A/N: There'll be one more chapter after this one, with our best friend Dib. But for now...Read on.
"Fine fine, entertain me." With a wave of his hand, Zim permitted Dib to speak again. Swallowing around a lump in his throat, Dib spoke.
"W-well...I think you're a worthy adversary, too, and-"
"It's true."
"But that's not the point. You see...the first day you came to Skool, my life changed. Finally, proof of everything I had been telling people for years! A living alien, right in front of their very eyes! But none of them listened. No one would listen. That didn't matter, though. I finally had something to strive for, a chance for fame and glory, acceptance. And then...then I could look down on all those who made fun, laugh at them. I would be the one on top. So I dedicated my life to proving to everyone what you really are beneath your...really God-awful disguise. Every waking moment is spend studying, pouring over notes, simple observations. All because of you. It's like some kind of unhealthy obsession or something...I've honestly dedicated my entire life to you. To you. And yet...as bad as it sounds...you've given my life purpose. You've given me a reason to continue my studies, to strive forth. To continue life, even. I..."
Dib's voice tapered off, his last climatic words wisping away into nothing. At the realization of what he just said, a horrified look crossed his voice, soon vanishing so that Zim would not laugh at him, but Zim himself had edged away a bit, totally baffled. There was a growing silence between them, Dib trying to decipher what exactly he had just said, and Zim trying to figure out if Dib was lying or not. The more Dib thought the more perplexed he became. Considering everything he'd just rambled on about, it seemed more like he should be married to the damn alien rather than the two being mortal enemies. Wasn't that a thought. Love and hate; were they all so drastically separated? Both were the deepest amount of passion that could be felt, a necessity for a flame strong enough to ignite a permanent emotion. As if directed by some other-worldly force, pulling him along in a slow, fluid motion, Dib leaned forward and pressed his lips to Zim's cheek, quickly snapping back and mentally pistol-whipping himself in the face. Zim touched a gloved hand to the spot as if it stung, and narrowed his eyes.
"What...was that?"
"Err..." Dib ransacked his brain for anything, anything that would dig him out of this hole. "It's uh, a human gesture. Of trust and, um...I guess it's like a truce."
"Hmm. Well I suppose you expect one too, then, if we are to call 'truce'." Unsure of quite what to do, Zim attempted to mimic Dib's action, with much more deliberation. Dib, of course knowing the true meaning of the gesture, nearly died of relief when he saw that the rain outside had let up.
"I-I should go now. It's stopped raining. Thanks for lettin' me stay here, Zim." With that, Dib quickly scrambled out, slamming the door shut behind him. It was at this time that Gir made his entrance again.
"Where Dib goooo?" The robot scurried about the room, looking for the recently-departed Dib.
"The rain stopped. He's gone now." Zim left it at that, touching his hand to the spot on his cheek again, eyes fixated on the door.
