Later, Bulla flew over to the castle before she then went over to a window and saw Broly shaking as if he was about to lose control again. Then, Bulla went over to Broly and spoke to him.
"It's okay. I'm not here to fight you. I just want to talk.", Bulla assured, caressing his arms enough to calm Broly down.
"See? There you go.", Bulla responded.
"I thank you very much. I am grateful.", Broly thanked.
"You don't have to be so formal. Just saying 'thank you' is enough.", Bulla responded, slightly stunting Broly before he spoke to her.
"I thank you.", Broly responded.
"Eh, close enough.", Bulla grinned before then realizing something she wanted to ask.
"Oh. So, uh, about Goku. Why do you hate him so much?", Bulla asked curiously before Broly growled at the mention of his earth name before calming himself, remembering that she's here and gesturing to his red sash.
"This is…Cauly's sash.", Broly responded.
"Cauly? Who's that?", Bulla asked.
"My late sister. Me and Cauly got along well back then. Back when Planet Vegeta was still here. Cauly may've been my twin sister, but her fearsome power nearly equals mine. She was scary when she got mad. But I got over that. And I even started to train with her, even if we do get overboard sometime. For siblings, we were almost like friends.", Broly responded, thinking back on his pleasant memories with his sister back on Planet Vegeta, even smiling.
"Aw. So, you actually had fun with your sister, even if you both go overboard sometimes?", Bulla asked.
"Yeah, but your grandfather didn't like that one bit. He said that one day, our powers may get too strong and take over us. So, then…", Broly began before it showed a flashback of King Vegeta speaking to his subjects.
"No more discussion! I want the children executed immediately!", King Vegeta announced before noticing Paragus stepping in.
"That's far enough.", one of the staff spoke to the guards.
"Ah. Paragus. I didn't call for you.", King Vegeta spoke.
Then, Paragus began to plead as the guards began holding him back.
"Sire, have mercy on him. He could be of great help to Prince Vegeta and our planet! Please, he's just a child! The data could be wrong! He could grow up to be a great warrior!", Paragus pleaded.
"That's exactly what I'm worried about. The truth of the matter is that your children, Broly and Cauly's latent abilities have abnormally elevated. I'd even go so far as to call them freaks. Someday, that power of theirs will drive them completely insane. When the time comes, they'll be a danger not just to Planet Vegeta, but to the entire universe. And that's a risk I can't afford to take.", King Vegeta spoke to Paragus.
"But sire…!", Paragus began.
"And I don't like arguments! You'll die with them!", King Vegeta shouted before preparing his Orca Blaster and firing it at Paragus in point blank range, knocking him back before then showing someone walking in toward the nursery where Paragus' wife, Okara, and her daughter Cauly were there as Goku, or rather, Kakarot as he was called back then, was crying when someone walked in and then proceeded to kill Cauly and Okara with no hesitation, much to Broly's horror before he tried to call for help, only for those cries to be drowned out by Kakarot's crying as the man then claimed Cauly and Okara's lives as they gave dying screams, which hit Broly where it hurt the most as he gasped, shock completely overtaking him before he was grabbed with the same man who raised his sword, but not before the young boy could run to Cauly, grieving for her as he sobbed, holding onto her red sash tightly, even after getting picked up as Broly spoke again.
"King Vegeta ordered his men to get rid of us in any way they can. When that man burst into the nursery, I tried to call for help, but Kakarot's cries drowned them out. By the time I could even get help I was too late. That man killed my mom. And…Cauly. After that, I was never the same again…", Broly narrated as it transpired before sometime later, all four were now dead (or at least half of the 4) as while they were in a space pod of their own, the other 2, Broly and Paragus were now inside another space pod next to it.
"They're all taken care of, Lord Vegeta. What do we do with the bodies now?", the guard asked.
"Send them to Planet Vampa.", King Vegeta ordered.
"What? But sire, isn't that planet inhospitable?", the guard asked.
