SPOILER WARNING OF DOOM: This section or article may contain spoilers!
This episode was to shed light on Zim's past (and a small bit of the Tallests', too). Throughout it, all the destruction Zim caused prior to Operation Impending Doom I is revealed, including plunging Irk into darkness twice, killing two leaders (Almighty Tallest Miyuki and Almighty Tallest Spork), and destroying a substantial amount of Irk's surface.
In the end, all the bad data from Zim's PAK would have caused the Control Brains to declare Zim the "Most Incredible Irken Ever" and let him drive the Massive for ten minutes, much to the Tallests' dismay.
End of Spoilers: There are no further spoilers for this section or article. You can breathe now.
