Thunderstone

Myah and her brothers hold Becky and her parents hostage. But when Noah is about to give himself up, another Noah enters the grotto. Becky has brought the Noahgram! Myah releases them, believing its the real Noah. Back at the compound, Noah states his plan to destroy the comet. Liz reminds him that if he does alter the future there will be no Haven. A vote is taken and it is decided that Noah should stop the comet for the greater good. Myah having seen through the Noahgram, arrives at the Compound to see Noah and Arushka white-out. They arrive in the year 2002 at Cortillo Plain. This is the command site for the rocket attack on the Comet which is already on course for Earth. They confront General Cardell, the commanding officer and ask him to abandon the plan to use nuclear weapons to destroy the comet. Cardell dismisses them as cranks. In Haven, Geneva accidentally gives away part of Noah's plan to Tod. Noah tries to warn the world of the imminent mistake on television, but Cardell stops the broadcast. Pursued by security vehicles and helicopters, Noah and Arushka race in to an empty hanger where they white out, leaving the General Cardell absolutely confounded. Back in Haven, its decided the Nomads must take the Beast back to Cortillo Plain and preempt the rocket strike themselves. Liz won't go since she used to work at Cortillo and would meet herself. Noah's father Simon and Becky elect to stay behind with her, but she and Noah quietly confer: there may be a way they can all be reunited. The Nomads and Noah pile into the Beast along with Moshi and Dolly. The Beast appears on Cortillo Plain but Myah and the brothers are clinging on to the trailer. They've made the journey as well!
