I'm still mentally recovering from this episode. It was just amazing from start to finish. The culmination of everything we've seen before and setting up for boxset 7 and beyond, it was brilliant. I was thinking throughout about "the invaders" and wondering who they could be. With Dan Starkey voicing them, I had a hunch it may have been the Sontarans but wondered if that was just my Dan Starkey bias as I'm so used to seeing and hearing him as the potato shaped monsters. However, I was very pleased to learn I was right, with the big twist at the end being that the Sontarans have now taken over Gallifrey! What a brilliant twist and setup for the next story. Also brilliant was having the Sinsa confirm what I suspected from Nowhere, Never onwards, that being that Hieronyma Friend is somehow using the different faces of the Eighth Doctor's companions. We did get a hint to this back in 2023 when in the Audacity reveal news article, they mentioned how Jaye Griffiths was in Time War 5 and I always thought that was odd as companions have often been in prior episodes of the show, especially since Jaye Griffiths was in the TV series as well. Of course now we know that she was using Audacity's face, but we wouldn't have ever suspected that back during Time War 5. Now, she's used Helen and C'rizz's faces too and I can't wait to see who they'll have playing her next! And all of this without even mentioning the main twist of the episode. Alex turning on the Doctor was an absolutely brilliant scene and I cannot wait to see where it goes from here! It's going to be an amazing story going forward and I'm looking forward to seeing how that all pays off!
