Doctor Who thread II: "I should have a hat like that." [SPOILERS]

[Androgeus]

Series 1 had one episode about children, but it was a two parter and was creepy as anything. Series 2-4 had around 2-4 episodes about children.

5 had like three. 6 has had almost every episode but the first one have a children subplot.

Curse of Black spot could have done without the kid I agree. The time could have been given to the pirate who suffer plot existence failure.
The father sub-plot in Rebel Flesh/The Almost People did explore one of the problem with clones.

Other episode that have kid sub-plots

Night Terrors is Fear Her done better, so the kid is kinda central to the plot.
Closing time is just filled with awesome (well apart from how they solved the problem).

I don't think there's really anything left to say about the main plot arc. (If you need to know which side, lets just say I'm easily pleased)
