Being with Zim was annoying. Your instincts were to get away from him, but you didn't listen due to guilt and you wanted to keep the 'sweet honeybun invader' image. But oh, you regretted it so much.

He basically took advantage of that. Not only that, but using the minimoose and the combined energy of the Membracelts that Dib's dad made to teleport earth into the Irken Armada's flight path just to be noticed. Dib didn't know much about you, but he knew you were with Zim. Well, not the whole 'taking over planet thing', but he assumed that you were the reason his father was in space prison with Gaz. zim, being the absolute selfish prick that he was, framed you for it and Dib, being the gullible person he was, now had you on the run.

"I swear to gosh! I will make you pay! I will make you wish you were never born!" He yelled, chasing behind you and moving his slim legs as fast as he can to get you.
