understood and given him a more specific area anyway, so the explanation of what he'd meant was unnecessary. "I'll remember it: Cat Street, off Miyashita Park."

More surprising than finding that Mr H knew Donna—which... actually wasn't all that surprising, now that he thought about it; they were apart more than they were together around here, and had barely swapped stories—was that Mr H was familiar with dimensional travel, and familiar enough with time travel not to accept it without a second thought. The Doctor grinned brightly.

"Dimensional travel? Really? Well, that'll makes things easier if I meet you again before we've met," he said cheerily. "Always nice to meet someone who understands without needing an explanation."

Come to think of it, while he'd met some people—like Dean—who were completely skeptical about the idea of time travel (or dimensional travel), he'd met more than a few who were at least familiar with the concept. Maybe there was a connection there...

"And... yeah, she's like a partner," the Doctor agreed. She was a friend, a mate, a companion he could rely on... His smile turned fond, and he gave a brief chuckle. "'Lively' only begins to cover it. Donna is, well... She can be difficult, but she's brilliant."