"Well, it's better than just tossing them in the trash, even if they did deserve it. Besides, in the event that they are alive, Exile is the harshest punishment I can give to them. And if they are, they should be grateful I'm sending them to an off-world planet and not merely ending their lives.", King Vegeta responded.
"Oh. Uh, as you wish, sir.", the guard spoke before the two pods were then sent to Planet Vampa.
Broly then continued as it then showed a younger version of him and Paragus arriving first while another ship landed elsewhere nearby before it opened up with broly waking up to see the red sash he was holding on to, reminding him of Cauly before he ran out to look for her while Paragus regained consciousness and grew angry, even to the point of vowing revenge, while Broly ran over to the dead bodies of Cauly and Okara, which saddened him greatly before he hugged Okara one last time, sobbing softly.
"Some time after, I woke up in a strange planet called Vampa. After that, I went out and saw the other space pod nearby and knew that they had to be nearby. And they were here, but they still didn't make it. Some time after our exile here, help came for us and got us out of Vampa. And that's how we got here. And through it all, I keep this sash to remind me of the time when Cauly was still here.", Broly responded as it then flashed back to the present.
"Oh, no… Poor Broly…", Bulla spoke, not knowing that Paragus was on his way to check on Broly, only to open the door slightly and see, much to his shock, Bulla speaking with his son here of all places, but dared not open it any further.
"I'm really sorry you had to go through all that. I understand if you don't want me around. I'm not sure I want to be here, either. Not if it causes you that much pain…", Bulla spoke.
"Actually, I don't hate you.", Broly responded.
"What? You don't? But…, you know who I am, don't you? Bulla? Vegeta's daughter?", Bulla asked.
"Believe it or not, I don't hate you or him. And in spite of what King Vegeta tried to do, I don't hold that against him. At least, not anymore.", Broly responded.
"Because you realized it might actually be the truth when you lost control at some point, whether he realized it back then or not, right?", Bulla guessed before Broly nodded.
"Oh. Anyway, about Goku, he was very young back then. I'm sure he didn't mean it. And if he found out why you hated him so much, well… I'm sure he'd feel bad about it, too. If anything, he'll even come up with a way to bring back your mother and sister.", Bulla responded, surprising Broly, making him gasp.
"What? Can it really be done?", Broly asked.
"Yeah. All you have to do is gather all 7 dragon balls, summon the dragon and tell him your wish. From there, he'll grant it and they'll be as good as alive again.", Bulla grinned, surprising Paragus as he gasped softly.
"Can it really be done?", Broly asked before Bulla nodded.
"We even have our own set of dragon balls back on Earth that can make sure of that, too.", Bulla added, making Broly shed tears of joy as one even dripped on the red sash.
"But as for Goku, I'm sure he'll lend a helping hand for that, too. If you'll let him.", Bulla responded before Broly sighed a bit in response.
"All right. I suppose I'll… give him a chance.", Broly responded, making Bulla grin.
"As for your father, though, you don't even like what he was doing to you, do you?", Bulla asked, thinking back on when Broly had to be reined in to prevent him from going too far.
"If I had to guess, I'd say after seeing your potential, he tried to make a weapon of vengeance out of you, against your own will, too. For all I know, your father may as well be using you just to get his revenge. That's a really awful thing to do. And I'm sure Okara and Cauly would agree if they were still here. You know, you don't have to do everything he tell s you to do. I know I sure don't.", Bulla responded, peeving Paragus a bit as he growled.
Broly, on the other hand, responded calmly.
"It's not right for you to say those things about him. He's my dad.", Broly responded, making Bulla worried for him as she sighed.
Then, Paragus sighed sadly a bit and thought to himself.
"I'm sorry, Broly. But I'm doing this for us.", Paragus thought before realizing something about him today.
"Wait a minute. Last time I saw him, it looks like something got to him. Or someone. How was she able to calm him down like that? I could barely control him in front of Kakarot. Wait a second. Could that really be it?", Paragus thought before realizing something.
"He was there the day it happened!", Paragus realized, thinking back on a few memories of when a man burst into the nursery to do his job and growled angrily from the thought.
