Teo spends a lot of time with Aria, the EROMI plant assigned to his social group. When Aria leaves to fulfill Dr. Admatha's mission, Teo has a difficult time understanding the difference between her mission and the orders stems usually receive, which mean they won't be coming back.
He doesn't have long to fret over her absence though. When his human counterpart is convicted of a capital crime, Teo's purpose is questioned by EROMI's powers that be. Who will Aria find in Teo's place when she returns to Endfield?
