This was a strong conclusion to the boxset and managed to being a lot of the themes of it together in satisfying fashion. Things start dark with Charley apparently contemplating suicide, but luckily it doesn't reach that point. Robert is back along with his awful father and horrible fiancé Millicent who would rather be marrying his father too. At the same time, the Viyran obsession has reached the logical conclusion that all life is a virus to be expunged. What really makes this story sing is India Fisher's performance: Charley is at once still a little girlish (with the water bottle mascot), and also very confident in herself when she's flirting with Robert. This whole story felt like Charley was maturing to where she can be the star and not the companion anymore, and it was well-managed character growth. Interested to see what happens in set two, I assume the Viyrans aren't finished because I am eager to know just who their creator is...
