Lobotomy (A ZaDr Fanfiction)

After Dib finally breaks and tries to stab Zim in the eye with a scalpel during science class, Zim dodges, but ends up stabbing Dib through the hand with his scalpel. After this aggravated assault, started by Dib as Zim's robot parents somehow testified against Dib in court, he got sent to a psychologist who decided there was little to no hope for Dib, there being only one exception: lobotomy. They decided enough was enough about Dib's constant rambling about the paranormal and aliens, so they chopped part of his brain off, in turn killing his motivation all most entirely and effectively and completely changing Dib's personality. The once exited kid became little more than a few quiet statements, and most everyone was happy. Everyone but Zim. Dib, losing motivation for even exchanging anything for the alien, not to mention how Zim didn't know what a 'lobotomy' was, caused him to get angry, and try to start fights with Dib, that never got acknowledged. How will this effect them?
