DOCTOR: I mean, basically the code came from nowhere, but then so did the universe, and no-one complains about that.

DOCTOR: You are being mansplained by a briefcase.

JOY: I thought I was being mansplained by you.

DOCTOR: Honey, the Doctor's in the room - it's the mansplain central.

DOCTOR: Do you know how lonely you are? You live in a great, big, giant spaceship and there aren't any chairs! And you haven't even noticed because nobody ever comes round!

DOCTOR: Ugh! Do you see? This is why nobody likes you! You have to be mysterious all the time. That's why everyone leaves you. That is why you are always alone.

JOY: She died on Christmas Day. On Christmas Day! I said goodbye on an iPad! Because of the rules! She died alone! And those awful people and their wine fridges, and their dancing, and their parties, and I listened to them, and I let my mother die alone! So I can never be home on Christmas Day, and I can never be with anyone on Christmas Day because I let her down. I let her down on the last day of her life, on Christmas Day. I can’t ever change that. I can’t ever change it.
