Hello everyone here is chapter 2 of Adventures United; sorry it's taken me so long to update, I am part of my school play until March 24th – my birthday, ugh – so I'll be pretty busy for awhile, but I will do the best I can to write as quickly as possible. Enjoy everyone and please review! :P

A/N: Check out my Tumblr blog (username is same as FanFiction, there is also a link on my profile) for visual aid while reading Part 2; remember: the animation for Part 2 is Anime as a Wizard of Oz affect, but you do not have to imagine it in Anime if you do not want to, know that the animation will change back to it's original form in Part 3, thanks! :D

Chapter 2:

"Strangeness and Charm"

Fionna crawled into bed and turned of her red bedside lamp, letting the natural light of the moon illuminate the darkened room. Tomorrow would certainly be an adventure for both Finn and Fionna, and as usual they had no idea what to even expect what would happen next.

~A~U~A~

The following morning was precisely what Jonathan had promised the night before: very early, not to mention exhausting with dash of annoyance and a handful of depression; the fatigue from waking so early had Finn practically rolling out of bed. Catching himself before he hit the ground, the sleepy boy stumbled over to his closet to pick out the first thing he saw, not really caring what it was. He pulled out a thin, blue pullover hoodie, he shrugged and just decided to wear as a shirt; the small degree of tightness emphasized the muscles of his slightly toned upper body. In the closet was also a low dresser where he pulled out a pair of black shorts. Fionna walked into the room as Finn was tying his left shoe moments later. She was leaned against the frame of the bedroom door wearing a thin white jacket, a dark blue tank top, and a navy-blue ruffled miniskirt with white tights underneath, she had also her sea-green satchel bag by her side – Fionna was chic yet conservative.

"You ready to go?" She pushed away from the doorframe. "Oh and we need to walk over to the pet store to get Cake some catnip after school."

"She wants you to pay her with catnip, Jake wants me to make him a sandwich." They were walking down the hall to the door.

"Lucky, I'll have to Google how to make catnip 'cause, like, I am not spending my allowance on that stuff!" Fionna made sure their mother was not around to hear her plan.

"Haha – will Cake take anything else?"

"I don't know. Bye Mom see you after school!" Bridget came around the corner in her pajamas and bathrobe.

"Hey you kids want a ride to school?"

"We live right down the street from the school Mom, plus you're not even ready." Finn told her.

"Aw dammit, I forgot you guys are going to the high school now, this is sure gonna take some getting used to, I mean I've been driving you kids to school since Elementary." She sighed, not wanting her kids to know she was stalling them, but she had to let them go. "Okay, uh, go have fun on your first day in the big house, okay, love you!"

"Love you two Mom, bye." They both said hugging her at the same time.

Clouds were scattered across the blue sky, blocking the sun's light whenever a one of them crossed its path. There was a chill in the air, but the twins did not mind it, actually they enjoyed the crispness of the air, apparently so did other several groups of kids walking to school as they were, and one of those kids noticed them as they crossed the street, "Hey Finn, Fi wait up!"

"Hey what's up Susan?" Finn greeted as the tall blonde sophomore came up to walk alongside with them.

"Nothing much, how about you guys, I read on Twitter that you guys woke up, like, a week before school started! Aw that freakin' sucks that you guys basically missed the entire summer!"

"Ugh I know right, so how was your summer?" Fionna asked.

"Umm, well I didn't really do much at all other than try out for the girls varsity soccer team, which I made!"

"Ooh congratulations!" Finn gave her a high-five.

"Thanks – oh hey did you guys hear about Johnny Perez?"

"No who's that?" Fionna asked, recognizing the last name however.

"He was Larissa's older brother, he was a senior so that's why you guys probably don't know him. So anyways –"

"Wait Larissa Perez, as in like LSP?" Finn stopped on the sidewalk and so did Fionna and Susan.

"Yeah I think so, is she that snobby chick with the really light purple hair?" Fionna nodded in reply. "Then yeah. Anyways, as I was saying, her older brother Johnny dropped off the face of the planet, and the cops have no clue what happened. Rumor has it that the cops fallowed his trail, then it just ended, but instead of a dead end they found this huge circle that the cops think was some sort of Wiccan weirdness or whatever. I think he went missing at around the end of June. Hey listen I'll see you guys at lunch, or class if we have one together, don't you guys have Algebra 2 this year since you took Geometry in eighth grade, you little nerds."

