" Zim calm down."

" ZIM WILL NOT CALM DOWN! YOU WERE GOING TO MATE WITH THAT HUMAN!"

[M/N] and Zim walked into the house, that's when the screaming began, on Zim's side most of the time. [M/N] had to shuffle his pants on and rush out, picking up Zim before he could hurt Mateo for the misunderstanding. Now back at home, Zim leaps off [M/N]'s shoulder, falling on his stomach before scrambling to get up. Zim removed his disguise, and began shouting at [M/N].

" Zim I wasn't gonna mat-"

" YOU LIE!"

[M/N] sighs, as he watched the Invader point and scream at him. Usually, this was amusing to him but at this moment, it annoyed him and the pounding at the back of his skull was getting worst. " Zim, please, you need to calm do-"

" ZIM WILL NOT CALM DOWN! YOU CALM DOWN!" Zim snarled as he glared at the Tallest. " ZIM KNOWS MORE OF THE SMELLY-HUMANS! YOU COULD GO A DISEASE FROM EVEN TALKING TO THEM! DO YOU WANT THAT?! WHY ARE YOU EVEN TALKING TO THE PROFESSOR?!" Zim didn't understand why his Tallest would even talk to the male, the only thing they had in common is their height.

" Zim, I got hurt and he was patching me u-" [M/N] tried to explain but Zim only screeched louder, he pressed his fingers against his temples, rubbing against his head. " Zi-"

" DID HE HURT YOU? DID THE DIB HURT YOU? ILL DESTROY HIM!" Zim snarled as he moved towards the door, not caring that his disguise wasn't on but before he could even open the door, a hand grasped Zim's collar and throws him against the couch. Zim huffed about to get up but he stops when a glare was aimed at him. The invader cowards down a bit, antennas down. " My Tallest-"

" Zim, I have enough with your games, your impatient attuide and reckless behavior." [M/N] hissed, he pressed the button on his watch and his disguise, his antennas stretched and some pops of his spine. " Zim, I know what I'm doing, you need to trust me on something's that are my own. I'm not a Smeet or stupid, believe it or not. I may be a smeetary worker but I am still a person who loves company." [M/N] huffed a bit, as he looked at Zim who flinched once his berry-colored eyes meet golden ones. " I am your Tallest, your leader, not your servant, I can talk who I want to talk to and enjoy who I want to enjoy." [M/N] snarled a bit, the pounding at the back of his skull was getting worst. " Just who do you think you are?" [M/N] rubs his head as he glared at the ground now. Oh Irk..this pain...

Zim winced, his antennas folded back a bit. He had never been yelled at by [M/N], if anything, he was scolded lightly but Zim always ignored it. Now, he was being yelled at for something that bothered him, [M/N] was mad at Zim. " Y-Your Smeet..." Zim answers, looking at his gloved hands. " That's who I think..I am..." Zim whispers as he kept his gaze down, a begging chirp was trying to escape his lips but he couldn't, getting yelled at by his Tallest was bad enough. He didn't want to seem weak. " I-I just want to please and protect you.."

[M/N] stared at Zim and noticed the way Zim was acting, almost submissive. His own antennas lowered, Oh Irk, I didn't mean to get mad..I..I..

" Oh Zim.." [M/N] whispers as he sits down on the couch, and looked at Invader. " I-I didn't mean to be so angry..I'm so sorry, I.." [M/N] started, as the headache was slowly numbing, he stared at the sad Irken before slowly pulling the Irken closer to him. Zim didn't try to get out of his touch, he instead nuzzles into [M/N]'s side, his antennas still down. " It's just..felt so..defensive around Mateo.."

" Tomato?" [M/N] chuckles at Zim's response.

" No, Mateo." [M/N] corrected before petting Zim's head, earing a small soft purr in response. " Zim, you do not need to worry with me and him, He is a human and I'm well..a Tallest..plus, mating isn't exactly on my long list to do's right at the moment. I want to go for a walk in the human park, help Dib ride a bike," Zim hissed under his breath but [M/N] ignored it. "And well, I want to do all of this before you take over this planet as it's overlord." Zim looks up, antennas raised and a stupid grin on his face.

" Of course! I will let you have time to do those..human things." Zim said as he tugged at his Tallest's arm, " Though, Zim has one condition about the Dib-smelly.." [M/N] mentally sighs, thinking he almost gotten away with being with Dib. " Zim, I'm not quitting my job just yet."

" Okay, another condition then."

" Okay, what is it?"

" Is this necessary?" Dib asked, as he looked at the pillow tapped against his chest, one on his back. Dib understood why the helmet and knee pads along. He couldn't find any elbow pads in the store so this what they could make do. " I mean, I get the helmet but I'm not gonna shatter my collarbone if I fall." Dib added, " Plus, I still have training wheels on." Dib's bike was black and blue handle-bars. Two smaller wheels on  the sides of the back wheels.

" Oh Dib, of course it's necessary." [M/N] said as he ripes the tape, tucking it against the pillow. Zim played with the frails of his own bike, finding it odd but cute. Zim had took two hours at the store, he wanted the better and perfect bike, better than Dib's. He settled with a light pink one with pony's painted on the sides, with purple frills coming from the handle bars which were pink too. He also had a pink helmet on, knee pads as well but two pillows tapped to his back and front. " I don't want you two getting hurt, you both are my fragile smeets after all." [M/N] mutters to himself.

