A few years went by and Cynder was old enough to be trained by her brother, and taught the Zero Mortal Plan. She of course didn't understand why they had to kill the people, because she would sneak out at night and look around in the city, and use the spare time ring to travel into the past to meet the people.

Cynder: Explain again to me why we have to kill the people?

Black: Because they are disgusting and pollute this planet.

Cynder: Yeah well, humans aren't perfect. I mean some are good, some bad, there is even some that are in between.

Black: You went time traveling again, didn't you?

Cynder: How did you know?

Black: Because you're still wearing the time ring. But you may keep it. It's yours anyway. I created it for you. But remember, use it wisely.

Cynder: For what? Killing mortals in all of the timelines?

Black: That's not a bad idea. You're catching on, sister.

Cynder: I was being sarcastic.

Black: Well in that case, go clean your room. You didn't believe me when I said I'd make you do it. Now go do it.

Cynder: But why should I?

Black: Because it is a mess. And you have a doctor's appointment tomorrow.

Cynder: Do I have to go?

Black: If you want to continue to stay healthy, yes. Or I could just cancel it and let you get sick.

Cynder: Fine, I'll go....

Black: Good girl. Now go clean your room. I'll reward you if you do.

Cynder: What will you reward me with?

Black: A full day's training with me.

Cynder: Can't we do something fun?

Black: Like what?

Cynder: Like going to the park or visiting Grandpa Gowasu.

Black: Fine. Hurry up and clean your room and we'll go.

Cynder: Yay! *Cleans her room quickly*

Black: You done already?

Cynder: Yes, now let's go!

Black: Fine...*takes her to the park*

Cynder: Come on, push me on the swings! *Sits on a swing*

Black: Hehehe, alright. *Gives her a strong push* There you go.

Cynder: Wee! This is fun! *Does a loop around the top pole* *jumps out and lands perfectly*

Black: That's my sister. Now can we go? I'm tempted to kill everyone here.

Cynder: Okay, fine. *Sighs*

Black: *teleports them home*

Cynder: Hey Zamasu, we're home!

Zamasu: Already? That was a short trip.

Black: I was very close to killing those mortals in the park.

Cynder: And ruining my fun.

Black: Look, I'll make it up to you. I promise.

Cynder: You'd better.

Black: But for now, just get ready for your doctor's appointment for tomorrow. I want you to wear something decent. Not your play clothes.

Cynder: But I'm comfortable in them. Why do I have to wear something else?

Black: Because your play clothes are filthy and need washed. Now pick something else to wear and I'll wash your play clothes for you tonight. And get ready for bed.

Cynder: Fine. *Goes to her room* *puts her pajamas on* *sets out her skirt type gi*

Black: Very good. Now put your dirty clothes in the washer and I'll get them washed tonight.

Cynder: Okay. *puts her dirty clothes in the washer*

Black: Now, go brush your teeth and go to bed.

Cynder: Fine. *does as told*

Black: Goodnight, sister. I love you.

Cynder: Love you too, big brother. Goodnight. *Goes to sleep*

Black: *tucks her in and shuts off the light* *leaves*
