Days Gone By

AU, second season where 10 travels with Rose and Jack Harkness. In an attempt to save his life, Rose sacrifices herself to save Jack in a war between evil scientists, de-aging the pair of them. The Doctor now has to take care of two children, save the world, and not get killed all at the same time. RoseX10 Rated T for possible use of Harkness-style innuendo. I do not own Doctor Who
