So Miguel and Sam still convinced the board to allow the All-Valley tournament to stay, and they'd be celebrating at the Miyagi Do dojo. However, they wouldn't get touchy or try to start to do any kind of moves since Miguel was still recovering. This is when Robby would show up. He'd ask Sam what Miguel was doing there, and she'd explain everything to him. "So...you guys got the tournament back together. That's good." Miguel would still want nothing to do with Robby. When Robby would get closer to Sam, Miguel would back away. Robby said he wasn't going to do anything to him, but Miguel still didn't trust him. Sam then asked, "I've been so worried about you. Why didn't you respond to my emails?" Robby explained, "I...was in a bad place. In juvie, there were a lot of guys trying to start fights with me. As I started trying to respond to one of your emails, one of those pricks unplugged my computer. I wanted to respond to them. I really did." Sam then further explained to him. "And my dad...he didn't mean to betray you. He wanted the situation to go as well as possible, the police just arrived too soon. He wanted to explain the whole process to you." Robby was annoyed to hear this, but he remembered Daniel's teachings. "Yeah, Miyagi Do is about forgiveness, so I can see why he'd do that. I see how it was just a bad situation. And Miguel..." Miguel sternly said, "Fuck off. Don't talk to me."
"Fair enough, I'd have reacted the same way. But I want to say, I'm really sorry. I never intended for all of this. I just wanted to finish the fight. I had tunnel vision, was blinded by rage, and in all honesty...I barely knew where we were. I'm so sorry for bringing you to your lowest point, and if it's any consolation, it was my lowest point, too." Miguel stared, surprised. "Y'know what, I'll take it. And I'm sorry for kissing Sam. I shouldn't have done that." Robby nodded. He then told Sam, "I'd like to join Miyagi Do again...if you're fine with that." She smiled. "Yes. I'd love that." A few days pass by, and the day of the Christmas party comes. Miguel and Sam invite both Miyagi Do and Eagle Fang to the party. The conversation goes a fairly similar way. Then, Bert hears a meow outside, and goes to check on the cat. He gets thrown through the window, and the Cobra Kais come in, and then Tory comes in with some more from the front door. The fight starts. As Robby is fighting another Cobra Kai, he sees Miguel getting attacked and thrown by Kyler. He quickly knocks out the person he was fighting by a kata followed by a face kick, and then he rushes in. As Miguel had taken several punches to the ribs, Robby kicks Kyler right in the liver, greatly stunning him. Miguel then knocks him over with a kick to the face. As Kyler turns his face slightly, Miguel kicked him in the jaw, knocking him out. Robby said, "You good?" Miguel reassured him that he was. They continued to fight alongside each other and take down the other Cobra Kais. Meanwhile, Demetri was protecting the Bert and Nate, when Rickenberger took him by the arm, as another Cobra Kai was standing aside. They shouted to Hawk, "Yo Hawk, free shot!" And Hawk still has his moment of realization and saves Demetri. The two then fight the others off by teaming up and using combinations together. They then found Robby and Miguel, and Demetri said, "Don't worry guys, he's on our side now!" They all nodded. They looked around them, and all of the Cobra Kais except Mikey were down. Penis Breath was struggling against him, but that was quickly taken care of when Chris jumped into action, and took him down with a strong punch to the face. Some other Cobra Kais confronted them again, but it wouldn't take much time to take care of them. Meanwhile, Sam and Tory were still fighting. After taking a kick to the face, Tory tried to attack her with nun chucks. After the first few missed hits, she hit a photo of Mr. Miyagi. This caused Sam to get a boost of adrenaline, and pick up the staff. She blocked all of Tory's hits, and disarmed her, she then pushed her against the wall. She stared at Tory's eyes, and raised the staff up like she was gonna hit her, but she hit her in the stomach instead. Tory doubled down, causing Sam to spin around, and hit her in the jaw to knock her down on her back. As Tory was on the ground. Sam stomped on her belly, causing Tory to scream loudly in pain, which was out of character for her, and Sam began to beat her over the head repeatedly with the staff. Before she could do any additional damage, Miguel, Robby, and the others all arrived. Robby grabbed the staff as Sam was attacking. "The fight's over, we've already won." He looks at the picture of Mr. Miyagi, causing Sam to look as well. "Right..." Daniel and Johnny would still come back from the event, and see that their kids were attacked, so Johnny would go to the flagship dojo and confront Kreese. He'd intimidate him and get closer, so this time, Kreese would attack first. Johnny would be able to properly defend, and easily get the upper hand. This was when Kreese would take a weapon from his wall, and attack Johnny. He'd slightly cut him in the face while he was dodging. Thankfully it was just the a small part of his cheek that got cut. After a few more dodges, Johnny managed to attack Kreese's wrist and disarm him. He then took him down, and repeatedly punched him in the face. He was far more than knocked out by now. This was when Daniel would arrive. "Johnny?" This caused Johnny to return to his senses, and stop punching an already beaten-down Kreese. Johnny said, "He struck first, and cut me with the weapon." Daniel said, "Hell yeah he did. He ordered his students to invade my house, and he attacked you first. What you did was in self defense, and now...Cobra Kai will officially die. I called the police and they're on their way." About ten minutes later, the police came in and arrested Kreese. "Hopefully he spends the rest of his pathetic days behind bars." Johnny said, "Cobra Kai finally dies."
