The Kara thing was one of the most hilariously forced bits of BS I've seen in quite a while. You've got a guy who has been in captivity for 20 years and is skiddish about everything, and a woman who has just learned that her father figure really did die, her mother figure is a robot, and her world is in turmoil. So of course because they knew each other when they were toddlers, they have an immediate romantic interest while the world continues to turn to shit around them.
