At this point Chibnall is simply burning Doctor Who to the ground out of spite. Nothing in this sorry mess is even remotely good. Yaz, Dan and the Professor are on a quest with no explanation of how or why. Vinder now just turns up in a place solely to make it look like Chibnall had a plan. The whole of UNIT history is trampled on because because and the stupid Timeless Child nonsense rears its ugly head again and scenes change because hey, random scene changes are exciting, right? It's throwaway rubbish in a throwaway universe in a throwaway era written by a writer who should have been thrown away years ago. Terrible. Just terrible.
