Disquisitiones Arithmeticae

'Woman' is, I think, the weakest episode to date. It was good that they explored the consequences of immortality--but you'd think that someone who'd been around for eight centuries and had grown hard from repeated sorrow would be too naïve to fall for that lion guy's story. I did like the idea that she's gonna watch out for his "leftovers", which explains handily why he felt that he'd seen her before when they first met.

Twelve's speech in 'Inversion'...wow. First time Capaldi's come close to making me cry, which is quite a compliment to him.
