- [the Doctor is trying and failing to sonic the mirror]
- The Doctor: Oh, and I can't force it with the sonic like before because it's clever and it's adapting.
- Yasmin Khan: What if you do something it hasn't dealt with before, like reverse the polarity or something?
- The Doctor: Yasmin Khan, you speak my language!
- The Doctor: I've told you about the Solitract, right?
- Yasmin Khan: Literally never heard the word before.
- The Doctor: Solitract. Sol-i-tract. It's a theory a myth, a... a bedtime story my gran used to tell me
- Yasmin Khan: You had a grandmother?
- The Doctor: I had seven, but granny five, my favourite, used to tell me about the Solitract.
- The Doctor: You want the whole universe. Someone who has seen it all, and that's me. I've lived longer, seen more, loved more, and lost more. I can share it all with you, anything you want to know about what you never had. 'Cause he's an idiot with a daughter who needs him. So let him go, and I will give you everything.
