Belinda and the Doctor were pitch perfect in this story, and so is the relationship between them! I really like the story as a whole, it works perfectly well, and feels like a very fitting story for this era, and has rejuvinated my love for the franchise and the current Doctor / Companion combination after a very bleak finale. I really love the characters and the plot, with some fantastic concepts like bio-engineered spaceships and a focus on mycelium! Having the bounty hunters AND the imperium felt a little crowded, with them both having the "STOP! We're back now to halt the plot for a while" moments a few times. Otherwise, it was a brilliant story and is very possibly the best Season 2 era episode yet. Especially as it actually DEVELOPS the Mrs. Flood mystery more than the TV show ever did before the reveal, as Belinda catches sight of Mrs. Flood and recognises her as her neighbour, something we NEVER see on the TV show. Highly recommend, Hannah Fergesen is a terrific author and I hope they come back for more!
