One day had passed since the attack. Giovanni explained what Team Midnight stole from his organization, Team Rocket. The thieves had taken research on cloning and gene-splicing, along with a lot of equipment related to that research.
Even though Giovanni and Team Rocket had similar objectives to Ash, Professor Oak and the other heroes, tensions and distrust was still high. Professor Krane, viewing Team Rocket as no different from Cipher, said they were not allowed anywhere inside the lab. Period. Also, he sternly warned them that if he even caught a glimpse of any member of Team Rocket, including Giovanni himself, trying to set foot inside, or even near the door that he would sick his Aggron on them without hesitation.
Giovanni wasn't greatly intimidated by Krane's threat. But he complied with Krane's condition, to keep the peace between both parties. He knew having more allies than enemies would be beneficial in the long run.
At the time, Ash, Misty, Brock, Tyler, Michael, and all the Professors were rebuilding the lab with aid from their Pokemon and the Balancers. All of Team Rocket was standing guard and had set up a perimeter around the entrance to the lab to make Team Midnight think twice about attacking again.
Mewtwo and Mew watched from a tree, observing Team Rocket's patrols. Mewtwo knew this wasn't going to be easy. If Giovanni caught sight of him or the others, he feared what he would do.
Mewtwo turned to Mew and Celebi. "Any ideas?" He asked.
Celebi then flew down from the tree branch he was perched on. Both Celebi and Mew brainstormed up several plans that might let them get to the "altered ones," but only one had the best shot at success.
One of them would have to sneak into the facility from the back, most likely through an air vent. Then, they would have to convince the "altered ones" to come with them outside, where the rest of the group would be waiting. This meant that it would either have to be Celebi or Mew's job to sneak in. Mewtwo would most likely make a lot of noise going through the vents due to his size. Also, none of the Legendary Beasts would be able to fit in the air vents, anyway.
Mew immediately volunteered. Celebi showed concern, but Mew reassured it, saying that the only human that had caught a glimpse of him was Ash Ketchum, and that he though he was just seeing things.
"Good luck, Mew." Mewtwo said. "We will be waiting for your return."
Mew nodded and set off on his task.
