The Trickster and Andrea in “Unfinished Business”

Andrea Yates. They want to kill you all over again. Remember your bargain with me.

You tricked me! You used a child, and now you're destroying the Earth!

Chaos is good.

Well, I say no. If there's one thing I can do with my life, I can put a stop to you for good. I've changed my mind. I'm taking the deal back!

Then you will die!

I've been dead for forty years. Been a good life. It's my birthday. Bye, Sarah Jane. I'm going now… AND YOU'RE FREE! [throws the puzzle box at the mirror]
