C is for... Cane Family

Passengers on the Crusader 50 shuttle tour of the planet Midnight, encountered by the Tenth Doctor. They were husband and wife Biff and Val, and their son Jethro. The planet's surface was bathed in X-tonic radiation, and no life could survive there. At first everyone got on well - after the Doctor had sabotaged the annoying in-flight entertainments system. Biff and Val told the Doctor of a visit to what they thought was a swimming pool but turned out to be merely a concept. Jethro was a somewhat moody teenager, who dressed in emo fashion, and who acted as though he did not want to be on this holiday.
Once the vehicle had broken down, and seemed to be coming under attack from something outside, tensions mounted. The unseen entity appeared to have got inside and taken over a fellow passenger - Sky Sylvestry. Biff and Val became unnerved when she started to repeat what everyone was saying. Fear and paranoia increased as Sky then spoke at exactly the same time as the others, and then began to preempt them. Jethro attempted to keep calm and act reasonably, but Val became more hysterical, triggering Biff's aggression. This affected everyone else, and the Doctor had to stop them acting like a lynch-mob as they planned to throw Sky out of the craft. The entity then moved into the Doctor himself. He would have been thrown outside if it hadn't been for the Hostess realising what had happened, and sacrificing herself to drag Sky and the entity out of the craft.
Val feebly attempted to defend their actions, and Jethro was clearly upset to see how his parents had behaved.
