So, while rereading the final scene of First Dates and Firefights and thinking about possible recruits for Akio with ties to the early 20th century, I came back to check this list. And sure enough, Jenny and Vastra are listed as being in cryo. (Early 20th Century, close enough to Victorian London to count) The image of Touga trying to recruit those two is wonderful, and now I'm kinda sorry that the Castellan shot that idea down.
