The Doctor and Clara in “Hell Bent”

[losing memory of Clara] Run like hell, because you always need to. Laugh at everything, because it's always funny.

No. Stop it. You're saying goodbye. Don't say goodbye!

Never be cruel and never be cowardly. And if you ever are, always make amends.

Stop it! Stop! Stop it!

Never eat pears. They're too squishy and they always make your chin wet. That one's quite important. Write it down.

I didn't mean to do this. I'm sorry.

It's OK. It's OK. I went too far. I broke all my own rules. I became the Hybrid. This is right. I accept it.

I can't. There has to be something I can do.

Smile for me. Go on. Clara Oswald… one last time.

How could I smile?

It's OK. Don't you worry. I'll remember it.
