Like the majority of the crew, it was curiosity that had brought the Doctor to the observation deck following the announcement. It was disgust and horror that had kept him there. He'd tried to fight and he'd tried to stop it, but his words had fallen on deaf ears and his actions had only led to him being held in place by one of the Kessak warriors until it was over.

It didn't matter that they'd tried to fight back. It didn't even matter than the punishment had been cut short in the end. The Daligig had forced their hand. They couldn't afford to wait and plan any longer. They had to act now.

As the observation deck began to empty and the injured - the many injured - were led away, the Doctor gave the space where the boys had been hanging a final dark look before turning away and striding towards the TARDIS.

He had work to do.