"Whatever, 'kay see ya' Susan!" Fionna gave her friend a hug.

"See you later, maybe." Susan hopped over the low chain linked fence to run across the football field.

Finn and Fionna continued walking to the front entrance of the school by going through the teachers' parking lot, "So do you think that Johnny was Lumpy Space Prince, it makes sense since Larissa's initials are L-S-P."

"Who knows, but man that's crazy though, wherever he is I hope he's okay –" Finn was cut off when someone walked into him, by this time they were at the steps of the front entrance.

"Move the fuck out of the way freshmen!" A sophomore said coldly to them.

Marceline Abadeer looked down on at the two kids whom she barely knew in irritation, her coal black eyes burning a hole straight through their souls; who was this girl, clearly she was the Marceline they once knew back in the land of Ooo, yet she had turned bitter. The eldest Abadeer twin wore a blood red strapless dress and a pair of faded grey jeans that were ripped at the knees and a pair of red ankle boots, slung over her bare right shoulder was a brand new GIR backpack. Fionna noticed the dark shadows underneath he friend's eyes, most likely due to sleep deprivation, Fionna sighed a breath of relief knowing that rekindling the friendship the three of them once had was still a possibility. In the time it took for Fionna to note the cause of Marceline's crankiness, about seven seconds had passed, and Marceline was not in a patient mood.

"Well are you idiots gonna stare at me like a couple of dumbasses or are you gonna get the hell out of my way!" Marceline hissed.

"Sorry Marceline." Finn sputtered nervously, he did used to have a crush on her too, many moons ago.

"Better be you little shit." She spat then shoved passed him since he had not moved quickly enough.

"Calm your tits Marci, leave 'em alone!" Marshall made Finn and Fionna jump when he spoke from behind them, his sister gave him her middle finger for his comment. The Mertens twins and the Abadeer twins did not know each other well in this life, just names; yet Fionna practically spun around in a single second so she could see one of her best friends from Aaa alive and well, but was taken aback by his… physical appearance. Poor Fionna and her teenage-girl-hormones. This was almost exactly what her Dad had warned her and Finn about the day before – Fionna to be more specific in this case – a teenage boy, a very attractive teenage boy. Like most of the girls at Garfield High did, Fionna could not stop herself from admiring the usually quiet yet friendly boy. Marshall wore a pair of the traditional dark blue jeans and a pair of brown converse, carrying a red Jan Sport backpack in his right hand. What had really startled Fionna was his shirt, his white shirt was thin, extra-small, and long-sleeved; and his sleeves were pushed back below the elbows. Really Marshall is supposed to wear medium sized shirts, yet he unknowingly tormented the girls at school by wearing shirts two sizes smaller his actual size, hugging his toned swimmers' body almost perfectly. Fionna stopped ogling and regained her composer before her acquaintance caught her staring. Ugh, that was her friend from Aaa for Heaven's sake!

"Fuck dammit Marci, sorry about that guys, she's just a little bitchy because she won't stop TEXTING HER BOYFRIEND SLASH MY BEST FRIEND IN THE MIDDLE OF THE NIGHT!" He shouted loud enough for his sister to hear him, she did not turn back though. "Finn and Fionna right, I'm Marshall Abadeer we used to go to middle school together, everyone use to talk about how crazy and cool you guys were. Man has it really been a year since I last saw you two, damn! Aw you two are all grown up now, and you're taller."

"Uhh thanks Marshall, you grew I guess I don't know." Finn said awkwardly

"Yeah I did I'm 5' 11 now, just an inch taller than Gumball." Marshall was proud of himself. "You grew too Finn, what are you now like 5' 7?"

"And a half!" Finn nudged the other boy with his elbow, he could tell re-befriending Marshall would be easy if not Marceline as well.

"Cool, and Fionna you're like 5' 6?"

"Girls don't really care about height like guys do, just as long as we're not super short we're fine." Fiona smirked at him and her brother.

"I'm just gonna go out on a limb here and guess that was a 'yes'." Marshall smirked back.

