Reinette and The Doctor in “The Girl in the Fireplace”

Oh, such a lonely childhood.

It'll pass. Stay with me

Oh, Doctor. So lonely, so very very alone.

What do you mean, alone? You've never been alone in your life. [pause] When did you start calling me Doctor?

Such a lonely little boy. Lonely then and lonelier now. How can you bear it?

[stunned] How did you do that?

A door, once opened, can be stepped through in either direction. Oh, Doctor. My lonely Doctor. Dance with me.