" What?" Dib asked as [M/N] smiles in response, " Nothing." Dib raised an eyebrow but didn't question him. He looked down at the bike, grasping the handle bars, and pressed his feet to the peddles. He was still nervous, but the excitement overtook the fear. His father didn't teach him how to ride a bike, an actual one, not the big wheel he had. His father was just too busy at work, which was fine. It had to be fine. " Can we start?" Dib asked.

" Hold on Dib, I'm making sure Zim is strapped in." [M/N] said, as he checks over the Invader who grips the handles tightly. He wasn't going to fall, he had training wheels as well. " Gaz, is the camera on?" [M/N] asked the purplenette, who held the camera up, the red button blinking. Without making a sound, she sticks a thumbs up. " Alright, the nice store lady said, you guys just need to practice with the training wheels for a while, build up the confidence before trying without." [M/N] said, as he looked over the two. " Just a practice run."

" How..How do we move?" Zim asked, as he looked around, for something to signal how to start the bike. He looked over to Dib and noticed his legs were on the pedals, slowly he pressed his feet against the pedals which surprised him a bit when the pedals went down in one direction, and up in the other. The bike moved an inch and Zim chirps a bit in surprise. So this is how the human-worm's toy is...Zim..has conquered it! Zim repeated the action and the bike began moving, the grip on the bike handles didn't loosen but he held on as he pedals around.

Dib soon joins the fun, pedaling, mostly going in a circle but still pedaling like Zim. Both boys almost crashed into each other a few times but in the last second, they missed each other, much to Zim's annoyance. [M/N] watched, feeling a sense of proud when they were learning how to ride, especially for Zim, who crackles a bit, and the grin on his face said everything. Zim was having fun, without destroying anything, cutting things open, he was acting like a cute smeet. They look like kids, actual kids, in the beginning they were screaming at each other to either cut them open or to not touch him, now they were trying to run each other with their bikes. They seem so content.

" Daddy!? Daddy?!" Zim breaks beside [M/N], almost falling over but kept his balanced. " Can Zim now ride the bike without these stupid wheels of training? Zim has accomplished the act of riding, now he wants, no, NEEDS to ride without the smeet wheels!" Zim said as he looked at [M/N] who chuckles.

" For once, I'm agreeing." Dib stops behind Zim, looking at [M/N]. " Could we please take the wheels off? I think we're ready, or at least I am." Zim shakes his fist at Dib who sticks his tongue back. " Now, Now, I'll remove them but make sure your feet are planted on the floor, the woman said to." [M/N] said as he grasped the screwdriver and began undoing the smaller wheels from the bike. Zim and Dib did what they were told and watched [M/N] undo the screws, the small legs fall onto the ground.

" Okay, I'll do Dib first. I'll hold on and you'll paddle." [M/N] told the human as he held his hand at the back of the seat, " Hold on." Dib held the handles and began paddling, [M/N] walking behind the male. He watched him paddle, once [M/N] seen he was good enough, he let go and Dib began riding by himself, a bit wobbly but he had good control. " That's wonderful!" [M/N] smiled before walking back to Zim, " Now you just copy Dib." [M/N] said as he began pushing the invader.

Zim grasped the handles tighter, and began paddling slowly, trying to copy Dib, sticking his tongue out in concentration. The Irken soon caught up, and kept going but a hand still held him. " Let go! Daddy, I can do it." Zim said, as he kept paddling, " Daddy?" Zim asked, looking at the Tallest, " I got it. Let go! Let Zim go." [M/N] blinked, a bit and noticed Zim pleading for him to let go. Let go? I guess..

[M/N] lets go and Zim zips off towards Dib who laughs when Zim missed him. The Tallest stared at them, smiling a bit but he felt a bit empty? He had never felt this empty before, he only felt this when Zim was sent off to Invader training. Like this was the last time he would see Zim again, like Zim wasn't going to come home. [M/N] could see him right there on the pink bike, riding around with a joyful expression. He can literally see him, but why would he feel lonely?

" It's called empty-nest syndrome." Gaz said coming up beside the babysitter, holding the camera still. " That's why you didn't let go." Gaz added as she kept the camera on the two boys. " I..I don't have a nest." [M/N] said quietly. Gaz shakes her head, " It means you're not ready for Zim to grow up, or more..or..I don't know How age works. But you think he's gonna leave the nest, or well, home? Ugh, I don't know man." Gaz huffed. It makes sense..I mean..Zim..and I have been close since the day he was made..maybe..that's why he was so angry the other night...that he was losing me...to Mateo and the kids...

" It's painful." [M/N] said, Gaz nods her head, unsquinting one eye to look to him. " I don't like it." 

" You don't have to like it, it's just all about growing up and junk." Gaz shrugs, " You still have us for a fall back plan, if Zim suddenly out grows you." She snickers a bit under her breath. [M/N] perked up a bit, Yeah, I'll still have them, though, they are not my smeets..but perhaps, She's right, this experience would make Zim more independent..

" SUFFER ZIM'S NEW RIDING ABILITY!"

" ZIM WAIT NOOO!" [M/N] and Gaz looked towards the two boys and both sigh, seeing Zim crash into Dib making the human zip off the bike and onto the ground, the Bike beside him. Zim wasn't no better, losing control and falls into the bushes with a scream. His bike on the floor as well.

" On second thought, maybe Zim shouldn't have too much independence." Gaz sighs as [M/N] chuckles a bit as he watched the two boys stand back up shakingly but they went back on their respective bikes. " Maybe a shorter leash?" Gaz joked a bit as [M/N] chuckles a bit. Maybe a shorter leash would work for Zim.

" ZIM STOP TRYING TO HURT ME! YOU BIG FAT JERK!"

" HAHAHAHAHAHAHA!"
