LIV: I’ll stay, you know. As long as you need me

DOCTOR: We all need someone. That’s what hope is. Other people.

LILY: Doctor... Pity… me!

DOCTOR: Fear me.

LILY: What?

DOCTOR: Tell this to your gods. When they punish you. When they stretch you on the neutron rack. I’m still here.

LILY: But you? You’re one little man!

DOCTOR: I am not a man! Not a human being! I am a complex space-time event! I am Lord President of Gallifrey. The Traveller from Beyond Time. I am the Sandman. The Oncoming Storm. I am the Ka Faraq Gatri. Destroyer of Worlds. And sometimes… Only sometimes… I am your worst nightmare. I am the Doctor. And I take care of my friends.
