Companions: Donna Noble (Catherine Tate), Martha Jones (Freema Agyeman)
Summary: The Doctor, Donna, and Martha are taken by the TARDIS to a planet where humans are fighting an endless war with fish-like aliens called the Hath. Each of the human soldiers are actually cloned, and one is made of the Doctor. This results in Jenny. At first, the Doctor is appalled at this, but realizes that he must accept this new creation and stop this war.
Review: This is an episode where the Doctor encounters a perversion–a copy of himself who kills without question. The Doctor must confront that part of himself that he detests–the dark nature within us all. I liked how Donna gave the Doctor the slap in the face he needed in order to accept Jenny.
The Hath were really the episode’s only low point. They seemed kind of ridiculous in their design. I’ve heard some people complain about the Doctor’s “I never would” speech because there are times the Doctor has indeed killed people. But here’s the thing: the soldiers were killing people because they were ordered to. Yes, the Doctor has killed, but he only does so if he sees no alternative. So I don’t think this episode has the Doctor acting out of character as some have claimed.
All in all, this is one of the best episodes of Tennant’s era.
Overall Review: 9/10
Continuity: The Hath are from one of the planets that were “moved” in “The Stolen Earth”. The Doctor mentions that he was a father once, as well as a grandfather.
Trivia: Jenny is played by Georgia Moffet, the daughter of Fifth Doctor, Peter Davison. She became David Tennant’s wife.
