Reactions
Winry and Pinako

I randomly thought ' what would Armstrong do if he found out about Roy and Ed?' and then I kinda typed up this.

After the scar incident Ed took a trip to Risembool. Since his arm was broken he had to have a body guard. The guard was none other then his his boyfriend. Roy mustang. They had Al with them in the train cart as he didn't trust Ed and the Colonel alone.
"Seriously Al? You're not bothered by this?" Ed asked while sitting next to Roy and his arm lying protectively over his shoulder.
"As long as you're happy, I'm fine with it" Al answered from his little box. Then after Ed remembered who they were going to see Ed's head dropped.
"Do you think they'll hate me?" Ed asked miserably, fearing their reaction. Al knew who 'they' were. 'They' were Windy and Pinaco. Roy decided to keep quiet as this was something Al need to tell Ed not him.
"Brother, if Winry and granny can accept you joining the military and putting your life at risk every day, they can accept you for being gay." Al reassured him.
"Thanks" he said as he snuggled closer to Roy's chest. So couldn't help but feel happy for his brother. He found someone who made him truly happy. A happiness he or anyone else couldn't give him. He found true love.

They got off the train and started their walk to the Rockbell's house. Winry sat on the porch when she saw 3 figures walking down the path. More accurately 2 figures and the taller one was carrying a big wooden crate. She recognised Ed and Al, but not the 3rd one. As they were near she could see their features, plain as day. She also noted that Ed's right sleeve was flapping in the wind like a flag on a windy day. He's broke his automail again "Hey Winr-" Ed greeted but was interrupted by a rouge wrench flying at his face and he was flung backwards. Ed sat up. "What was that for?!" He screamed. Ed, Al and Roy continued into the house. Ed took off his jacket and pants so they could look at his automail.
"Guess I were wrong you have grown a bit pipsqueak." Pinaco commented as she looked at his leg.
"I can still call you short though." Roy teased, Ed's face turned red from anger.
"DON'T CALL ME SO SHORT HE CAN'T HAVE AUTOMAIL COZ THE SCREWS ARE BIGGER THAN HE HIS!" Ed ranted. Pinaco barely missed Ed's automail leg as he ranted.

Everyone sat at the table for ages eating stew. Stew was always Ed's favorite.
"Granny, Winry." Ed started, the two women looked up at Ed, there was obviously something wrong since he hadn't even eaten half of his meal. "I want to tell you something but...I'm scared of what your reaction will be."
"It's ok, you can tell us Ed" Winry reassured him, giving Ed the confidence to tell them.
"Mustang, the bodyguard that's with me. He's my...my...my...boyfriend" Ed murmured the last part, he didn't want them to think he was a freak. He mumbled it so quietly they almost missed it. Almost. Winry stood up and went round the table. Ed was scared of what she would do, would she slap him, push him out of the door? Winry hugged him.
"It's ok, you thought we would do something bad because you're gay. We don't mind." She said in a sisterly tone. Pinaco didn't say anything but he knew she agreed, she just nodded.

Armstrong

Ed and Roy had a routine of getting lunch, sitting at the table, Roy making fun of Ed's hight, Ed screaming, running off and then they would make out just outside the door of the dining hall. Today was no different. Ed would wait at the door for Roy and then he would walk out.
"Hey, Ed" Roy purred. Ed pulled him out of the way of the window and wrapped his arms around his neck. Roy answered this gesture by wrapping his arms around Ed's back and pulling him into a slow kiss. A tall muscular man walked out of the dining hall at that very moment to witness their make-out session. Armstrong. Alex. Louise. Armstrong. He retreated back to the dining hall and sat with Hawkeye and the rest of Roy's team.
"Hawkeye, did you know about what's happening?" Armstrong asked. They all nodded their heads in unison. Ed walked back into the hall, Mustang was nowhere in sight. Armstrong got up and made his way towards the young alchemist. He grabbed Ed in a bone crunching embrace and lifted him a few feet off the ground.
"OH EDWARD! SUCH BRAVERY TO STRAY FROM THE PATH OF THE NORM AND BECOME GAY! IT IS SUCH A FEAT TO DO THAT, TO DISMISS THE OPINIONS OF OTHERS, SO RESPECTFUL!" He praised. In front of everyone. The young man blushed furiously in embarrassment, so much so that he rivaled the now famous red coat he was wearing. Everyone laughed at this and Mustang walked in on Armstrong's rantings. Ed noticed the door opening and turned his head to face his boyfriend he mouthed the words 'help me' Roy mouthed an apology before slipping out OF the doorway to his office.
