This was a fun! It was very light and easy, but that’s no reason to discredit it. That ending is really weird though, huh? It very clearly sets up a third novel which never released, but for about a page, after questioning himself for most of the book, Graham admits something might be seriously wrong with him. The Doctor puts up her guard and examines him, and Ryan is almost ready to throw hands with the Doctor if she steps out of line and hurts his granddad. Graham is after all nothing if not sympathetic, and not one of her companions ever truly believes she’s fully trustworthy, and neither do we. For about a page we see a completely new dynamic within the group, and it’s pages like that which are the reason why I’m going through 13’s expanded media. Because every so often, something like that happens. And if you’re not paying attention you miss it.
