I like ruby in this episode more than in a lot of season 1. I like how they show that Ruby is paranoid after travelling with the doctor. I like the reveal that Conrad is part of Think Tank (the organization in Robot) and is a horrible guy. I think the shreek is cool. Kate Stewart was good in this episode and I thought UNIT was the most interesting it's been for a while. I like seeing the doctor at the end and it explains how the doctor knows to look for Belinda.

Overall, I enjoyed this episode a lot and its another great episode to this season.
