Also, when Tina, Sarah and Jarrod kidnap Heather from the house in Scotland so they can take her out on a little adventure to a random dimension, they thought they were going to end up someplace exotic or run into yet another strange species that they'd get to document and study. Unfortunately, the random dimension they chose didn't provide them with any of that. Instead, they find themselves in some very familiar surroundings, and run into some people they're more than intimately acquainted with.
And finally, when Commander Arthwal's investigation into the mystery surrounding the deaths of Alarwyn's parents leads to a revelation that could rock the very foundations of the Nathalis political system, he has to choose between following the status quo and doing what's right in order to give Alarwyn the justice she deserves.
