Everything Has a Purpose, an Invader Zim x GN Reader

Zim is Stupid

It's your third day of human school and you're already stuck with Zim, your sworn enemy, and his stupid plan to destroy Earth... or whatever it is he's doing. This is all because you let people walk all over you. You decide not to tell Dib that you're suddenly helping Zim out of your will, the poor kid would absolutely lose it. Instead, you just pretend you have no idea what's going on.

This city is weird.

Stepping into the class, the alien boy rapidly pats a seat beside him. It just so happens to be your assigned seat. Hooray.

You sit down and he just... stares. He just stares at you and it's pissing you off. You raise an eyebrow at him and he looks away, embarrassed. You roll your eyes and focus on the floor; it sure is dirty, huh. You squirm in your seat... what an amazing time to remember you're a germaphobe. You try to take your mind to other places as you try not to vomit. Hmm... what to think about? You brought some snacks for lunch today, maybe you could have some now? When you get home you should contact The Swollen Eyeball about your mi—

Oh.

FUCK.

YOUR MISSION.

You've been here for 3 EARTH DAYS and you're just NOW remembering your mission?? Shit, you need to look over it again. What the hell are you doing here? You pull out your device and look over the text, hiding it as much as possible.

You're apparently supposed to be here to study the life forms and try neutralizing any anomalies you see. So it's not just you, this city truly is weird. From what you gather you could be looking for vampires, ghosts, Greek mythological monsters, aliens. You shudder at the thought of exposing an extraterrestrial like yourself. Now that you think about it, this mission can be dangerous. Really dangerous.

"Hyooman?" Zim's voice startles you, the slightest bit of concern in his tone.

"Oh, haha, hey Zim!" You nervously laugh, slamming the device closed. You cringe; you hope you didn't break it.

He eyes you suspiciously but quickly shrugs it off as your... friend, Dib, enters the classroom and begins shouting. Something dumb, you presume. Zim and Dib begin shouting over you but you couldn't be less interested. Until you're shoved so hard you fall out of your seat.

You're pissed. This seems to happen a lot.

"I'm telling you! Zim is an alien! Even (Y/N) believes me! Right (Y/N)?!" He looks at you with hopeful eyes.

You inhale slowly through gritted teeth.

"Dib," you ball your hands into fists, suppressing the urge to scream. "Zim may be abnormal, I know that, but if you ever fucking shove me again I'll make you a ghost myself. I am not in the mood!"

There is a collective "oooooo" around the class as you sit back down. Seeing Dib's heartbroken expression makes you feel a pang of guilt. Your anger falters immediately and you feel really bad, like really bad. You pull out your phone and text him an apology, grateful that you two had exchanged numbers.

You: I'm sorry Dib, I've just had a bad morning :(

Dib: it's fine really

Dib: you wanna talk about it?

You: maybe later

Dib: ok if you say so

Dib: i'm always here for you :)

You look over at him and smile, he smiles as well. All should be good now. You look over at Zim and he has the shittiest grin on his face. He gazes over at Dib and snickers.
