*3 Years Later...*

"Hold still." Gumball ordered as he fixed Marshall's tie. Marshall craned his neck around him. "She's not here."

"Clearly. Now, listen, and hold still."

"You don't think she'd back out?" Marshall asked worriedly.

"I wouldn't blame her if she did, but no. She loves you, and you love her. This is going to be a wonderful wedding."

"You think so?" Marshall asked.

"Well, you didn't burst into flame as soon as you stepped foot inside of the church, and that was really the worst thing that could happen. And far more likely than either of you running off, so the worst part's over."

"What if I mess it up?"

"Your marriage as a whole, or the vows? Because if she's still marrying you after that incident three years ago—"

"I thought we were past that!"

"—I think you're pretty much never going to mess up as badly as that, so don't worry about it. And the vows are small compared to the rest of your life." He patted Marshall on the shoulder. "But try not to mess it up, or you may accidentally not get married. Running away will also come across as a bad sign. And throwing up. Just try to function like a normal human being."

Marshall shot him a look. "You are terrible at pep talks. If anything, I think that made it worse."

Gumball nodded. "Understood. But stuttering or getting your vows wrong isn't so bad. Just don't forget Fionna's name, okay? Remember, you're marrying Fionna. Calling her by any other name will not be as sweet, no matter what that quote says."

"I know who I'm marrying, Gumbutt! And this is not a sitcom!" Marshall snapped.

"Are you less nervous?" Gumball pressed.

"More annoyed, yes!"

"Excellent. And now you're not going to freak out at your wedding, and the day is saved."

"Yeah, yeah. Where is she? People are starting to come in."

"Yes, that's the point. You don't get married before the guests arrive. That would be stupid." Gumball deadpanned. "Everything's fine. Look, do you want me to go check on her to make sure she hasn't climbed out the window or whatever your irrational fear is?"

"That would be nice." Marshall sighed. "And thank you for being my best man."

"No problem. It's a job I would most likely call upon you for were our situations reversed."

"Wait a—" Gumball was already striding away.

He knocked on the door that Fionna was behind. "Are you alright in there?" The door opened slightly, and he was ushered in. Fionna was sitting at a dressing table, her hair being pinned up.

"Marshall is getting antsy." Gumball commented. "I think we'll be ready to start the ceremony soon."

Cake shook her head. "We still have to finish her hair."

"I don't even... why does that matter? I like me the way I am, Marshall likes me the way I am—" Fionna interjected.

"Weddings aren't about the bride or groom." Gumball snorted. "They're about everyone else. It's like putting on a show for them. So of course you have to look your very best." Fionna shot him a look, and he shrugged. "I didn't write the rules. Are you feeling nervous?"

"A little." She admitted.

"That's normal." Cake said sagely, sticking a pin in Fionna's hair. "Especially since you're marrying—"

"Shh!" Gumball said abruptly. "That's as bad of a pep talk as me telling Marshall it would be a bad sign if he throws up!"

"...did you seriously do that?" Fionna laughed.

Gumball shrugged. "He can't be coddled, he'll abuse the privilege. We all know that."

Fionna shook her head, smiling. "I'll be out soon."

"Fair enough. I'll be sure to tell him."

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

Fionna practically floated down the aisle, Cake by her side. "...damn." Marshall whispered. Gumball elbowed him. "Stop drooling. This is a respectable establishment. They don't need your saliva all over the carpet. And don't swear in church." Marshall shot him a look, then turned his attention back to Fionna as she reached them.

"Dearly beloved, we are gathered here today to celebrate the marriage of Fionna Emily Mertons and Marshall Lee Abadeer..." The priest began. Gumball checked his watch, and his eyes met Cake's, whereupon they both slightly grimaced, while Marshall took Fionna's hand in his.

"Marriage is one of the cornerstones of society... it is the sacred bond between two people, the greatest significance of any love..." The priest continued. Gumball muttered something about taxes, but Marshall and Fionna didn't pay any attention to him.

"You look amazing." Marshall murmured to Fionna.

"You're not so bad yourself." She whispered back.

"...marriage is one of the most important ceremonies of our lives. It is built on friendship, compatibility, and most importantly, love." The priest droned. "Do you have the rings?" Gumball nodded, startled by the fact that the priest had suddenly spoken to him, before passing Marshall two simple golden bands, one of which was then passed to Fionna.

"Do you, Marshall Lee Abadeer, take this woman to be your lawfully wedded wife, through sickness and through health, through poverty and through wealth, through whatever trials and tribulations may come your way, until death do you part?"

"I do. Wait, do I have to repeat all of that?" Marshall asked, tearing his eyes away from Fionna.

"Yes." Marshall nodded once, then repeated the priest's words, slipping Fionna's ring on her finger. "And do you, Fionna Emily Mertons, take this man to be your lawfully wedded husband, through sickness and through health—" At this point, most of the congregation, besides Marshall and Fionna, tuned the priest out, if they hadn't already done so.

"I do." Fionna said confidently, before repeating after the priest and slipping Marshall's ring onto his finger. "Please sign here... and you here, sir..." The priest motioned to the marriage certificate, before announcing, "I now pronounce you husband and wife. You may kiss the bride." They didn't have to be told twice.

However, when it stretched a bit long, Gumball deadpanned, "He said kiss the bride, not to make-out like teenagers. We have a reception to get to, and presumably that's what honeymoons are for."

Of course, this led to Marshall and Fionna finally breaking apart, and the congregation moving to the reception. "...I'm going to have to make a speech, aren't I?" Gumball sighed as everyone filed out of the church, before following them.

*Author's Note*

Look at my abilities to portray weddings as a thing that happens. I'm so proud of myself. I'm not sure if I've ever done that in any of my Fiolee stories. So proud.

And since I had no Blake to be my sarcastic take-no-crap character, who says things like Gumball's pep talk, I had to substitute with the next best thing... so that's why Gumball might be a little out of character. Anyway, I hope that you guys enjoyed this.
