I actually thought of the Biblical version - Lot and his wife when I was listening yesterday.

I also would like to see Jack die at the end of MD. And then I think TPTB should make a new series with Jack during his years with the Time Agents. Much like the Doctor he could visit people from his past and the future including all our friends from TW S1 & 2 along with new adventures.

Bonus points if they brought back James Marsters as well. Hey, I can dream, can't I?
