Return Home (Domecoming)
Light Beam (Shining Sign)
"Riru 124C41+" (リル124C41+/RE-L1244C41+)
Re-L recovers from her illness. Daedalus shows her the disturbing mechanisms responsible for the dome's continued survival. Vincent makes his way home, slowly losing his companions along the way, ending up alone with Pino. A group of infected AutoReivs is unleashed on Re-L, Iggy, and Daedalus. The episode ends with Daedalus filling out Re-L's death certificate.
- The title of this episode comes from the novel Ralph 124C 41+ by Hugo Gernsback, one of the most influential science fiction stories of all time. The title itself is a play on words, meaning "one to foresee for one another", which is a core element of Re-l's character throughout the series—perhaps her raison d'être.
