This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: The Trouble with Drax

This is the beginning to a story that concludes a character set up all the way back in Series 2 of the 4DAs (who technically comes from an obscure Audio Visuals story). It definitely lives up to my expectations. We finally get the backstory on how the Conglomerate came to be and it's timey-wimey and malicious. The Doctor is quite ruthless in this story, showing how far he can go when trying to protect his friends.
