Disclaimer: I dont own Fullmetal Alchemist. I do own Katie though.

A/N: Dresses will soon be on my profile

Katie was running around doing last minute details while Riza was in one of the upstairs room of the church chaning into her dress. Katie was already in her bridesmaid dress, her hair pinned up in a simple but elegant style.

"Uncle Roy!" Katie ran over to him, making sure not to trip in the heels, "Where are the rings? I need to give them to Edward,"

"What the-?" Roy stared wide eyed at his niece. "What are you wearing?!"

Katie suddenly looked down at her dress, "What do you mean? Its my Maid of Honor dress..."

"You look about 10 years older. Do you want men to be mauling you?"

"Oh, my god Uncle Roy. The only person here who is slightly near my age is Edward. And trust me you /dont/ have to worry about that. Now, can I have the rings please?"

He sighed. "Fine." He reached into his jacket pocket and handed over the rings.

"Thank you," Katie said, running off to find Edward. After searching for ten minutes she stopped and screamed (extremely loudly), "EDWARD ELRIC GET OVER HERE NOW!"

Someone clamped a hand over Katie's mouth. "SHH! God, I'm right here."

Katie kicked him in his human knee, muttering something that sounded vaguely like 'Let me go'

"Ow!" He let go. "Just what do you want?"

Katie handed him the ring boxes, "Please tell me between yesterday and now you haven't forgotten what your supposed to do," Katie said

"Then I'd be lying." He teased. "Just kidding. I remember."

Katie glared at him, "Edward Elric if you screw up my uncles wedding I will screw up your face," She said, walking off.

Roy sighed. "I'm so nervous! I need a drink."

"No, you dont!" Katie said, "Your not getting drunk before the wedding," She said.

"I wasn't gonna get drunk!"

"Says the man with a lower alcohol tolerance than a monkey," Katie said, walking off, and upstairs to see how Riza was doing.

Riza was looking at herself in the mirror, the dress clinging to her waist elegantly. Her hair was pinned up with small white flowers in it. She was a vision in white. "Oh my god," Katie gasped when she walked in the room, "Riza, you look amazing," Katie smiled, "Or should I say, Aunt Riza,"

Riza smiled. "You have to wait until we both say 'I do' before you call me that." She giggled. "Oh what the heck! Yes, 'Aunt Riza'."

Katie giggled, "I better go back down stairs and make sure Uncle Roy isn't trying to find the alcohol," She said.

"There was alcohol in here?!" Riza looked disappointed. "I could've stolen a drink for just 2 seconds."

"Not you too!!" Katie groaned, "And yes, there is. Its for the reception," She said, "And oh. If you have a gun hidden under that dress, take it off," Katie murmured before stepping down the stairs.

Riza frowned. "There goes the fun," she said to herself before taking out her gun from her hiding place.

Katie walked back downstairs, setting off to grab her brother from the church nursery (where he wasn't supposed to be) and find Al, who had volunteered to sit with Kasey during the wedding. After Katie gave Kasey to Al she set off the find her Uncle. It was almost time for the wedding to start.

"Katie," Roy said. "I have to tell you something."

"There you are," Katie said, "What is it Uncle Roy?"

"I just wanna say, Thank you. For everything. I don't know how I'll ever repay you for this. But I will. I promise."

Katie smiled at her uncle, "You already have," She said, "More than you'll ever know. Now get in that chapel," She said.

He laughed nervously. "Yeah. Right. Chapel." The only thing on Roy's mind now was him and Riza saying 'I do' and finally being married.

"You'll be fine! Now go. And if you see Edward tell him to stand by the doors, will you?" She said before running back up the stairs to get Riza.

"Sure thing," he called back.

Katie brought Riza downstairs. The doors to the chapel were shut and all the -insert male bridesmaid- and bridesmaids were waiting by the doors to walk in when the time came.

"Riza, you look absolutely beautiful," Gracia said.

"Thank you, Gracia. You look amazing." Tears started to well up in her eyes.

The music started to play and the doors were opened. As all the groomsmen and bridesmaids filed out Katie gave Riza a final smile before walking down to the alter. Riza took a deep breath and walked down the isle. Katie watched her walk down, then looked to her uncle to see his reaction to his bride wearing his sisters dress

Oh my god Roy thought. She looks amazing. Sis, if you can hear me, please, THANK. YOU. SO. MUCH.

Riza took her place next to Roy at the alter, her smile as wide as ever.

"You look beautiful, Riza," Roy whispered.

Riza felt a small blush creep up her cheeks.

The priest started the ceremony. It was quickly time for the vows.

"Will you, Roy Mustang, have Riza Hawkeye to be your wife? Will you love her, comfort and keep her, and forsaking all other remain true to her as long as you both shall life?" He asked, looking at Roy.

"I do,"

"Will you, Riza Hawkeye, have Roy Mustang to be your husband? Will you love him, comfort and keep him, and forsaking all other remain true to him as long asyou both shall live?" He said, turning to Riza.

"I do,"

"The rings, please," The priest said.

Katie silently promised that if Edward messed this up she would shoot him in the head.

Edward walked down the aisle flawlessly and handed the rings to the almost happily married couple.

Roy took the ring and said sincerely, "With this ring I thee wed, and all my worldly goods I thee endow. In sickness and in health, in poverty or in wealth, 'til death do us part." He slipped the ring onto Riza's finger and looked at her with earnest eyes.

Riza slid the other ring onto Roy's finger, "With this ring I thee wed, and all my worldly goods I thee endow. In sickness and in health, in poverty or in wealth, 'til death do us part."

"I now pronounce you man and wife. You may kiss the bride," Roy smiled and slowly lifted her veil.

"Hurry up and kiss her!" Hughes yelled from his spot beside Roy, as best man.

Roy took Riza and gave her the most passionate kiss of a lifetime.

Katie smiled at the couple, and Edward hollered, causing Katie to choke back a laugh.

Roy looked into Riza's eyes and said, "I love you."

"I love you," She said. People started to filter out to the stairs to throw rice at the newlyweds

"Uh oh," he said, realizing this. "Quick, let's make a run out the back door. Maybe they won't see us."

"Oh no you dont," Katie said, "No way your missing your own reception,"

"I never said that!" Roy said defensively.

Katie laughed, "Just go. The longer you make them wait the harder their gonna throw,"
