Gumball was in his office mulling over how to break up with Fionna. He still wants to be friends with her but after what Marshall told him he wonders if it's even a possibility. He has also realized that because they were publically a couple there would be questions from his people. Questions he didn't really know how to answer.
He knows of a few outcomes of the mess he's in. One, Fionna could take it well and things can go back to normal. Two, she could not take it well and avoid him for the rest of her life. Three, if she really hated him she would kill him. Four, if he somehow hurt her more then Marshall would kill him.
He is hoping for the first and preparing for any of the others. He even went as far as to write out who would lead the candy people if he should die. Needless to say, he is very stressed over the situation.
He sent a message to Fionna's house inviting her to a private tea party. No one would be around and he could hopefully explain himself. She could even scream and cry if she needed it.
However, he sent the message a day ago and hasn't heard a reply. He also doesn't want to call, but not knowing is just causing him to freak out more.
"Excuse me, Prince Gumball?"
He jumped, "Yes?"
"Fionna is here to see you."
Now he's freaking out even more, "Great send her in and bring some tea for us please."
She walked in as the maid left, "Hey, sorry I didn't respond to your message. I was with Marshall and the guys most of yesterday."
"It's alright Fionna have a seat."
She sat across from him, "Is everything alright?"
He didn't know how to answer that, so he didn't.
"Bubba, you can tell me."
"Forgive me Fionna I just don't know how to put what I need to say into words."
Fionna wasn't dumb. She knew whatever he was going to say would be bad news.
So she tried to have a different conversation, "Well, while you try and put what you want to say into words can I ask you a question?"
"Sure." He was visibly shaking.
"Is what you want to say about us?" He paled and tried to stutter some kind of response but she continued, "Because a few things have been brought to my attention and I just want to make sense of a few things."
He nodded for her to continue.
"Our relationship hasn't really changed. Other than the party you haven't even tried to do anything with me. People have told me it looks onesided, would you agree?"
"Fionna I am sorry."
"I just want to know why you said yes when I asked you out? If you knew you didn't feel the same you could've just told me."
"It has been brought to my attention that I should have done that."
"So why didn't you?"
"I was hoping to show you I'm not the man you think I am." He sounded so shameful.
"Explain."
"I thought that if I said yes that you would quickly see I'm not the right guy for you. I now see what I did was incredibly stupid and inconsiderate and I am deeply sorry. I can only hope you and Marshall will forgive me in time but I-"
"Marshall? What does he have to do with this?"
Oh shit. He tried to say something, anything, but nothing was coming out of his mouth.
Fionna's confused expression morphed to shock, "You're Asshat..."
Now he was the confused one so she continued.
"Marshall tried to tell me. He tried to warn me, and I didn't see." She chuckled not knowing why "It was so obvious. He didn't like me dating you, the way both of you acted at the party, the way he would ask about us. Glob! I'm an idiot!"
"Fionna please, I-"
"That also means that you think Marshall is the guy for me..."
He was shocked at how much Marshall did tell her but he finally found his voice, "Yes..."
She looked at him. Her eyes were starting to tear up, "You tried to play matchmaker in the absolute worst way possible."
"I am sorry."
"What the Hell did you expect out of this?"
He took a deep breath and tried to explain, "At first I thought I could show you I'm not for you and you'd break up with me. I have been told that things work a bit differently than I thought."
"You really thought no one would get hurt in this?"
"I am not like you and Marshall. I don't feel that romance and I never have. There are not enough words in all the languages to say how deeply sorry I am for hurting you."
She grabbed her head still trying to make sense of it all.
"If you need time I understand. I would still love to have your friendship, but I also see that I have royally fucked up and there's a chance you may never want to see me again."
She started to get up she looked to the door and spoke, "I will need some time to figure some stuff out. I'll still be a hero and help the people of the Candy Kingdom, but don't call me for anything else until I call you."
"I understand. Be safe." With that, she walked through the door and out of his life for a while. The Maid came back in with their tea, "Where did Fionna go?"
"She had to leave if you could get me some whiskey that would be great."
Fionna was back at her treehouse. The first thing she did was cry, the next was call Cake.
She told her everything. She just wanted to vent but her sister decided to come back to the treehouse for a time to help her.
"Cake really I'll be fine."
"Oh I know YOU will be but once I get my claws on that prince HE won't be."
"Cake please." Fionna's eyes were red and puffy. She didn't want any more drama.
"Fine, I won't for your sake." She walked over to her and handed her some movies, "First I am getting you some food, then we are going to watch a movie, then eat some more!"
She glanced at the movies and said, "As long as I don't have to get you out of jail fine."
Cake went to the kitchen and started rummaging for food. She decided to make some bacon pancakes and make a phone call. She knew she needed to be sneaky with her call. She knew Fionna needed space and that Marshall needed to know what happened.
"Hello?"
"Hey I was just callin' to see how the kids are doin'"
"Cake this is Marshall Lee."
"Good glad to hear."
"Cake is everything ok?"
"Yeah I'm fine, but you know Fionna is having a rough time."
"What happened?!"
"I know! Who knew the prince could do something like that? I still wanna sink my claws in him, but Fionna won't let me."
"Oh shit, they finally broke up. How's she handling it?"
"Yeah, our Fi is too good. But you're right she just needs some time. Anyway, I'll be back home in a couple days maybe later. I just wanna make sure she'll be ok."
"She will be. I'll give her anything she needs. Thanks for telling me."
"Good to hear. Talk to you later."
She ended the call and walked back to Fionna with a stack of pancakes, "Did you decide of a movie?"
"Yeah," She held up, Legally Blond.
"Nice choice all ways good to laugh in times like these."
They started watching the movie and were a while in when Fi said, "You know, at first I thought he just didn't know what he felt for me."
"Oh, honey..."
"It hurts so much more know he knew how he felt and still did that."
"It'll be ok, you have me and BMO, and even that vampire. We're here for you."
"Thanks," She sighed, "I don't know how I'm going to face Marshall."
"Same way you always do."
"But I know he likes me. I know that he's amazing but after what he said the other night I know I shouldn't try and date him."
"Don't stress over it. People take their time how they take their time. Who knows you could be completely over Gumball before the end of the week."
"Do you think it can be over that fast?"
"I have met people who take maybe three days to get over an ex."
"How do they do it."
"Well, one girl I asked said she just tells herself 'the Universe had a different plan.' Another one said 'why waste time on someone who's not worth it."
Fionna hummed.
"Don't worry things will get better and you will be ok. Plus I'd say you're already making great progress."
"Really?"
"Yeah, one you chose a comedy when most girls would choose anything else and two you're already thinking about a potential relationship."
Over at Marshall's, he is having his own freakout because he just realized that Fionna knows how he feels about her. Now he doesn't know when a good time to see her would be or if he should see her.
"Boys! I need you guys over at mine quick!"
