All right fellow killjoys, let's delve into another installment in "The Substitute From Hell!" Ha HA HA HA aH .

The two were back in the house, Gumball was drinking soda and L was fiddling with the cube. "So, you ready to actually do this?" L said, cracking his fingers. Gumball stood and threw the can out, L placed the suitcase on the coffee table and opened it. "Kid, time for some info in yo noggin, this is subspace! An infinite void that's in between universes, in fact, it has no time. If you spend 10 years in here, no time will pass in your time, and you won't age a bit. So, wanna spend an eternity with me?" Gumball jumped on the coffee table, "It's better than being a loser!" And jumped in. L followed and closed the suitcase.

Gumball yelled as he fell, then suddenly stopped, he saw stones as L floated down. The whole place was pitch black but objects floated around. "So! Before you start anything related on physical defense, you need to conquer mental instability or weakness. First is the Test of Mind, Test of Emotion, Test of Resilience and then actual training. These are so you don't breakdown in the heat of battle, so I will do things like test your reflex time, throw objects at you to get used to pain, insult you in the worst ways imaginable. You can leave now if you have second thoughts." "Some of those are physical, but I will stay" L smirked and declared; "Then let your training BEGIN"

Darwin stepped down the stairs, looking for Gumball. He walked into the kitchen, got some chips and sat on the couch, before he turned on the TV, the suitcase rattled. scared, he was tempted to open it, but ideas flew into his head about what is could be. The first clamp was undone, then the second, and then...

BANG! The two erupted from the suitcase with a explosion. "Whoa! Never saw so many robots have that many bullet holes riddled into them that wasn't my fault." L said, cheerful and went to pick up Gumball. "3 years and yet I can't seem to get that last guy." Gumball jokingly said, Darwin just looked on confused. Gumball looked dirty, scars were light but visible, tufts of fur missing and paws red. L went down to the basement and Gumball plopped on the couch. "Hey buddy, long time, no see!" Gumball said, "You got home 5 minutes ago." Darwin simply replied. Gumball was confused by the different lapses in time, "Hey, Didn't three years pass by?" Gumball call to the basement door. "Did you forget? The briefcase is portal to subspace and doesn't process time normally. It's great when having a nap." L walked to the couch and fell onto the couch, as Darwin turned on the TV.

THE NEXT DAY

Gumball rose from his bed, little more better than other days. He went through his mourning routine as usual, brush, shower, change, eat breakfast or in a different order each day. As he ate breakfast, L walked up into the living room, wearing a red hoodie, red sneakers, jeans and a black t-shirt with a owl on a book for a perch. Nicole noticed his change of clothing and asked, "What's with the new get up?". "Well, me and James are going around town looking at stuff. But since Gumball has a potential to hurt people, I have to watch over him. I'm going to use my car this time because I don't wanna get shot down from people thinking I'm a bird, I can drop em' off for you." Nicole glanced, confused, at Gumball, "I'll explain later" Gumball said. Nicole hesitantly agreed so after breakfast, Gumball, Darwin, Anais and L went outside, where across the street a black 1958 Impala was parked from out of nowhere. "How did that car get there?" Anais questioned, "What do you think? I drove it here, duh. Get in the car."

L starts the car, " Yeah, this baby might be ancient by your standard, but this pulled me through the 50s to the end of the world." The kids sat in the back as L drove through the Elmore Friday morning. Anais was looking outside as Darwin leaned into Gumball, "Be prepared when we get to school, you'll be surprised." Gumball shot a confused glance, but stayed quiet to decipher that cryptic message. L got to the school after 5 minutes of driving. "See you kiddos in a few!" L shouted as driving away. Gumball walked up the stairs, but as he went up one step, the kids on the stairs all turned to him. Gumball stood as the kids just stared at him, until Darwin broke the silence. "Get him!" Darwin declared, when he said that, the students held up tomatoes. They all threw at Gumball, but he rolled away, rebounded on his feet and sprung over the last few stairs onto the doorway.

Gumball proceeded through the school, few minutes later, the locker doors swing open and students aim water guns at Gumball. Gumball was startled but he still jumped back, avoiding the water streams. The streams flew and hit the attacker, mildly wetting them. Gumball continued going through the school, now weary of his surroundings.

The once filled school was dreadfully empty, with even the lights shut off. "Ok... seems like the whole school is into this..." He crept around, looking up stairways, staring at lockers anticipating an ambush. Soon, the silence broke as the lockers flew open, revealing more students. He was met with a flurry of paintballs, Gumball tried to dodge, but due to sheer luck and rapid body movements, he managed to escape with a minimal amount of paint. Gumball thought, You know what? I'll just dash to the classroom, just hope Mr. L isn't in this too. Following the italicized words, he ran through the hallways, little did he know, but more obstacles await him.

More and more things flew past his head, brooms, socks, even Banana Joe's peel. Each time, he'd slide, jump or plow through the objects. "I'm not having the best day back, huh" Gumball tried to cheer himself up while this barrage hit him. After a while, he made it to the door, he wearly opened it, to see... His classmates holding up water guns waiting for him. "Woah, Woah, Woah wait, before you soak me, Darwin, how the heck did you get everyone to play along? This seems to full scale for you to conduct." "Well, I just asked Mr. L what happened to you in the suitcase, he told me of your 'training' and so I got everyone in through Elmore Plus and boom". This seems like a scene from a spy movie. Gumball thought, while thinking of what to eat for lunch. "Are you listening to me?" That snapped Gumball out of his thoughts. "Huh, yeah, pretty much." Darwin sighed and raised his fin, as a signal to aim. Everyone aimed and Gumball closed his eyes to brace for the impact, until...

Gumball was grabbed and thrown aside as the streaks of water flew toward him. The thing that threw him was now soaked and trying not to burst with rage. "You guys got my sweater wet, good job." Mr. L stood in the doorway and the students quickly saw their mistake. They profusely apologize as Mr. L walked to the front. "I'll let it slide, but attempt anything like that again... Being in hell won't be the worst thing you'll experience." As he stated that, Mr. L eyes changed, from grayed out irises to a violent red. The whole class went silent and terrified by that statement and Gumball, still against the wall, was terrified. Mr. L cleared his throat, "I was given a proposition by Principal Brown, to join the school faculty as a full time teacher." The students erupted with joy and Gumball picked himself up from the wall.

"But!" The interjection shut everyone up "That doesn't mean I'll stay forever however, that just means I'll linger for a bit longer. But hey, I'll make the best out of the remaining time I still have." Mr. L looked around as the class continued celebrating. Miss Simian entered the room, surprising everyone. "Ah, I see you already told them, you shouldn't get your hopes up, he starts officially teaching Monday, and I'm still here, so Mr. L, please dismiss yourself." Mr. L still looked surprised but snapped out of it quickly, "Aye Aye Miss Simian, I'll see myself out." Mr. L waved as he stepped out of the classroom and Miss Simian sat in her desk. Gumball pondered, what a great start to this Friday, What more can happen now?

No endcard this time, just a good day from a man from the internet to another random person on the internet.. Whoever's here, thanks for reading or waiting for this... this is kinda just my hobby.