A car horn interrupted the friendly conversation; they turned to see a yellow Volkswagen Bug: the driver was Bonnibel Mumford, along with her dear cousin Garrison "Gumball" Mumford. As the car rounded the curve to park in the lot, Marshall continued to stare at the car with an anxious smile; Fionna saw his stance, how he had his hands shoved awkwardly in his back pockets, remembering how much he liked her and has since the first grade. Unfortunately for Marshall he was in a relationship already, and with a girl everyone described as "a total bitch!" Most people who knew Marshall suspected the only reason he even tolerated his pompous girlfriend was because he needed someone to get his mind off Bonnibel.

"Hey 'sup buddy?" Gumball smacked his unsuspecting friend's back, a little too hard.

"What the hell!" Marshall playfully punched Gumball in the stomach.

"Ha you can't through these rock-hard abs bitch!" he did the "come at me bro" arms gesture.

"Dude you know I'm more buff than you."

"You're just very cut, it doesn't mean you're buffer than me." Gumball beat his chest with his fist; obviously they had a friendly rivalry about… well, a lot of things – capabilities, appearance, and more – they were more like brothers, and some of us know how competitive brothers can be, actually siblings in general.

"You guys are such dudes, we need to get you both off the swim team before the season starts." Said Bonni, coming up behind Marshall to rest her chin on his shoulder and wrapped her arms around his chest as a hug; Gumball gave Finn and Fionna a knowing look. Marshall however did not react in any other way other than turning his head to give his "friend" a kiss on her forehead slightly covered by her dark red hair; but on the inside Marshall was overwhelmed with joy! "Seriously though you two watch the ego. Hey my little Mertens, how goes it, did you guys enjoy what was left of your vacation? I feel so bad for you guys and how you missed the summer, but did you guys still have fun though?"

"Yeah, actually we're kinda happy to be back at school and with friends," Fionna smiled at her friend she had known since Middle school.

"How are you guys by the way, I heard about the accident!" Bonni let go of Marshall to give Fionna and Finn a hug. "You guys probably never got a chance to, but me and Bubba gave you guys some flowers – they died I think – I have that kind of affect on things. "

"Aw that's okay, and we're doing fine, like I said before we're happy to just be at school and alive!" Finn rolled his eyes at having to be at school.

"Totally, it's nice that you guys have a positive perspective on the whole – ordeal… Ah! What the hell?" The school bell rung just then, the gang stood stayed frozen in place while the other students around them rushed to get to class.

Gumball came up behind Marshall and Bonni to wrap both arms around them to walk up the stairs leading to the main entrance; Finn and Fionna trailed behind them, using their friends and acquaintance as a buffer to avoid crashing into other students – so clever. Before they went their separate ways in the lobby Gumball turned to ask the two freshmen, "Do you guys want to hang out during lunch at our table?"

"What, three sophomores asking two freshmen to eat lunch with them?" Fionna asked in pretend shock. "Isn't it like a rule that freshman don't sit with sophomores, or any other upper classmen?"

"Naw, to hell with that shit, you guys are friends even though I don't know you that well." Marshall smiled at them.

"Sweet, so see you all at lunch, or class if we have any?" Finn asked hopefully.

"Yeah, okay see you guys later, good luck!"

"Oh wait, where's the Main Office?" Finn asked the three sophomores before they were too far.

"Uh… right behind you." Bonni smirked at the confused freshmen, and then laughed along with her cousin and friend when Finn and Fionna jumped in surprise, having found the Main Office was indeed behind them!

"Oh, right." Fionna blushed a deep red and thought to herself, "School just started and we already look like the idiot freshmen, awesome."

"Don't forget to ask for an extra copy of the map!" Marshall laughed disappeared into another hall.

And so begins a new chapter of Finn and Fionna Mertens' young lives, as well as the beginning of life in the year 2012!

~A~U~A~

The first half of the day went by smoothly for the twins, but not once seeing any sign of a familiar face: period one for English Honors, no one; period two for World History Honors, no one; and period three for Biology Honors, again no one. By fourth period for Algebra 2 – a math class Finn was only able to take with the aid of his sister because she, unlike him, understood math – the twins were somewhat discouraged from the thought of having even a single class with at least one of their good friends from the lands of Ooo and Aaa, that was until they saw who were sitting in the back of the class. Sitting in the right corner of the class near the windows was Marshall Lee and Marceline, neither of them was speaking to each other, nor did they look like they wanted to; Marceline was sitting in the desk in front of her brother, and since the class was still mostly empty, Finn and Fionna decided to sit in the two empty desks next to them, Finn sitting by Marshall to avoid Marceline in case she was still angry.

