It was their last year of Skool. Zim was even more determined to take over the Eath before the year ended, but one day he does his usual mission report to the tallests- only to hear that he's spent too much time (5 years) trying to take Earth, and is going to be banished there forever. Red and Purple were getting quite annoyed with all the calls from Zim, and honestly could care less for the small Irken. Zim falls in to depression, and Dib finds himself actually caring for the alien.
Zadr! ZimxDib! Smut!! Mpreg!
