Fridge / When Worlds Collide

• Fridge Brilliance: Dr. Hendron arranges for both Eddie and Julie to go even though she wasn't picked in the lottery. On the rocket, there are only two empty seats, which were for Hendron and Stanton. However, Tony mentions that a boy was stabbed right after the list was posted. If he had been picked and became too injured to make the journey, Hendron likely gave his seat to Julie.
• Fridge Horror: 40-odd people is too small a number to ensure long-term survival; there is insufficient genetic diversity. The same with the animals taken on the ship. Factor in deaths due to accidents or illness, and there will be nobody left in just a few decades; a hundred years, tops. The novels avert this by having three ships successfully make the crossing, with a total number of survivors in the hundreds.
