A Good Man Goes to War

TV Series 6, episode 7
Aired: 4 June 2011
You don't normally get quite so much detail about a companion's lifespan, but River breaks the rules as usual. We saw Amy going into labor in "The Almost People," but this is the first time Baby Melody appears as a character. Unfortunately, she's also replaced by a ganger, and spends the next several years in Kovarian's clutches.
