Everything's gonna work out just fine

Do you swear to tell the truth, the whole truth, and nothing but the truth?

I better make sure...just in case.

I went to the front door, not even wasting time on grabbing a jacket.

When I opened the door to step out, Fionna was right there with her fist up, about to knock on the door.

She was in her regular clothes, dripping wet. She didn't even have an umbrella! I hastily pulled her into the house.

"Fionna, what were you thinking? You could have caught a cold, and your leg!" I said, noticing that ruby colored liquid seeping through the bandage wrap.

She just shrugged. "I thought it was kinda refreshing." she said with a weak smile.

'Can you believe this girl? She's almost as nutzo as the Ice Queen. Almost.'

"That's not a very believable excuse, Fi." I said to her.
She didn't respond. She looked pale and sick.

"Hold on just a second, Fi. I'm gonna get something for you." I said, floating up the ladder leading to my bedroom.

I grabbed a towel from the bathroom and a box labeled: Fionna's stuff from the closet.

I came back down into the living room, handing the towel to her and setting the box down.

"Thanks, dude." she said as I turned around to give her a bit of privacy to change.

"Fio, not that I don't enjoy your company, because I most definitely do, but why'd you come visit when it's raining cats and dogs?" I asked, still turned around.

"You came to my house when it was raining. Why is it a big deal if I do the same?"

"Because I'm immune to all mortal sicknesses, you aren't." I said matter-of-factly.

Fionna just sighed. "I needed to talk to you." she said in a sad tone. "I'm finished." she added.

I turned around to see her in the same clothing she was wearing before, but a different and dry pair.

I floated over to her, lifting her up and gently setting her on the couch. "Hold that thought, Fio." I said going into the bathroom to get a first aid kit. I took out a foot stool and lifted her leg onto it.

"What do you need to talk about, Fi?" I asked her while I slowly undid the bloody bandage wrap on her thigh. The wound was still fresh and a bit deep.

"Marsh, are we dating?" she asked.

'What? I thought she was gonna tell me about Gumball. Darn, well, I can't mention it. I want to see if she tells me or not.'
"I don't know, Fi. Are we?" I asked back, putting on a devilish grin and wiggling my brows.

"Pshh I don't know, that's why I asked you!" she said, apparently not really understanding what I was trying to say.

"Well, Fionna, we both really like each other a lot, so yeah, I'd say we are dating." I said, smiling up at her.

'Come on, Fionna. Just tell me the truth. Just tell me about Gumbutt. I'm not gonna be upset with you about it. It wasn't your fault. It was his fault.'

I started to put disinfectant on her wound and began to rewrap it with fresh bandages.

Then Fionna spoke up. "Marshall, something terrible happened a couple of hours ago."

'This must be it. Ok, Marsh, don't show too much anger, she'll think that it's her fault if you do.'

"What is it, Fionna?" I asked, ready for the answer.

She took a deep breath. "I found out that the Ice Queen had been the person that had raised Cake when she was a kitten." she said, trying to fight back the tears.

I floated beside her, sitting on the couch. "Fionna...I'm so sorry. That must be a hell of a heavy load to carry. I just...I'm just so sorry.." I tried to search for words of wisdom, advice, encouragement, anything that would help her. But nothing came.

'Just wonderful. Not only am I a useless friend, but now I'm a useless boyfriend! I'm such a moron.'

I closed my eyes and I could feel her head rest on my chest. I heard her small cries turn into steady breathes and calm sighs.
I ran my fingers through her drying hair, feeling as she relaxed. Those neutral sighs soon turned into ones of affection and I was more than happy to help her to make more those wonderful sounds by brushing my cheeks against hers and interlacing our fingers together.

"Psst, I'm in 'like' with you, Marshall Lee." she said, ending with a giggle.
I couldn't help but let out a few giggles of my own. "I'm in 'like' with you too, Fionna." That, of course, wasn't true.

'The truth was, I'm falling hard for this amazing, magnificent, most beautiful--'

"Marshall, Gumball kissed me."

'Yes! The truth!' I internally yelled. 'I knew that she wouldn't lie to me.'

I gave her a head a sweet kiss and smiled into her hair.
"I'm gonna kill him."
