Summary: Setsuna investigates just how much a Gundam can change its Meister, with Tieria serving as the perfect example. Set during episode 8 of season 2.
In some distant corner of his mind, Setsuna was aware that Sumeragi had prepared Tieria for this mission. Certainly the giggling that followed him as Mileina waved goodbye to him as he entered Seravee was unusual. But little else seemed different, as Tieria entered his Gundam and prepared to launch for Earth, with Setsuna following him in 00 Gundam.
When they landed in a clearing specially prepared for their arrival and emerged from their Gundams, however, Setsuna saw the change. He almost missed it at first; he was busy examining the limousine that had been prepared for them and puzzling over the strange clothing laid out on the seats. A chauffeur's outfit? Clearly, that was his; but what purpose was the evening gown meant to serve? He got his answer when he turned to see Tieria emerging from Seravee.
When Tieria had entered his Gundam, he had had short hair, and his flight suit had fit perfectly. Setsuna understood this: short hair was practical, and Tieria would never stand for ill-fitting clothing. But now it was different. His hair flowed down his back, and his flight suit--
The pants still fit, as if there had been no need for a change there. But the jacket was unzipped (as Lockon Stratos had once often worn his, but with something distinctly different in this case) and yet still strained, and the undershirt beneath it was tearing at the collar. Clearly Tieria had taken Sumeragi as a model. But how had it happened?
Gundam. Somehow, Gundam had granted Tieria the disguise he needed for this mission, far more efficiently than any costumer could have. Setsuna felt something stir inside him at the thought.
"There's no need to stare," Tieria said, regarding Setsuna with some bemusement.
"Agreed," Setsuna said. "You should change outfits. Your undergarments are beginning to rip."
"Of course," Tieria said. But where he had shown no shame at all before, as he started to take down his flight suit and pull off the undershirt, he flushed a little. "...Let's take our positions in this vehicle, Setsuna."
Setsuna nodded and slipped into the driver's seat, with Tieria following into the room behind. Setsuna attempted to stare forward for as long as he could, but the thought of Gundam changing Tieria, the curiosity about what it had changed him to, overwhelmed him. Finally, he turned around.
Tieria was almost done slipping into the dress at this point, but the top was still undone, and the tops of his breasts were bare and visible. As Setsuna had suspected, they were quite real. That was no surprise. Gundam would not make false changes, after all.
"Tieria Erde," Setsuna said. "What happened to you, in your Gundam?"
Tieria looked up from fussing with the catch on his dress with a start. It fell down around his shoulders, and his breasts slipped free entirely. Even the nipples looked real, although this was the first time Setsuna could recall seeing them--in female form; "on a woman" wouldn't be quite right. There were some things he had not thought it proper to watch Marina Ismail doing, after all. Somehow it seemed less improper with Tieria.
"Setsuna--" Tieria started, but he cut himself off, struggling to control his sudden fierce blush. "There's no need for you to see this."
"I am curious," Setsuna said. He leaned over the top of the seat and, on an impulse he could not quite identify, reached out to take hold of Tieria's breasts. They were soft and warm in his hands, save for where his nipples suddenly hardened against Setsuna's palms. "What has Gundam done to you?"
Tieria took a deep breath, and Setsuna felt him move. "You are straying from the mission, Setsuna F. Seiei."
"No," Setsuna said. "We were provided with extra time for such a purpose."
"I don't believe it was for--" Tieria began. Then Setsuna squeezed, and Tieria squeaked.
"Tell me," Setsuna said.
"It isn't only Gundam," Tieria said. "My own body is designed for such changes as well. But the GN particles are a necessary catalyst." He hesitated. "And I am not certain of how far the change goes."
"We will find out," Setsuna said.
