Double-posting because I just remembered my favourite part of the episode, one which ironically showed more connective tissue with the series as a whole than any amount of rambling about Susan or an (admittedly very impressive) shiny Sutekh could manage:
The moment where The Doctor has had his tantrum, punching the elevator and sinking to the floor because the situation is getting out away from him and he’s also being forced to confront one of the earliest and most stinging abandonments he has ever committed. And Mel comes over, and you think for a minute she’s going to give a happy shiny pep talk like we might come to expect from this era. But instead, she puts steel in her voice, and is short and sharp when she tells him to “Fix it.”
Now, that’s a badass moment in general for Mel, but when you add it to this piece of context, it elevates the character and shows us that an actress who has spent decades with Mel Bush in her mind can drop so much nuance into single lines. Because remember, before 14 and 15, which Doctors did Mel spend the most time with?
6 and 7. Of course she has first of all absolutely no patience for The Doctor lamenting that his scheming and adventures have put his friends in danger. Her time (albeit mostly in the EU) with Seven showed her enough about him to know that this is an almost compulsive behaviour. Her time with Six, the most pompous, garrulous of all the Doctors, has well equipped her to know what The Doctor needs when they are at their most self-indulgent, and self-pitying. Not a kind hand, or a pep talk, but a swift kick up the backside and an emphatic challenge to do better. It’s amazing, that moment packs so much in. But then we have the entire Time Window sequence, which might be some of the most boring television I’ve seen recently. This is very meh episode for me, but there are moments, like so much of this season, where actors bring their A game and thus elevate what are some quite mediocre scripts on paper.