"Oh, well if it isn't my favorite little darlings." Marceline said bitterly, obviously still upset from earlier that day.

"Ease off Marci, don't be mad at them because no one believes your little story about –"

"Shut up loud mouth they don't need to hear this!" Marceline turned in her desk to face him. "And I swear I'm not making this shit up, I know what I saw okay? I'm not just being all paranoid because we used to date!"

"Who did you used to date?" Fionna sat up to lean towards Marceline.

"Nothing it's none of your business… actually I need another girls opinion, and I know you're not a blabber-mouth like most bitches." Marceline leaned closer to Fionna as well, cupping Fionna's ear so she could listen better.

"What, no way, she's seriously dating Creampuff, but why?"

"So you believe me right, it's totally like him to do that, like, I'm not the first girl he's ever cheated on!"

"So Bonni is dating Danny Lewis from varsity football right, he's a junior this year too… wait why do they call him Creampuff again?"

Marshall answered this time, "Because he was caught playing with his supposed nine-incher in the buys bathroom during lunch, get it, cream puff, 'cause like –"

"Yeah, yeah, yeah, yeah, yeah I get it now so don't get into full detail or anything!" Fionna quickly waved her hands before he could mentally scar her.

"Wait I don't get what's happening, give me some deats!"

"Ugh fine I guess I'll tell you, so like –" Marceline was cut off by a obnoxiously loud voice.

"O-M-G you guys have this class too?" Sang a beautiful freshman with long, wavy, light-purple hair; at this school she was called by her initials, LSP, which stood for Larissa Sara Perez. "I'm totally gonna sit with you guys!"

"Holy stuff LSP is flippin' hot in this world!" Finn thought as his eyes grew extremely wide, this girl who was once shaped like a cloud was now a human girl!

"Oh hey Finn, what are you staring at?" Larissa winked at him, making him blush a deep red as the class was called to attention.

~A~U~A~

The bell ending fourth period rang at exactly noon, dismissing everyone to lunch; Finn and Fionna, Marshall and Marceline, and Larissa were one of the first few in line for lunch because their Algebra 2 class was right across the hall form one of the many doors that led to the cafeteria. As the five waited in line to pay, Larissa prattled non-stop about how incredible it was to spend the last couple weeks of summer vacation in New York, but it was obvious she was purposely directing the topic of her conversation away from her older brother's disappearance. Larissa continued her story in full detail, barely noticing Marceline as she yanked Finn away from the others.

"Hey Finn my little buddy, why don't you sit with me for awhile so we can catch up?" Marceline had her left arm wrapped around a fearful Finn, leading him to an empty table on the other side of the cafeteria. When they neared the table, Marceline removed her arm to pull out a chair and set her food down; Finn hesitantly sat in the chair across from her. He sat with his arms on the table, having not yet touched his food, and glanced at the others to see they had already sat down at their own table; Marshall was looking at them both, skeptical of what his sister was going to tell him, but Finn gave him a nod of assurance. Marceline noticed Finn and Marshall's exchange, turning her head to get a glimpse of her brother, and then turned back to give Finn a smile that screamed deviousness. "So Finn, you seem like the type who would do anything if there was a noble cause behind it, am I right? Here's the thing: I do not trust Bonni's boyfriend, and Danny couldn't keep his dick in his pants if his life depended on it, which is why you will help me."

Finn narrowed his eyes, "Well what if I don't want to, and you're just being paranoid because he cheated on you – besides, have you even told Bonni yet?"

"Last night I was texting Gumball, but then we kind of got in a text-fight, but we got over it this morning during second period so we're good now; now he told me not to get involved, however, being the good friend I am, I have to tell her somehow."

"Maybe you should listen to Bubba and leave it alone, I'm pretty sure Bonni can handle it herself." Finn grabbed his food, pushed his chair back, and began to walk over to the table where the rest of the gang sat.

"I warned you Finn, you're going to help me and you know why, because you won't really have a choice!" Marceline crossed her arms and legs to show Finn she was confident in her plan.

"Yeah whatever, are you coming to sit with us or what?" Finn called over his shoulder.

"Naw, you go ahead." Marceline twisted her head to give him a friendly smile.

~A~U~A~
