This one's actually kind of short. Sorry.

Mia was furious. As she dragged Zim behind her to his house, the rain let up. Hey, the rain stopped, the Irken realized.
"Mia-stink, I no longer require your assistance. The rain has stopped and-"
"Did you just call me 'Mia-stink'?" She whipped around to face the green teenager behind her.
"Um, no, I called you… Mia?" he covered hesitantly. She started to calm down, then she threw him inside his open door.
"TACO!" Mia heard from inside the house. Freaky family. She walked in, but only because she was bored and wasn't assigned homework. Some sort of furry thing attacked her face screaming, "HI, MUFFIN-PERSON!" She ripped the thing off and threw it at the other end of the room. Instead of hearing a thud, like she expected, she heard a CLANG! This house is CRAZY! She thought. She sat down on a couch next to her. Zim walked back in the room, without his disguise, and saw the blind HYOOMAN on his couch and froze. Then he relaxed a bit. She can't see me, he remembered.
"But I can hear you, dude," she reminded him. Did I just say that out loud? The Irken wondered. "Yes, and it's pretty freaking annoying."
"Damn," the Irken cursed.
"Whatever. What was the fuzzy thing that attacked me? I threw it on your wall," she said.
"That was my completely normal dog, Gir," Zim lied. "He likes people."
"Last time I checked, dogs don't talk."
"Uh…."
Mia stood up and walked to where she heard Zim's voice coming from. She reached her arm out and Zim worried she was going to punch him. But instead, she touched his face and traced it with her hand. She ran it down his cheek and onto his neck. Then she pulled away.
"What was that?" Zim freaked out.
"Calm down, Zim. That's how I see. With my fingers," Mia explained, and reached above his head to feel his hair. Wait, he didn't have hair. Her sightless eyes widened, and Zim groaned. She wrapped her fingers onto his antennae and gasped, "What the hell are you?"
"Uh, funny thing, that, heh heh. SECURITY!" he screamed, and Mia felt herself grabbed by something cold and metallic and was hoisted into the air.
"LET ME GO!" She shouted. "Let me go, Zim, or you're gonna die!"
"Is that a threat?" he hissed.
"No, I-" Mia was cut off as Dib busted down the door and saw Zim and Mia, who was being held captive by giant steel cables.
"Mia!" he yelled. "I told you so!"
Dib tackled Zim and they started fighting. Somehow, Mia had slipped out of her bonds and out the door, unseen by either of them. That was close. They almost found out she was a Gateway.
