Rose AU in which it’s Cally the Doctor meets rather than Rose Tyler. A bittersweet vignette, nicely characterised, especially Cally’s reactions to the TARDIS. (This author has written a whole series on this premise: Cally and the Doctor, please note some of it is adult-rated).
Post Gauda Prime, so spoilers for Blake’s 7. Servalan resurrects the Master, and neither of them get what they bargained for. Very clever.
The Doctor looks in the wrong place for a companion.
