"Change of Heart"

Regret

The four of you made to Bulma's within seconds. Goku took you inside where everyone was talking. "Alright! (Y/N)'s safe. They didn't kill her or anything." You muttered under your breath, "I still don't think it was Zamasu..." The older Trunks spoke, "What are we going to do about them?" After a few moments, Piccolo said something. "What about the Evil Containment Wave?" Goku responded, "Oh, yeah! I almost forgot about that!" Bulma added in, "That's a great idea! Why didn't we think of this before?!" Vegeta turned to Bulma, "How soon can we leave?" "About 12 hours." "Alright..." He walked to the door while Piccolo spoke to him, "You going back to the Hyperbolic Time Chamber?" He responded, "Of course... Maybe we'll seal them, but not until I've given them my own brand of punishment..." With that, he left the room.

"The Evil Containment Wave... How do I do that again exactly?" Piccolo stood up while Krillin spoke, "Master Roshi can show you, right?" "Oh yeah!" Piccolo spoke, "I'll gladly show you myself." Goku stood up with his fingers on his forehead, "Nah, that's cool. Rossi's the expert, right? See ya." After that he disappeared, leaving everyone silent. "Well, Piccolo, you can still show us if you want." You just sat there in silence. You really didn't want to be here right now, you just wanted to go home.

Zamasu was being very resistant whenever he was given orders. Black put visions through Zamasu's head if he resisted. The visions were usually of you being killed in front of him and he can't do anything to save you. And Black would always remind him this will actually happen. The sound of you screaming his name and the horror on your face has been burned in his memory. It always felt so real. It made Zamasu want to kill Black even more.

Speaking of Black, he hasn't seen him for a while now. Earlier he flew off without a word and hasn't heard from him since. He probably went off to kill more mortals. Zamasu could just run off right now if he wanted to. But he can't go back to the past. He doesn't have the same ability as Black. And if Zamasu did run, he'll be bought back and you'll suffer. Maybe that's a risk he's willing to take. Zamasu remembered the time ring he took before leaving his timeline. He took it out of his pocket and slipped it on. He was about to leave until Black appeared in front of him. Zamasu quickly threw his hand behind his back so Black couldn't see the ring. Zamasu looked at Black and noticed the person on his shoulder. His heart dropped as he recognized it was you. He stood up, "What the hell are you doing?! I thought you wouldn't do anything to her!" "I didn't do anything, I just bought her here for some... Motivation for you..." Zamasu noticed a bruise on your face, "What's that on her face then?!" He grabbed Black's shirt, "What did you do to her?!?!" He pushed Zamasu off, "You know better than to do that!" As he got up, Black spoke as he held his hand up to your head and a ball of ki appeared, "You must really want me to kill her." "No! I'll... I'm sorry..."

Emotions were just swirling around in Zamasu.
Anger, Fear, and Guilt. He was playing with your life from the decisions he made. Gowasu was killed because of him. Now he's at the mercy of this mortal. He destroyed his whole life and you're going to hate him. You're his princess and he'll do anything in his power to keep you safe and happy. Maybe even spend the rest of his life with you.

But he can't. Those chances are gone.

You didn't deserve this.

Black lowered his hand and opened the door, "I'll be right back..." He walked in the cabin and closed the door. When, or if, you wake up, you'll be panicking. You'll be scared and alone and there was nothing Zamasu can do to comfort you.

You stood on the deck and just looked at the sky. Your elbows were on the railing and your hands held your head up. There weren't many stars in the sky because of the light pollution. Right now, you were just thinking. It was quiet and there was a gentle, warm breeze. Usually, you'd enjoy nights like this. Especially with Zamasu. Tears rolled down your cheeks when you closed your eyes. No matter how much they tell you, you don't believe he would do something like killing Gowasu and millions of others. He made a promise too. Maybe he's not what he seems. You want to see all this for yourself to see if everything is true. Maybe you could try to get through to Zamasu and get him to stop. You're one of the only people that's not afraid of him and you know nothing about fighting.

You've made up your mind. You're going to talk to Bulma about going to Trunks' timeline when they leave. When you turned around, you bumped into someone. You looked up at them, "Oh, sorry. I didn't see you there." The person was Goku, but he was in a different outfit. He was wearing all dark colors. "Goku? What are you doing here? I thought you went to..." Then it hit you. This wasn't Goku. It was Black. Before you could react, his hand went over your mouth. You struggled while screaming, but I one could hear or see you. Black's grip was strong. He went to your level with a smirk, "Shshshshshshhh... Calm down, dear. I won't hurt you..." You stopped and just looked at him. "I'm guessing you're worried about your precious Zamasu? Don't worry, he's safe..." Something took over and you bit his hand. He reacted immediately and punched your cheek with the palm of his hand, which knocked you out cold. "You little bitch..."  He picked you up and threw you over his shoulder. Then he teleported to his timeline with you.
