"Dalek" is one of the all-time greats. Really ramps up the threat and proves that a lone Dalek is capable of mass destruction and extermination. No need for armies.

And it makes sense. The Dalek absorbed her DNA in "Dalek" so she connects with it. In the finale, though, she knows the Daleks are straight-out evil.
