It's a case of cracking premise, lacklustre execution in this excursion to the planet Messaline. The Doctor is joined by both Donna and Martha as he is confronted with a serious case of "dad shock" after encountering a young blonde lady called Jenny. We'll spare you a full on rant about the disappointing quality of the episode (check out the full review on Digital Spy immediately after the episode has aired) and instead serve up a few spoilers (and two red herrings)...
The Doctor is "processed".
Donna refers to The Doctor's daughter Jenny as "GI Jane".
Martha falls into a bog.
The Doctor puts a gun to a man's head.
There is talk of a being called 'The Great One'.
The Hath are genetic descendants of a race known as the Haemovores.
Martha puts a fish's shoulder back in place (or perhaps in plaice?).
The Doctor doesn't need a female to spawn a daughter - he is capable of doing it all on his own.
Jenny tells The Doctor that she saw someone called Susan die in the Time War, which upsets him greatly.
After putting a stethoscope to Jenny's chest, The Doctor is surprised by what he hears.
