This chapter is dedicated to Mammy Blahsblah, because she said I could stay up late if I dedicated a chapter to her. Also to Jhonen, the nice guy who lets me use his characters.
(PS I get this a lot. Lots of people keep telling me that they have these characters, and want to know if it's OK to still use them. Yes it is. And if you want to put MY Tiz in your story, that's cool too, just tell me so I can read it, K?)

Falling is lots of fun. This was my main thought, dropping a lot faster than I really should have been down the side of a fifteen story building. Dozens of oddly shaped ships whizzed by, parked in the cubicles, but I didn't see them very well. At about the fourth floor, it occurred to me that I should maybe slow down. I did, but I was still going way too fast when I hit the ground.
"I don't feel good," I moaned.
"You shouldn't, idiot. No way you should go that fast," Zim said.
"I was lots of fun," I whined.
"Not having fun now, are you?"
"Noooo…"
"Fine. Dib's over there throwing up if you want to join him"
"No… that's okay, thanks."
Mom dropped to the ground next to me, going easily twice as fast as me. Zim and I gawked as she swiftly tied all the harnesses to the rope and sent hem back up to the ship for whoever wanted to use them next. We thought it best not to ask how she did it.
After waiting a few minutes for Dib, we set off into the city. It was all we could do to stay together. I was just glad we left GIR in the ship. He would have been everywhere.
I sped up to walk next to Zim.
"Why are we here, anyway?" I asked.
"Someone owes me a favor, I think it's time he paid me off," Zim said. I wondered why Zim would know anyone in this place, but didn't ask.
People kept jumping in front of us, waving assorted goods in our faces and proclaiming that their prices were lower than everyone else's. This is impossible, but they didn't seem to know it. Zim glared at them, and they left him alone, and me because I was with him. Mom, waking a bit behind, seemed to be invisible, the same way she had been on Earth, but Dib kept getting attacked by people. It seemed as if they were gravitating toward him. Several times we lost sight of him, and had to wait until he fought his way out of the crowd. Finally we reached a particularly run down stall, which looked almost the same as every other one, except for one difference. The person running it was a human. A seemingly bionetic human, but still human.
"How did…" Dib started, but Zim shushed him.
"This is a friend of mine, not yours. He's nice enough, but if you piss him off, he'll steal your soul and leave you in eternal pain and suffering. Do not say a word unless I say so." He turned back to the booth, where the man was just getting done with a rough, biker-looking guy.
"Hey, Jhonen," Zim said. Jhonen looked at him sideways. His eyes glowed weirdly. I wish I could do that.
"How do you know who I am?" he asked suspiciously.
"You remember me, don't play stupid."
"No I don't."
"Zim. Invader Zim."
"Oh… you got taller. Prove it's you."
Zim sighed.
"Oh, Jhonen, you wouldn't believe the glory that was ZIIIIIIIIIIM'S! The Tallest bestowed on me a BATTLE TANK, which I used to WREAK HAVOK on the filthy, filth-head of the stinking EARTH MOOONKIIIIIIIIES!"
This was accompanied by much flailing and body language. Jhonen looked vaguely amused.
"Oh, yeah. Hey, did you get around to killing that giant-headed weenie human yet?" Zim liked uncomfortable.
"Erm… no. He's actually over there." He pointed in the general direction of Dib.
"Oh. Well this must be embarrassing for you, eh?"
"Yeah. It kind of is."
"Who are these two others then? Are they buggin you? Can I kill them?"
"No, please don't."
"Drat. Been weeks since I killed anybody."
"Yeah, eh… This is Gaz, my leara. And this is Tiz. He's my kid apparently."
"Glad to see you finally found someone who could tolerate your presence."
"Me too," Zim shifted uncomfortably. "As I remember it, you owed me something when I last left."
"Oh, yeah. I was hoping you forgot."
"Do you have it?"
Jhonen smiled a scary grin, stepping back into the back of the booth. He held aside a dirty cloth, which was falling across the doorway into the back.
"Step into my office."

Dat eb all tehre is for now. I may write more, but I need prompting. GIANT HINT HINT!
