It was definitely after the whole 'we would like that world' bit and after the question of contamination via the shuttle had been raised though. I was happy with that bit: aliens want to steal planet via shuttle, mobilise resources to secure it : for me that was OK without elaborating.

The suicide was the bit where I was grasping for more plot: she doesn't like him rewriting the future even to save her skin (bit of a turnaround there, but OK) but surely, he has already done that, suicide at home not same as heroic death in unknown circumstances? Although I can see that the suicide was needed to develop the Doctor's character arc, it didn't quite work for me in terms of Adelaide's, I would have liked that developed more.

Hey ho. Good telly though, not complaining.