"Fate may have brought them to this planet together, but it won't be for long. At least, it better not be. Just a bit more time… If Bulla can just manage to keep him calm if I can't control him until then…, all our troubles will be over.", Paragus thought.
Meanwhile, Goku watched form the crystal ball in the Land of the Kai's as it showed Broly and Bulla.
"Wow. Broly went through all that trouble because of me…?", Goku spoke in shock.
"Apparently. I had no idea what he went through myself.", Kibito responded.
"Well, I'm good to go, guys. Whenever you're ready.", Goky grinned.
"What do you mean 'good to go'?", Kibito asked.
"I mean I'm ready for you guys to drop me off on New Planet Vegeta. I wanna make it up to Broly.", Goku responded.
"Forget it! You couldn't defeat Broly in your present condition! Not only does he have enough power to manhandle even your Super Saiyan 3 form at his disposal, he also has more than enough potential energy to transform into his latest transformation beyond Super Saiyan itself, which could control him completely if it was unleashed! Even if he wasn't the bad guy we thought he was, we're talking about a being of immeasurable power! And you're not even capable of sustaining Super Saiyan 3 anymore, especially since Broly proved that form unnecessary the moment he overpowered you in his normal Super Saiyan state alone. If you fight him now, you'll die. Just as you would have if Gohan, Goten, Pan and Trunks hadn't come to your rescue.", Elder Kai discouraged.
"Who said I was gonna fight him this time? I'll just explain to him that I didn't mean for any of that to happen and I plan on bringing his mother and sister back with the dragon balls. Whatever the case, I can't just stand around and let him lose control and destroy the universe.", Goku responded before Kibito stopped him.
"Now, who said anything about standing around? In case things go south, we're going to train you, Goku.", Kibito assured.
"What? Really? Awesome! Training with the two of you in the Sacred Land of the Kai's?! This is like a dream come true! Well, let's get right to it, then! I hope we don't wreck your planet too bad.", Goku grinned before Elder Kai chuckled a bit nervously.
"Actually, you won't be training alone. In fact, I have a couple people in mind, and I have a feeling you're already well-acquainted with them.", Elder Kai responded.
"Really?", Goku spoke in slight surprise.
Meanwhile, Trunks, Pan, and Giru turned to each other as the coast was clear.
"Paragus up to no good. Giru. Giru.", Giru responded.
"I knew something didn't sit right with him.", Pan whispered to Trunks.
"So did I. Let's get back with the others.", Trunks suggested before Pan nodded before Kibito Kai suddenly appeared.
"Kibito.", Pan spoke in surprise.
"It turns out my ancestor needs you both as well.", Kibito responded.
"Really? For what?", Trunks puzzled.
"Does Grandpa need help up there?", Pan asked.
"Well, uh, you could say that.", Kibito responded.
Some time later, Trunks and Pan, with Giru in tow, were escorted to the Land of the Kai's.
"Wow. So, that's the Land of the Kai's?", Trunks asked.
"Yeah. The place where Papa got his hidden potential unlocked.", Pan responded in surprise as she and Trunks looked around.
"Hey!", Goku shouted before Trunks and Pan turned to see Goku chuckling.
"Hi, Grandpa.", Pan grinned.
"So, why did he need us up here for?", Trunks asked.
"For your training, of course! If you're going to make certain the Legendary Super Saiyan is stopped one way or another, then you at least need to train.", Elder Kai responded.
"What? We're actually training together?!", Trunks and Pan spoke in unison before Goku chuckled and it then zoomed away from the trio before it then showed a far away view of New Planet Vegeta with Broly on the top left, Bulla on the top right, and Goku, Trunks, and Pan (the last two of which were quite surprised).
Narrator: "Much to Trunks and Pan's surprise, they were summoned by the Elder Kai in order to train with Goku. But what would be the end result of their training? And can they finish in time to thwart Paragus' plan and save their home? Next time on 'Dragon Ball Super GT'!"
