It's the weirdest thing Jo's said all day.

Pain on her arms, her legs, her exposed back. The edge of the cliff gets closer, the water gets louder. It won't be the first fall she's taken since Milliways. It won't even be the first cliff she's willingly jumped from.

Rachel's scream as she launches herself as far from the edge as possible isn't fear. It's anger, as the zaps continue.

And as the wind hits her face and her body plummets, it's equal parts exhilaration.
