"...Wow. That's really...my people haven't had functional relativistic laboratories in over six million years -- they were all destroyed in the war," First Aid explains, with a hint of shame in his voice. "That's pretty amazing."

First Aid tilts his head slightly to one side, studying César's reaction. "Do you regret it?" he asks gently.
