Vae's Nine
Jack had found a 1940s-style dance hall (there wasn't much you couldn't find in New New York, especially this somewhat psychically-sensitive one). He'd had a grand evening dancing and flirting with the more or less real patrons of the dance hall, and was wandering out of the hall with a girl under each arm, both laughing at the outrageous story he'd just told them, when he caught sight of the Doctor across the street. Not his - definitely not his, unless the Master had somehow managed to make him regress a regeneration - but the first he'd seen here with that face. And a face that just fitted his evening.
"Hey, Doc!" he called, sending the girls back inside with a wink and a pat on the rump and crossing the street instead. "It's goood to see you!"
