(Back with Lard Nar…)

This was it!

They had arrived on Earth's Moon…

Lard Nar allowed a sigh of relief as they landed on the moon. "We've made it." He said, his voice was but a whisper. However, no one missed his words.

"Wow." Queen Luna gasped as she look out her window. There was a perfect view of the Earth on her side, and she just couldn't believe how beautiful it was. She had almost forgotten how breathing taking a planet full of life could be. "Moon look at this!" She insisted to her younger sister.

Moon rushes over to her sister's side and takes a peak, and gasped. "It looks like home!" Moon exclaimed.

And at first glance it did resemble the Magladies home world, however Earth was more liquid than land, which was the complete opposite of their home world. Still with a little imagination Queen Luna could see herself and Moon returning home.

There were tears in Annabel's eyes as she took in the sight. "Dad." She whispered.

"I know." He said. "It's beautiful."

Both of their hearts beat rapidly as they imagined lading and walking up to the Membrane home and seeing the tears on their love ones faces. Tears of joy because they were all together once again.

"So, this is Earth?" Jinx asked. "No wonder the AI's are so protective of it." He said in awe. "I can't think of any life form that couldn't live here."

"Yes well hopefully The Earth Authorities will be willing." Lard Nar said. He then turned to Richard. "This is your home how do you want to proceed?"

Richard looked to Annabel, and she nodded. Finally, he spoke. "I think it best if we go down first in the shuttle and let Dark Booty know we are here."

"Lard Nar should come with us." Annabel cut in. "Dark Booty might need…proof."

"Then we'll take Sari as well." Lard Nar added.

"But won't she kill Zim on sight?" Richard asked.

"No." Lard Nar said. "The other's Maybe, but Sari, I believe if she detects Zim, she'll respond… better."

"Good enough for me." Annabel agreed. "Besides, she will insist that one of them goes with us. There is still a missing piece of the weapon."

"Speaking of it's important that we convince them that the pieces are safest within the Swollen Eyeball." Richard added.

"Sari and the others will not like having the pieces out of reach." Annabel stated the obvious. "But if one of them could stay within the Swollen Eyeball to guard them I think they'll be more willing."

"Then it's settled." Lard Nar said. "Let's suit up and address Sari in the cargo bay." He ordered. "Queen Luna will you please inform the refugees that the rest of you will be staying here for a few days. Also moon walks are only allowed for short periods at a time, and not too far from the ship."

Queen Luna nodded and stood to address her people, "Be safe Annie." She told Annabel.

"We'll miss you." Moon said giving her a big hug.

Annabel hugged her back. "I'll be back in a few days." She promised. "Hopefully with good news." She added.

Moon nodded and reluctantly let go.

"Let's do this." Annabel said.

Her father and Lard Nar nodded and took their leave, they headed out of the passenger area and towards the back of the ship were some space suits were stored. There was also two doors, the one to the left lead down to the cargo bay; and the one to the right lead to the shuttle.

Annabel dawned her space suit and headed for the Cargo bay. "I'll let Sari know were leaving." She stated.

"You know sometimes I think she like them more than us." Lard Nar joked.

Richard laughed. "She does." He seemed to agree. "And who could blame her I mean look at us."

Lard Nar laughed as he finished putting his own suit on and headed for the shuttle. "Well here goes nothing."

"Nothing but luck." Richard added as he followed his old friend into the shuttle. Meanwhile Annabel had entered the Cargo bay where she was greeted by Klem.

"Annabel I trust we arrived with little to no complication." He said.

Annabel nodded. "Everything is fine, Lard Nar simply request that Sari joins us."

Sari stepped forward looking alarmed. "My sensors tell me there are two nearby."

Annabel bit her lip but nodded. "We were just informed that there are indeed two Irkens on the planet's surface."

She waited for the AI's to become angry with her, however she got a very different response.

"The two must be competing for the planet." Titan said.

"Competing?" Annabel asked.

"Often an Invader will challenge another for their chosen planet to invade." Melk explained.

"With any luck they'll be too busy with each other to notice our arrival." Tuff added.

Annabel's eyes lit up. "So, this is a good thing!' She exclaimed.

"Is it HE!" Sue asked suddenly.

Annabel grew nervous again but nodded. "Yes it's been confirmed, Zim is one of the Irkens here."

"You must eliminate him." Sue said to Sari.

Annabel moved to object, but Sari was quick to speak for herself.

"We are not Irk!" She said to Sue in a way that resembled a mother lecturing her child. "We do not kill aimlessly."

"Than what will you do?" Annabel asked.

