Just a short I thought I'd give a shot at. Dunno how it turned out, so lemme know.

Treyanessa, Zahara Suri, Rayhenna, Azuka, Merlyn, and Casmir are all visiting Pompeii when their TARDIS breaks down- just before Vesuvius explodes! Tessa finds the Doctor (by accident) and runs away. Will she face him? Will they save Pompeii? Will they all travel together? And the most important question of all- will Tessa and the Doctor hook up again?
