DOCTOR: A wise person once said to me, goodbyes only hurt because what came before was so special. Oh, and it's been so special. You, and Graham, and Ryan, and Dan. Nobody else got to be us. Nobody else got to live our days. Nobody. And my hearts are so full of love of all of you. Oh, I have loved being with you, Yaz. And I have loved being me. I think I need to do this next bit alone.

YASMIN: Let's not say goodbye.

DOCTOR: There's this moment where you're sure you're about to die and then you're born. It's terrifying. Right now I'm a stranger to myself. There's echoes of who I was and a sort of call towards who I am. And I have to hold my nerve and trust all these new instincts. Shape myself towards them. I'll be fine. In the end. Hopefully. Well, I have to be, because you guys need help and if there's one thing I'm certain of, when people need help, I never refuse. Right? This is going to be fun.
