Right before Miorine, Guel and Prospera were about to leave for Earth, Suletta made her way to Hangar 78 and sortied in Aerial. After opening up about her feelings since losing the duel, Ericht raised her Permet Score to 8 and, subjecting Suletta to a data storm for the first time, revealed the truth about what they really were. After telling Suletta that she was no longer needed and that she could no longer latch onto her or on their mother, Ericht ejected her.
Prospera soon arrived and ordered Suletta to go return to the school and not follow her, leaving her with a thruster pack in space. Prospera took control of the Aerial and revealed her doubts about parting with Suletta, but Eri assured her it was their best option.
With Suletta left at Asticassia, Prospera sortied in the Aerial with Eri and arrived in Quinhabor on Miorine's mission to an earthian delegation. During the negotiations, Prospera and Eri initiated a permet field to cause the Earhtian and Spacian ground vehicles to open fire on each other. As the fighting escalated, the two flew off to an Ochs Earth storage facility and destroyed its cache of Gundam prototypes.
