As Mewtwo was dragged away by self-entitled Mewthree, its mind began to wander.
"Why... Why am I always being dragged into battles I want no part of? Why am I constantly being pitted against my fellow Pokémon? First, it was Mew and the... 'natural-born' Pokémon. Then those idiots who dared disturb my new home – hell, my first real home – with my clone brethren. Now my own 'biological' brother is taking me back... back 'home', as he put it. To fight in yet another war between humans and Pokémon. I just don't understand... why..."
Mewthree sensed its sibling's confusion and reluctance to help it, in spite of its apparent lack of resistance toward its own kidnapping, and decided to try to help it.
"Brother, I can feel you're... tense."
"It's not like I was trying to hide it."
"Please, listen to me. Together, with our other brothers, we can stop this war. Stop all wars. Forever. Other beings age and die. We do not."
"Rule the world? Is that what you're saying?"
"Not rule... We have no right to rule over what Arceus created. Just... advise."
"And when the humans don't listen to our advice and start yet another war? What then? Should we step in and enforce our will? If we have no right to rule, why should we interfere in this war? By your logic, we would be no better than them."
"We wouldn't be imposing our will; merely defending the helpless. Brother, we have the power to stop this – all of this. We would not be worthy of this power if we did not use it for the right reasons."
Mewtwo silently processed what its sibling was telling it, prompting it to point something out.
"Besides... You wanted to come home. You could have fought back. You spent weeks on that planet. You had recovered by the time those two Pokémon attacked you. Yet... you wanted them to kill you. When I arrived, it was just the excuse you needed to leave. You weren't knocked out by my attack. I barely hit you. You wanted to leave."
"That's not..."
"Please, look at what's happening on our home. Look."
Mewthree touched its sibling's forehead, transmitting flashes of what had been occurring on their planet. Mewtwo saw Pokémon turned against each other and punished if they did not obey. It saw humans being struck down by both Pokémon and other humans. Every image made it angry and sad, to the point that tears started flowing from its eyes.
"Can you feel it? Their suffering? We have the power to put an end to all of it. For good."
Mewtwo quickly removed Mewthree's hand from its forehead, before using its own psychic powers to boost their speed.
"Why-"
"If we're going to stop it, we need to get there as quickly as possible."
"...Thank you, brother."
