Dib was looking at the tired looking invader with confusion. His own people didn't know he was a scientist, not to mention the head scientist? He had only tried to conquer the world once? He knew Dib was a genius? "Um… what the heck?"
"I do apologize for the ruse, Dib, but I feared that they might check up on me, and if they saw us getting along, then they might have just destroyed this planet with no thought whatsoever." Zim explained calmly as he sat on the couch.
"Zim, honey?" It was the mom-bot. Dib was surprised to see it acting like an actual mother at the moment. "Was that the Tallest?"
"Yes, Mother." Zim nodded as the bot came around the corner. "Don't worry, they just wanted to finally tell me I'm banished. I have to call up Tak later so I can help her get her ship repaired and get her off this planet. She's not really happy here, after all."
"Oh, don't worry so much dear. You'll figure it out." She smiled kindly. "Oh, hello, Dib. Would you kids like some cookies?"
"That would be nice, Mother. Would you like some, Dib?" Zim asked as though he had been friends with the boy for years.
Dib simply nodded as he tried to take everything in. "I really am crazy, aren't I?" The poor teen sighed as he sat on the couch in a slump.
Zim shook his head. "No, Dib, you're fine. I on the other hand might be a little… insane… but eh, that's what happens when you grow up in a lab and your best friend is a malfunctioning robot, eh Gir?"
Gir gave off a giggle from the kitchen before arriving with a tray of decently cooked tacos and a bottle of medicine, along with two cups of milk. "YEP! I made tacos! OH, and I brought your medicine, Master."
"The Tallest are gone now, Gir, you don't have to call me that anymore." Zim smiled as he gratefully took the medicine bottle, opened it up, and ingested two pills before eating some of the tacos, much to Dib's surprise.
"YEAH! I can call you my bestest friend again?" Gir looked up pleadingly. Zim smiled and rubbed the tiny robot's head.
"Yes, you can. Thanks by the way, these tacos are a lot better than last time. What did you do?"
"I added SALSA!" Gir exclaimed as he put the tray down in front of the two boys.
Zim nodded. Dib on the other hand was still confused. "Aren't you allergic?"
Zim looked at him and then back to the tacos before laughing. "Not really, so long as I take some medicine once a day, I can eat meat and even interact with water." That was a surprise to Dib. That knocked out the majority of his ideas to destroy Zim and any Irken threats. "Relax, as I stated, I'm not even interested in taking over. If anything, I really like this place now and want to protect it as much as you do. Seriously though, some of these humans are so dumb!" He laughed. "I mean, I only needed contacts and a wig and they thought I was one of them with a skin condition? How gullible?" He started laughing, and Dib, much to his own surprise, started to laugh as well.
"Yeah, hahaha, oh man, but why keep me believing that? I mean, I get when the tallest asked for reports, and heck, I even understand with Tak, but why not try to make peace with me?"
Zim looked a little down at this. "Because, I was worried that if you knew that I was a scientist you would treat me like they did on Irk, like I wasn't capable of anything but being in a lab and thinking. I can plan, I can fight, I can do so much more than just sit behind glass and watch as things happen…" Then he looked up at Dib. "You should know that I admire you. You put up with all the insanity that I put you through, you put up with the hatred from everyone because of me, and yet here we are, years later, after we've both calmed down from the initial 'Alien Invasion' thing, and… well…"
"Now we're friends…" Dib held out his hand, hoping that Zim would agree to this. The alien was right, even when everyone else treated him like he was insane, the two had grown to respect each other on their own way.
Zim smiled and nodded. "Yes, now we are friends…"
