Estra walked out of the skool. Dib had been telling her about how much Zim annoyed him. Estra was nice and listened. She knew what Zim was. An alien. But Dib knew she knew. And he also knew that she wasn't going to side with him. Because she was already sided with Zim. Dib was fine with this, as long as she listened, he was happy.

She had been assigned to watch over Zim. And she had done so with much force. She made sure he was nice, had taught him manners, and everything else a human should know. For she herself was a human. Dib said he had to go and left. Estra rabbled. Thank the Lord he was gone. She looked up.

Many paces away, almost on the other side of the playground, was Zim. He was being beaten up by an older boy. The boy's name was Carn, he was a huge bully at the school. Estra walked over. He was about to punch Zim when Estra put her hand on his fist.

"Let the kid alone dude," she said simply. Zim had been used to her calling him 'the kid' a lot sense they met. Everyone thought they were siblings. Estra the older, and Zim the younger. And they sure acted like siblings.

Estra and him were always fighting about everything and anything. But Zim had somehow hated that fact that she just saw him as 'the kid' and nothing more. It was almost as if he wanted to know she cared. But he was almost certain she didn't.

"Yeah right," Carn said. He chuckled and tossed Estra away. Estra skidded across the pavement and didn't move for a while. She was in shock, every other boy she had told to leave Zim alone had mumbled something and walked away. But Carn was more of a jerk truth be told. Estra shook her head clear. She looked at the ground. Thinking. Now what?

While she sat there in thought Carn pinned Zim against the fence. His fist grabbed the collar of his shirt. His fist went against his throat, suffocating him. Zim struggled, but it was of no use. The boy was stronger than he.

The boy punched him in every spot he could think of. Zim could hardly breath and hadn't enough strength even to try. Carn laughed evilly. Estra looked up. She glared and stood up. Her hands formed fists.

"Get your hands off of my brother!" she shouted running up to him. Carn looked over at her and hardly had time to gape as she punched him in the face. He looked up at her as he got his balance.

But Estra had made the first move and kicked him in the gut, then she punched him in the jaw, and she was about to hit him again when she heard Zim moan her name. She quickly tossed Carn to the side and ran over to Zim. She moved his hair out of the way and glared over her shoulder at Carn.

"If you touch my little brother again, if you even look at him wrong, I will gut you like a fish!" she said in a low tone. It may have been quiet, but it had much force. "Am I clear?"

"Y-yes," Carn said as his friends helped him stand.

"I'd better be," Estra said. She picked Zim up. His eyes were closed and he was now unconscious. She walked away from the skool and headed home. Dib watched as she walked away. He almost felt worried about Zim. But he shook it off and headed home himself. But it still nagged at the back of his mind as he walked home. Is Zim ok? Dib thought over and over.
