The Doctor, Rose and others in “World War Three”

There's a way out.

What?

There's always been a way out.

Then why don't we use it?

[to Jackie, over the phone] Because I can't guarantee your daughter will be safe.

Don't you dare! Whatever it is, don't you dare!

That's the thing. If I don't dare, everyone dies.

Do it.

You don't even know what it is. You'd just let me?

Yeah.

Please, Doctor, please, she's my daughter, she's just a kid.

Do you think I don't know that? 'Cause this is my life, Jackie - it's not fun, it's not smart, it's just standing up and making a decision. Because nobody else will.

Then what are you waiting for?

I could save the world but lose you.
