EDIT: THE TITLE WILL BE CHANGED ON 7 AUG 11 TO 'The Perfect Drug'. This isn't a song-fic, I promise. I think that title fits better honestly.

I am surely alive… And filled with goo! XD Aheh, yeah. I'm back… While waiting for Assassin's Creed: Revelations, I've decided to take up an old habit. Or obsession. Perhaps Zim invaded my life again? :D So, not what I normally write, but expect more random parings. If you don't like ZaDr, then please don't read or flame (I mean, seriously. I wrote about Ezio/Leonardo. You gotta expect an M/M from me in this show too. XD). And rated M, because that's what I'm used to writing. I don't own Assassin's Creed and I don't own Invader Zim (But if I did, that show would surely be back on the air! :D).

I didn't know what I was feeling… My dad said something to me about the birds and bees, but… it was one of those pre-recorded things… Damn him and his job. Always busy. I stared at myself in the mirror, my complexion unfriendly today. I poked at the acne, combed my hair, then walked downstairs to the kitchen. I was too big for the chute above the sink now. I chuckled, thinking back to being a child. Always trying to show Zim for the Irken he was.

"Speaking of Zim… I haven't seen him in years… wonder what happened to him…" Dib sat down at the table and began eating the cereal he prepared.

"Brush your teeth, and Gaz, feed the puppy." The recorded message echoed in the house.

"If we still had that puppy, she'd be dead by now." Gaz sighed, walking into the kitchen. "Dib, you're eating my cereal…"

Dib looked at the cereal. "Oh shiat…"

Gaz's eyes narrowed.

"W-wait Gaz!" Dib stood up hastily, knocking the cereal to the floor.

"And now you've wasted it…" Gaz's left eye opened, her dark pupil glaring into Dib's soul.

"Fug…" Dib looked at the wet floor.

One of the cleaning bots came and cleaned up the mess, returning the bowl to the table.

Dib sighed. "I miss dad."

Gaz didn't back off. "You… will… pay…"

"No, seriously. Look at us. He's never around, we take care of ourselves – We've been doing that since elementary school. And who spells school with a 'k'?"

Gaz looked around. "Yeah… I guess that's kinda dumb."

"I'm sorry Gaz."

Gaz sighed. "Eh, I guess it's okay."

"I haven't seen Zim around, have you?"

"No, I haven't…" Gaz shook her head.

"I'm going over to Zim's."

"He hasn't been there for years, what makes you think he'll be there now?"

"I… I don't know. But while I'm out, I'll buy you some more cereal."

"Okay." Gaz shrugged and sat down, pouring the rest of her cereal in a bowl.

The green house looked run-down. No one had been there in years, Dib approached the fence, the gate open. He looked at the garden gnomes, throwing a rock near them, to see if they shot. They didn't. He cautiously walked past the gnomes, up to the door, now noticing it was ajar. He roiled his brows and walked inside. Wires were torn and falling, some sparks emitted every once in a while. Dib remembered the trash can was a way into the lab, and he stumbled down into it. When he finally was able to stand up again, he looked around. A dark red ambience seemed to fill the lab. He heard some groaning in the back, and began towards it. "Zim?"

Someone gasped.

"Zim, are you here?" He turned a corner. Suddenly a loud crash scared Dib, and he jumped backwards. "Who's there?"

"Worm…baby…"

Dib's ears perked (He imagined how Zim's antennae perk when he's alarmed.), and he ran towards the pile that had fallen. "Zim! Oh my god, are you okay?"

"Why…" Zim hissed, his skin pale. "Why do you care?"

Dib observed Zim. He was just as small as he was when they first met. His PAK was plugged into the computer, but no power seemed to be going to the PAK. "How long have you been here?"

"Four of your Earth years… Computer… lost power. Zim can… barely get… any power to… PAK…" Zim gasped for the air his PAK failed to filter.

"Zim, let me take you to my lab! I can he-"

"Why!" Zim hissed again. "You're just… another human worm-baby… Why do you care?"

"Zim, please."

"Invaders… need help from… no one…"

Dib sighed. "Alright. Have it your way." Dib shrugged and began to leave.

Zim blinked. "W-wait, Dib-stink."

Dib turned around. "Yeah?"

"Can you… find a way… to power Zim's… computer? Or at least Zim's… PAK… so Zim can survive coming to… your lab?" Zim gasped.

