In this episode, we take a detour to follow Ruby and get more development for UNIT. It's overall a solid story, but you can't help but feel like what's going on with the Doctor and Belinda is more important. It takes overcoming that initial hesitancy to real get going, mainly when Ruby's adorable klutz boyfriend Conrad turns out to be a far-right provocateur in disguise. Things pick up more from there as the tensions ratchets up with UNIT under fire, and then we get what is probably Jemma Redgrave's finest performance as Kate. She steals some of the spotlight from Ruby as she lets an alien monster (can we not do better than Shreek?) loose. The best part comes from one of Ncuti Gatwa's finest performances as he dresses down Conrad.

Overall, it's fine. I do like Ruby a lot as a character, but we honestly don't get too much farther than 'life after the Doctor can be difficult'. It was good to see the UNIT gang again, but in only eight episode I wish we could've kept some of this material for the spin-off. At least we know who told the Doctor Belinda's name!
