Mr. Fuji's information led her to a cave just outside of Cerulean city. To find Mewtwo so close to a city was surprising. But once inside the cave, the reason for that became much clearer. The cave was a difficult maze of passages winding up and down on top of each other like snakes in the dark. Luckily, or unfortunately, Spamira wasn't a stranger any more to stumbling around caves and dealing with the occaisonal tripping hazard and skinned knee. At least until she just had Noriko start to clear the path where ever possible. Hundreds of pounds of steel armor and muscle were useful for that.
Before she ever saw Mewtwo, she knew when she reached the level it was on. The stillness in the air felt forced, as though by some will someone wanted to maintain a silence. Setting foot in the cave felt like an intrusion that had been immediately noticed, which only made the silence all the more unsettling. Nervous questions began echoing in her head. Could she do this? She remembered the burned, half-collapsed building in Cinnibar that Mewtwo had destroyed in the process of escaping, and would she be able to fight something like that?
Yet with all that concern, she nearly missed Mewtwo when she finally saw it. It was sitting curled and hovering just off the ground, head leaning against its knees, tail wrapped around its body. Being so still with its grey coloring made it look much like another rock or stalagmite. But even with it being so still, she still had the feeling that she'd been under constant watch since she had stepped into the cave.
Mewtwo's aboslute stillness confused Spamira the most. She had no idea how to respond to a Pokemon that showed no reaction to her presence. "Uh... Are you asleep?" she asked, not realizing until it was over how quietly she'd spoken. "Do I need to get the flute out? I've still got it since I had to wake up Brian and get him to- AH!"
She was cut off as a force suddenly knocked her feet out from hunder her, making her fall forward, barely catching herself with her hands. But she couldn't even get onto her feet again before something began jerking her bag away from her. She could see out of the corner of her eye that Mewtwo was uncurling itself and stretching out without touching the ground still, but all Spamira could focus on now was trying to keep her bag from getting ripped away. Or, failing that...
"Stop that! I'm not here to... Ugh!" She reached blindly into the bag and grabbed at the first Pokeball that she touched. She didn't even look at it, instead trusting the leaf decoration engraved on the top half and throwing the ball out between her and Mewtwo. "Kazumi! Help!"
Kazumi barely touched the ground before she vanished in a flash of speed, appearing again only in a flash of her fans in front of Mewtwo's face, distracting it from the follow up hit and breaking its concentration just enough for Spamira to be able to grab her bag again, already reaching for another ball. She froze as she saw Kazumi be blasted with the kind of psychic wave she could normally shrug off, but from Mewtwo blew her off her feet.
"Noriko!" Spamira yelled, readying to throw another Pokeball, but instead dropping it as a much stronger wave of force threw her back, slamming her between two stalagmite columns against the wall. Before she could work free, a stalactite snapped off of the ceiling and slammed against the columns, making a bar that Spamira couldn't push away, leaving her trapped, and only able to watch in horror as Mewtwo opened each remaining Pokeball one at a time.
Noriko only had a moment to stand before her weight was turned against her, forcing her down onto her stomach while the weight of Mewtwo's malice made the cave floor crack around her.
Ambrose's Surf was deflected and bounced back into a bubble that wrapped around him, leaving him floating off the cave floor and unable to work himself free.
Ringo tried to match Mewtwo in a psychic battle, but that only seemed to make Mewtwo angrier, and the only result of their mental struggle was for Ringo to clatter to the ground, unconscious.
Belinda was knocked onto her back and left unable to right herself again. Every time she tried to roll to the side she'd be caught against some invisible object, rolling her onto her back again.
But her horror only really set in when she saw the last Pokeball and realized how terrible a mistake she'd made. An expression of amusement finally crossed Mewtwo's face as the ball cracked open and deposited Cassidee on the cave floor. Cass didn't look afraid, even while Spamira doubled her efforts to get free. "Don't! Don't you hurt her! Don't you even touch her!
: ...Why are you doing this?
: Why am I doing this? Why would you try to to protect a human?
: She's our friend!
o: Friend? Is that how you try to justify being used by a human just using you for-
: You know that's not true!
: ...What did you say?
: You're psychic right? You could tell what we're thinking right? Just like Mister Ringo knows when I try to take two lemonades.
: S-so you should know that she just wants to help Pokemon! You're just scared!
: Like I was scared when I met Spamira. I was scared of humans... I thought that they all had to be bad... When she let me out the first time I tried to hit her. But she was just wanted to hug me. A-and it's because of her that I got to make so many friends.
: And I was scared because there were so many bad humans, but there's more good ones than bad ones. ...I'm sorry you didn't meet any before... But you don't have to be angry. I remember I was lonely before I met Spamira and made friends with the others. We could be friends!
Every moment that Mewtwo wasn't attacking Cassidee yet was another moment that Spamira could try to wiggle her way free. But she couldn't get the pillar off from barring her in to the crevice she'd been pressed into. Luckily, she didn't have to.
Maybe it was Mewtwo's distraction, or maybe Ambrose just put too much pressure on the bubble he was trapped in, but it suddenly burst, dropping a torrent of water of water that rushed out over the cave floor. Ambrose wasted no time in rolling onto his flippers again to blast another jet of water at Mewtwo. For Mewtwo to divert it seemed effortless, but that gave Noriko the chance to get to her feet, putting her strength into freeing Spamira.
"Cassidee!" Spamira screamed and hit the ground running, looking straight ahead. She dove onto her knees to throw her arms around Cassidee to pull her away. Mewtwo whirled around to face them, eyes blazing with malice and with one hand pulled back and glowing with energy. There was no time to run, only time to do one thing:
Shield Cassidee from Mewtwo and wait.
For a while she thought that the only thing she could hear was the sound of her pulse as she waited for something to hurt. But nothing came. It wasn't until Cassidee began squirming that Spamira dared to look over her shoulder, although she didn't let Cassidee go yet.
Mewtwo was still poised to strike, but the malice in its gaze replaced with puzzlement. It stared at them as though the most bizarre thing it had ever seen was a human putting themselves in harm's way to protect their Pokemon. Slowly its hand lowered, although Spamira was still too frozen to move. It was Cassidee who finally wiggled free to step towards Mewtwo, holding up one of her hands.
Spamira nearly screamed and pulled Cassidee back when Mewtwo reached down, but the fragile sense of peace restrained her. Mewtwo took Cassidee's hand, showing the barest of smiles. Then it stepped back, lifted off the ground, and in two quick flashes vanished from the cave.
Spamria still didn't move, not until enough time had passed that Ambrose felt safe shuffling over and nudging against his trainer, who promptly fell on her back to stare at the ceiling in exhaustion. "That's it," she said, reaching up to pat Cassidee's head. "We're going to go on a vacation and there's gonna be no gyms or criminals or dangerous super Pokemon.
"And if Mom asks, we went to the library today."