"Yeah. I'll be back." Dib nodded.

"Gaz! I found Zim! He's injured! I need your help!"

"Where's my cereal?"

Dib blinked. "I'll get it after we get Zim here."

"Alright." Gaz sighed. "I guess…"

"Zim? Are you still here?"

"Where do you think Zim'd go?" Zim hissed.

"Aheh… sorry. Here, plug your PAK into this."

Zim looked at the device Dib brought. "I don't know if I can survive disconnecting from the computer…"

"Isn't there another thing you could plug into this?"

Zim blinked, and a hatch opened on his PAK. "Take that… cord and plug it in…"

Dib obeyed, plugging it into the device.

After about two minutes, Zim gasped suddenly. "I… I can breathe!" Zim exclaimed. "I AM ZIM!"

Dib chuckled.

Zim looked at Dib, then disconnected himself from the computer. "How long will this last?"

"An hour." Dib said. "Let's go."

"Wait, I need to-"

"No time. Recharge at my house, then you can come back."

Zim sighed. "Alright, Dib-stink."

Zim sat down, Dib's computer recharging his PAK.

"Can it even hold a charge anymore?"

"I don't know…" Zim sighed. "My Voot Cruiser is ruined…"

"I still have Tak's ship." Dib said.

Zim looked at Dib, surprised. "Still?"

"Yeah."

"Why are you helping Zim? Dib-stink?" Zim stared intently, his crimson eyes glowing.

Dib blinked. "Well… I…"

"Out with it!"

"I don't know… I just feel like I should help you."

Zim stared at Dib. "Why?"

Dib shrugged. "So, I guess after you recharge, you're going to return to destroying Earth?"

Zim's eyes lost the life Dib had given them. "No… Zim is no invader…"

"What? But you just said today that an invader needs help from no one."

"Zim took your help, didn't he?"

"Well, yeah, but you would've died if you didn't."

"Invaders need help from no one. Zim needs help from you. Zim is no invader."

Dib sighed. "Oh… Well. I… Um… Shit."

Zim looked at Dib. "Dib-human, you've grown quite a bit."

"Humans have a thing called puberty."

"Yes, Zim knows this." Zim nodded. "You're taller than me…"

"Yeah. Growth spurt."

"Zim knows this!" Zim exclaimed, but the life left again. "Zim is so short…"

"Maybe you'll grow some."

"No. If Zim were to grow more, that would mean he would be as young as you, Dib-meat. Zim is over 100 of

your Earth Years old."

Dib blinked. "Whoah…"

Zim nodded. He looked at his PAK. "Zim remember when you almost died, trying to steal Zim's PAK."

"You almost died too."

"You didn't care then."

"But I do now."

"Explain to Zim why you care! Zim doesn't understand!" Zim jumped up on the chair and grabbed Dib's trench coat, shaking him furiously.

"I can't explain it… I don't know why Zim, but I can't explain it! You were missing for four years, back then I would've loved that, but now… I've changed more than just physically Zim."

Zim blinked and turned loose of the coat. He sat down again, looking up again at Dib. "How else? Besides caring for your enemy? Now you'd definitely be a horrible soldier."

Dib shrugged off the insult. "Zim, I don't want you to be my enemy anymore. I'm tired of fighting you – I did enjoy the time you were missing…" Dib noticed the twitch of Zim's antennae. "but not for the glee of you missing. I enjoyed not fighting you… and now that I found you, I don't want to fight you. And you said you're not going to destroy Earth anymore anyway… So why bother fighting over a planet we both are going to live on?"

Zim's antennae dropped. He looked down to the ground, broken.

"Are you okay?"

Suddenly Zim looked up at Dib, smiling. "Zim is better than okay!"

Dib roiled his brows. "You sure?"

"Zim is sure."

Dib smiled. It was the first time he had seen Zim smile in years. And it wasn't the evil smile he normally wore. Dib realized this was the first time he had ever seen Zim smile, genuinely.

"What are you staring at?" Zim asked.

"Nothing." Dib shook his head. "So, are we friends?" He stuck his hand out for Zim.

"Whoah-whoah-whoah! No. Aquaintances?" Zim asked.

"Alright, fine. Aquiantances." Dib nodded.

Zim shook Dib's hand.

"Good. So tomorrow we can go get your stuff you need from your base."

Zim nodded.
