This is an adaptation of a book, not an original story.
To make everything easier, here is a list of the characters in this story:

-Coral (Female Floatzel). River's sister. Belongs to Gail
-Tennyson (Male Reuniclus). Delivering stuff to his master by himself. Belongs to unnamed psychologist
-Cutter (Female Zangoose). Belongs to unnamed trainer. Teammate of Lynn and Sonya.

-Sonya (Female Slowpoke). Belongs to unnamed trainer. Teammate of Cutter and Lynn.

A few aclarations: For story-telling purposes, the protagonist is able to understand Pokémon language. I understand that it is Mary Sue-ish or borderline Mary Sue-ish, but please bear with me.
I also follow one specific point, and it is that a trainer and his/her Pokémon are able to talk and understand each other.
This story is intended to have thirty-one chapters.
-Don't you understand we have to kill her?
Any human that was around wouldn't have understood a word, but there was one exception.
Lawrence Krauthammer froze and listened. He didn't hear anything else, so he shrugged and closed the window. "Don't you understand we have to kill her" he repeated to himself. He didn't give any importance to those words, but it still was funny that everywhere he went there was something that reminded him his profession, even when he was in vacation.
He laid on his bed, and analyzed the voice he heard. It sounded nervous and contained angst and excitation. What was even more curious is that it wasn't a human voice what he heard. It had traces of being the voice of a Pokémon. He took a book and thought "It wouldn't be hard for me to recognize that voice later".
In another room, near the balcony, Coral grabbed her brother's snout with one paw, indicating the need to be silent. River nodded, and as soon as his sister released his snout he repeated, this time with a lower tone. "Don't you understand we have to kill her?"
Claire shuddered, and whispered back.
-It is horrible.
-No, it is worse than horrible.
-But we can't …
River interrupted her. – You can't live like this! Neither can our master, nor I can! We have to do something, it is the only solution.
-We could flee…-Claire muttered.
-We can't, Coral. You know it. –River's voice was full of desperation. The young female Floatzel shuddered again.
-I know, Ri, I know.
-Everyone will believe we're crazy for not leaving before.
-Maybe I'm crazy. –Coral sighed.
-Maybe, but it doesn't matter. If one said that two Floatzels are planning to kill their trainer's mother, then that person would be the one considerated crazy.
Coral looked outside the window. She didn't have anything else to say about the matter.
-Do you agree with me, Coral?
Coral nodded. –Yes, she must die. – Then Coral lost her calmed demeanor. –She is insane! I'm sure she is insane! If she weren't, she wouldn't torment everyone like she does. We believe that this can't continue. We often think "She will die shortly", yet she is still alive. I don't think she will die unless…
River finished her sentence. –Unless we kill her.
-Yes.
River approached her sister, and tried to comfort her. As indifferent as he could, he kept talking: -Do you realize that one of us has to do it? We can't count with that human Leonard and his mate, and master Gail can't help us.
-Poor master! I'm afraid about her…!
-I know. Everything is getting more complicated; we have to reach a decision before she…
Coral turned her head to the room, and watched Gail Bouyant sleeping. –So you don't think it is wrong, Ri?
-It would be like killing a rabid wild Pokémon. Bouyant is somebody that hurts everyone, and must be eliminated. She can't be stopped.
-We would be executed…we can't explain how Bouyant is; only our master understands us when we talk. And who would believe her? Everyone will think it is her imagination. – Coral muttered.
-Nobody will know – River replied –I have an idea. I have thought about it for a while. We won't be in danger.
Coral turned towards her brother.
-You're different now, Ri. You have changed. Did something happen to you?
-Why do you think that?
-Because you…tell me, Ri. Did that Zangoose you met in the train influence you?
-No way. Come on, Coral, stop the nonsense. Let's go back to…to...
-Scheming. Are you sure we can do it?
-I think so. We only need a chance. And if everything goes fine, we'll be free… Everyone will be free.
-Free? –Coral went back to the room. –Finally a chance to be normal again? Then I'm ready.
-Are you sure, Coral? If you don't… -
- No, I'll do what is necessary. For us and our master. We have to save our master!
-Then this is the plan.
River leaned towards his sister and whispered his ideas.