"I will connect with the Zim's PAK." Sari revealed catching her fellow AI's by surprise. "I will look within and then based on what I see I will decide his fate."

"Why show HIM mercy!" Sue demanded to know.

"Because." Sari answered simply. "To defeat Irk we need Irk."

Annabel wasn't sure she understood what the AI meant by this, but Titan seemed to understand.

"If we perform genocide than we are no better than our creators." He stood by Sari proudly.

It is than that Annabel understands.

Sari didn't want to destroy the Irken race for fear of becoming monsters themselves. However, she knows that she cannot save Irk, only an Irken could.

To defeat Irk we need Irk

Yes, it was simply the means of fighting fire with fire, but could they convince Zim to betray his entire race for the common good?

"Lard Nar tried to convince Zim once." Annabel revealed. "It did not go well."

"With age comes Wisdom." Titan assured her.

"His programing confuses him." Sari agreed. "I will relieve him of that confusion."

"Then it is settled." Sue said, still sounding unpleased with the decision, but the power couple Sari and Titan had spoken, and no one ever challenged them.

"I will meet you on Earth's surface." Sari said.

Annabel bit her lip once more.

"There is more?" Melk asked.

"Lard Nar thinks it is best to put the pieces of the weapon in the safety of the Swollen Eyeball." Annabel revealed.

Silence…

It lasted for a moment than Titan answered.

"If this is to be…than I will guard them." It was not a suggestion, but a statement of fact.

"Agreed." Annabel approved. "They can stay here for now, but we'll be taking them and you when we get back."

Titan nodded. "Trust you, we do." He told her. "Trust is hard to gain."

"And easy to lose." Annabel finished. "I know, and I will not let anything bad happen to it."

"This weapon is a last resort." Sari said. "If we cannot convince Irk to change than for the greater good we must eliminate them."

"So, it's all up to Zim." Annabel asked. "That's a lot to put on one guy's shoulders don't you think."

"It must be Zim." Sari said, it would appear she was the only one brave enough to say his name. "He is the only one."

"What does that mean?" Annabel asked.

"Only one can change Irk's fate." Titan said, "And he was chosen."

"Chosen?" Annabel asked. "By whom?"

"It will make sense in time." Sari assured her. "Now I will meet you at the surface."

Annabel nodded, deciding that she wasn't going to get more information for now. Still, she could tell that something had change about the AI's. Before they left Zoran they were determined to purge all of Irk, but now they were willing to give them a chance.

But why?

What did they know that the rest of them didn't?

She wasn't sure, but maybe Lard Nar could shed some light on the subject. "See you there." She assured her and then made her way to the shuttle bay.

"We told her too little." Sue said.

"No, we told her too much." Klem argued.

"No, we told her enough." Titan assured them. "Sari you know what to do."

"Consider it done." Sari assured them and with that she left the cargo bay to start her own journey to Earth's surface.

Meanwhile, Annabel had arrived in the shuttle and was taking her seat.

"What's the word?" Lard Nar asked.

"Sari will meet us on the surface." Annabel answered looking worried.

"What's wrong?" Richard asked.

"Somethings changed." Annabel said. "They said something weird."

"What did they say?" Lard Nar asked.

"I told them Zim was here." Annabel admitted. "And Sari and Titan said they would judge him."

"Judge him?" Richard asked.

Annabel nodded. "They said, 'His programing confuses him' and Sari will 'relieve him of that confusion.'"

Lard Nar's eyes seemed to widen. "Did they say why?"

"They said he was chosen to change Irk's fate." Annabel revealed.

Lard Nar suddenly smiled at her words. "This is good." He assured her.

"But what does it mean?" Richard asked.

"The AI's must still be connect to the other brains on Irk to know that Zim was chosen." Lard Nar answered.

"Yes, but chosen for what?" Annabel demanded.

"I told you." Lard Nar said. "There is only one way to change Irk, the next Tallest has to challenge their leaders."

And that's when it hit her like a brick wall.

Irk's fate was up to Zim because Zim was to be the Taller of Irk!

However, Lard Nar knew that it wasn't that simple, a total of three would be chosen as possible Candidates of the role. Still, the AI's must be pretty confident in Zim's chances why else would they change their mind.

What they do not know is it is Zim's presents that has changed everything, if it had been another Irken on Earth Sari might have agreed to eliminate them and be done with it. But Zim was special, Zim was family.

Sari shifts into a spear as she lunches herself from the moon and towards the planet ahead. "I am coming Brother." She spoke in the Irken tongue. However, the chances of Zim hearing it were slim to none.

And yet, it didn't not change the truth, Judgement Day was coming whether Zim was ready or not!
