I do not own any rights to Adventure Time whatsoever.

I'm going to do more optional chapters that are basically little tidbits of flashbacks or fluff. Since classes are intense, I kinda have to be really slow in updating and stuff, and I really regret not doing this earlier.

Thank you for reading though! Reviews are greatly appreciated~

"You're that Marceline?!", I yelled after the half-second long flashback that felt like a sharp jolt to my heart.

She gave me a devilish grin and confirmed, "Bingo, Hero Princess."

I blushed at the foolishness and absence of shame of my younger self. I started to blush even harder because of what Marceline had said to me as a child. "I'll be your knight", she said.

"Well? Am I cool enough for ya, Bonnie?", she questioned as she tried to display her "coolness" with a pose that seemed oh-so familiar to me. I could feel the blood rushing to my ears and my cheeks overheating. I buried my face in my hands and tried to regain composure. Marceline started laughing, but she soon stopped as soon as I peeked from the spaces in-between my fingers. She smiled at me, walked over to the couch, and sat next to me. I put my hands down to my knees, but I didn't make any eye contact with Marceline. I was still too red, but then a thought came to my mind.

"If you wanted to be my knight, why haven't I seen you since then?", I muttered as I played with my thumbs a little bit.

I didn't see Marceline, but I heard her take in a breath and sigh, "I had family things to deal with. 'Cause of that, we moved, and I didn't come back until, like, sophomore year."

Having my curiosity struck, I turned my head to face my childhood knight. She had a serious look on her face, like the face she made when she was singing only sadder. She didn't even make eye contact with me.

"Wait." I realized, "If you were back sophomore year, why haven't I seen you until now?"

Marceline blushed a little and avoided my face even more. She was out of her serious state though, which made me feel more relaxed. If someone as laid back as Marceline was serious, then something serious was actually happening.

"I-I-I.", she stuttered, "So. I. Uh."

She kept on stalling and blushing even harder.

"You?"

"I. Ugh." She put her elbow on the arm of the chair and propped her head up on her hand. Her long fingers wrapped around her cheek as her palm covered her mouth. She closed her eyes and mumbled something into her hand.

"What?"

She mumbled slightly louder and turned extremely red.

"Marceline, I can't-"

"I thought you were a dude, okay?!", she finally yelled as she stood up and looked at me with clenched fists and shoulders stiff. I thought for a brief moment and remembered how I looked when I was younger. I really did look like a flamboyant boy; almost like Finn only pink and purple. I giggled at the mistake that Marceline made. This caused her to make a little growl.

"How could I not though?!", she snarled.

"I was 'Bonnie the Hero Princess'.", I retorted.

"I still thought you were a dude! Like, you had the short hair and the clothes and the fighting. And. And."

She started to blush again.

"You were the coolest."

I looked at her face and how she stood. She reminded me of a guilty puppy. All I did as a response was smile. That is, until my phone started to ring shortly after.

"Hello?"

"Bonnibel, it's Pepper. It's well after clubs let out, and I'm wondering if you're going to be home for dinner."

I looked at my pink-strapped watch and saw that it was close to six.

"Oh! I completely lost track of time.", I said to both Pepper and Marceline.

I took my bag and started heading out the door, saying a silent goodbye to Marceline who returned my goodbye by mouthing "See you tonight" and giving me her ever-confident smile. It looked like she was back to her old self again.

On my way back to my car, I started thinking about Marceline. Was that why I wasn't as skeptical as I should have been when I saw her come out of the student council closet? When did I forget that she was someone from my childhood? Why did I forget about her? It might have to do with the fact that she just left out of nowhere and never came back until recently. How did she get the "Queen" nickname? If anything, she was the first person my age to be saved by me. She was,

"My first princess. . .", I whispered out loud as I buckled my seatbelt. I became completely flustered at the thought and hit my head on the steering wheel. I never felt more embarrassed in my life. I was just red all over. Then, that's when I heard someone singing right outside of my open car window.

"I'm gonna

drink the red

from your pretty, pink face.

I'm gonna

sink my fangs

in, and make your heart race."

It was Marceline underneath a biker helmet that covered her mouth. She got onto the mysterious vehicle from earlier this morning, started it, put her visor down, and rode it skillfully out of the parking lot. I'm guessing she didn't notice me; otherwise, she would've probably said something. Maybe she did know that I was there and was just teasing me with that song because she saw the red blaring from the tips of my ears. Maybe. Ugh. She's the most frustrating piece of work I've ever met!

However, that little song did make my heart race.

Original part of the song belongs to Adventure Time staff. The last two lines of it I just made up. At least, I think I made it up. I never heard someone fill it in even though I bet a ton of people already did on YouTube.
