Back on Earth, Keri's work looked a lot like most people's jobs looked. Notebooks on long tables, cups of coffee, colleagues talking over each other. But it wasn't everyone's job to meet with Earth's only known resident alien family. It was funny that Keri had never thought to ask Cabe before why he decided to pursue a job in astronautics. She had assumed he was like everyone else who just wanted to fly rocket ships and explore space. But knowing now that his brother was half alien, the reasons became clear. There was so much he wanted to learn about our universe and how it all worked.
They had two orders of business to start. First, they needed to make sense of the engineering notes that Lampyridae had left them. Second, they had to find a way to communicate with the Cassiopeians on a more reliable basis, which would also be the way they could communicate back home once they had embarked on the mission. Although their engineering specs could make it possible to travel faster than light, only those physical things that traveled with them in their ship would come along for the ride. To send messages that way would mean to harness the power of their warp drive each and every time, and that was just not practical.
"But let's think about this another way," Cabe suggested. "How did the Cassiopeians know that we needed help here? They didn't send a message on a warp drive, and they didn't use a wormhole. They spoke with the baby. They communicated with their minds."
"You’re not using my baby," Dallas said.
