A really fantastic dramatic instalment concerning the hunt for the missing Arborecc onboard the Space Security Station. The twist that Major McLinn has been turning people onboard the space station into Daleks really pushes the characters emotionally, especially with one of the Daleks being Mark Seven's friend Felicity. It does have shades of Parting Of The Ways, but the idea of Dalek conversions always works well from a dramatic perspective.
A scene that really stands out is when the Arborecc Dalek begs to be 'exterminated'. It's heartbreaking and reflects how harsh the major's actions are. He is weaponising people onboard his space station without their permission, and turning them into the thing they hate.
