AN: This is a plot hole filler POV of Creta's superiors of their military after Edward's capture. See people I don't leave you hanging I just like to ease into the story.
Unbreakable Chap.10
The Cretan superior's knew they had their weapon ever since the day they laid eyes on the golden haired alchemist from Amestris. He was strong minded, his fighting skills were unmatchable, and his improvisation in a fighting situation was perfect, he could adapt his fighting with more attackers. They had thrown him into situations to monitor him as they tortured him. Even though he couldn't do alchemy anymore he could still do mass damage with his fighting.
They day he started poking around four years ago they hadn't paid very much attention to him, but upon finding out he was Edward Elric the famous Fullmetal alchemist, the one who fought against the father of the homunculi on the Promised Day five years ago they knew they had to try to break him.
After capturing him and trying to get information from him and him not telling them anything they tried a new strategy. This was a strategy of testing his mental state and his ability to handle multiple attackers. His mind had all but impressed them as he fought five attackers and took down three before even breaking a sweat. They knew they had something special in this alchemist.
After contacting Mustang and confirming who he was they went to work on Edward. Programming him for their destructive plan was of the utmost importance. Making him feel like an actual prisoner and challenging him every couple of weeks with beatings and of course other tasks that he never knew about.
The Cretans had come up with a plan; they didn't want peace with Amestris because their dealings with them in the past hadn't turned out in Creta's favor. So now with this remarkable opportunity in front of them, right here in their own prison their new plan unfolded.
What if they could start a war between Amestris and Xing? The two counties would be so busy fighting each other that they could sneak in the back door and wipe out Amestris one town at a time and no one would catch on till it was too late.
Edward was the perfect person for the job, what better way to start a war then have an ex-military soldier and alchemist kill the newly crowned Emperor of Xing, his Royal Highness Ling Yao.
They went to work on Edward torturing him and brainwashing him to the point of breaking down his mind and building it back up again. Mustang's inquires only strengthened their idea that Edward was perfect for the job.
Having someone dress up like Ling and making him focus all his hatred onto him only strengthened the idea the plan would work. Giving him one word that would set him off when said was the perfect way to get Edward close enough to kill Ling.
They thought their prayers had been answered when one of their spy's came back and informed them that Edward's younger brother was marrying the Xingese princess Mei Chang and the wedding was taking place at Ling Yao's personal palace.
Years before they had placed an idea in Edward's mind, to escape. They put him and another prisoner in a cell where they knew they ground would handle a tunnel then they planted that idea in Edward's head. Edward and the other prisoner had dug their tunnel but they were doing it too slow, so while they weren't in their cell some of the Cretan soldiers dug it out for them. Neither Edward nor the other prisoner were the wiser.
So this whole thing was a set up all the way down to threatening to execute him. They needed him to make a move to escape and now by keeping tabs on him as his brother's wedding got closer they knew he was in position to carry out their dastardly plan. They just hoped that one person would say the programming word and they made that word something that would only be said at a wedding which was 'Cake.'
While they trained him with that word they had to figure out another word that would bring him back and break that outburst so they used the love he had for one woman to calm him, his deprogramming word became 'Winry.'
When Mustang had quit inquiring about him they knew it was time to strike. They were just going to inform the Amestrian military they had executed him and let him out, but letting him escape was more believable and no one would be the wiser.
