Zenn had been on Earth for 3 years now, STILL in love with Zim. But then something horrible happened: Dib came. He didn't like Zenn anymore. But he decided to make Zim mad, and KILL HER. So, he did. He stabbed her and ripped off her Pak when she came to visit Gaz. (They were friends) Zim and Gaz attended her funeral. It was sad. Zim wrote a little note and left it on her Earth grave:
Dear Zenn,
I am sorry about Dib. He wanted to make me mad. And he didn't. He made me sad. I wish you were still alive. I wish I could see you again. All I can say is, I love you Zenn. I think I am going to go crazy. I really don't know why. So I love you Zenn, I guess this is goodbye.
