A/N: Hi, this is my first ever fanfic, and Gumlee is my favorite ship, so I thought I'd give it a try. I hope you guys like it!

*Gumball's POV*

This is it...after weeks of working on it, my anti-aging antidote is almost complete. This was really important, considering that I'm most likely going to be the last in my bloodline. I had no intention of marrying a girl and having children because, even though no one knew about it, I was gay. There was absolutely no way that anyone could know about it, either. With all of the traditional candy people in the Candy Kingdom, I couldn't risk telling anyone without riots forming. Anyway, I just needed to add one more thing. Now let me just go back to my lab...

"BOO!" I heard. I screamed and jumped about three feet into the air.

"What the...?" I thought aloud. There was no sign of anyone. Was my mind playing tricks on me? Maybe it could be the loss of sleep.

I went into my lab to get the secret ingredient that I needed for my antidote. I always keep it in a secure place because of the extreme rarity of the substance. I unlocked the cupboard it was in, only to find it gone! I was completely outraged and confused! There was no way anyone could have taken it, and even if there was, I've been in here for the past three days! No one could have gotten by me without me knowing. I heard something coming from my bedroom, so I went to go check it out. At this point, I was completely scared and was so FREAKING tempted to call the guards. I knew it wasn't my mind playing tricks, someone was here. I flicked on the lightswitch, to find no other than Marshall Lee lounging on my bed with the secret ingredient in his hand.

"MARSHALL LEE! I should have known it was you! Give me that!" I shouted at him.

"Calm down, Gummy." He said, calmly. He was grinning from ear to ear. He tossed me the ingredient and I locked it back into the cupboard it was in. I figured it was him, it only seemed logical because he could turn invisible.

"What are you doing here anyway?" I asked him, quite annoyed.

"Well, I don't have any gigs or parties planned for tonight and I'm bored, so I figured 'Why the hell not?'" he said.

"Hmph, well you can excuse yourself at any time, thank you." I said. It kind of surprised me how he wanted to chill with me instead of Fionna, though. I looked behind me at Marshall, he seemed kind of...sad. That was odd.

"Okay..I'll just get going." he said, dully. Oh glob, I didn't think that would make him upset.

I grabbed his shoulder. "Wait.." I said.

"..I guess we can hangout for a little bit." I said, smiling.

Marshall grinned like a child. "Okay! Come on, I know exactly what we can do." he laughed.

The next thing I knew, I was being carried bridal style and we were floating over the land of Aaa.

"OH MY GLOB I'M GONNA FALL, PUT ME DOWN NOW!" I screamed. Marshall howled with laughter as I clung onto his neck for dear life.

After a couple of minutes, I relaxed. Don't look down, don't look down I thought to myself.

"So...where exactly are we going?" I asked Marshall.

"Um, yeah, about that...I really don't know." he chuckled. Of course.

I sighed and closed my eyes. I think I fell asleep because I was being jolted awake by Marshall.

"Dude, what the heck." he said. I rubbed my eyes.

"Oh, I'm sorry...I'm usually in bed by this time." I said, sleepily.

Marshall smiled. "It's fine, come on." He said. He offered his hand to help me up.

"So, do you know where we're going now?" I asked him.

"Not really, I just thought we'd go through a walk in the Verdant Plains." he said. Fionna and Cake lived around here.

"Hey, maybe we could go see Fionna and Cake!" I said, excitedly.

Marshall stopped walking. He sighed. "Alright, lets go." he said.

I couldn't help thinking that something was bothering Marshall, especially because he wasn't saying anything the whole way there, which took a total of fifteen minutes.

"Um, Marshall?" I asked, "Are you alright?"

Marshall looked like he was in deep thought. I snapped my fingers in front of his face. "Marshall?" I asked.

"Wh- What?" he asked.

"Oh, sorry...I asked if you were alright...?" I said.

He smiled, even though I could tell it wasn't a real smile. "Yeah, I'm fine." I said.

We finally made it to Fionna and Cake's house. I guessed it was around 11pm. As soon as we walked in, we were greeted by the pair.

"Uh..Fi, can I talk to you for a sec?" Marshall asked.

"Sure, Marshy." Fionna said. They went upstairs to talk about whatever it was Marshall needed to talk about. And, for some strange reason, I had a feeling it was about me.

A/N: More chapters coming soon, please review!
