1x03 The Unquiet Dead

Before 당신 ask, yes, I already know who Missy is. This is just two theories I have that involve her.

Theory 1: Gus and the Orient Express

I strongly believe that Missy was behind Gus and the events of the entire episode, "Mummy on the Orient Express".

Here's why:

1. Gus was an AI, as was Seb, Missy's receptionist that she most likely created.

2. Gus wanted to study the Foretold and reverse engineer the technology keeping it "alive". And this technology could very well be similar to what Missy used on her Cybermen army made out of corpses, much like the Foretold!

3. Missy has the TARDIS' phone number...

Father's Day
This episode had it all. It managed to get exactly the right balance between emotion, fear, characterisation, relationships, and the concept of time. The Doctor and Rose's friendship was tested, but they came out of it stronger than ever. The scenes between Rose and her dad were heart-wrenching, and so was the moment when Jackie realised that Rose was 'her' Rose. The end scene where Pete dies in his daughter's arms is utterly tearful.
Ranking: 10/10

The Empty Child/The Doctor Dances
This two-parter was easily better than the Slitheen...
