Amanda: What happened?
Daniel: Terry Silver happened. He's this certified wack job from my past who come back to Cobra Kai.
Amanda: Another one? Seriously, Daniel? Are there any other Cobra Kais from your past who are going to come out of the woodwork and destroy our lives?
Daniel: No. Well, I can't say that for sure.
Amanda: Oh my god.

Daniel: You know we don't agree with aggression that's not how we act.
Sam: Maybe that's not how you act, but I can make my own decisions.

Daniel: Whose side are you on?
Sam: I'm not on anyone's side. I just want to learn both styles so I have twice the techniques if I face Tory in the tournament.

There are three things that make a champion. The three D's. Desire. Devotion. And discipline. The first two I can't give you. The last one I can, but you have to be willing to receive it.

Silver

Miguel: So if you win we just train Eagle Fang, there's no Miyagi Do.
Johnny: That's right, Pontiac.
Miguel: But what if I don't want to stop learning Miyagi-do.
Johnny: What the hell are you saying? You want him to win?
Miguel: No, I guess the way I see it no matter who wins nobody wins
Johnny: Somebody always wins. That's how fights work. No matter what ancient philosophical bullshit LaRusso has been feeding you

Kreese: I want you to know I'm glad you came on board, but I want to make sure that we're both on the same page. These things that you're teaching my students. Well, they're a little confusing. Cobra Kai never backs down from a fight. Tournament or no tournament, we always strike first.
Silver: But you already did.
Kreese: What are you talking about?
Silver: I'm talking about Robby Keene. You never told me that his father was Johnny Lawrence.
Kreese: What's it matter?
Silver: What's it matter? You stole the man's son. If that's not a direct attack, I don't know what is! And now you've got him and the rest of the kids wrapped up in all your old drama, and if you're not careful, it's going to take Cobra Kai down all over again.
Kresse: I've got everything under control, including Robby.
Silver: No offense, John, but that's not how it looks from where I'm sitting.

you were right about me John. I was living a lie. I lose who I was along the way, but now, there's nothing I want more than a second chance at finishing what we started. I just want to make sure that this time, we win. And the only way to do that is to forget about the past. Focus on our students. We do that and everything falls into place. Larusso will have to shut down Miyagi Do and Johnny Lawrence will rue the day he ever left Cobra Kai.

Silver

Johnny: You still think that your way is the only way. You were so proud when they pulled their little sprinkler prank the other day. But if they stood their ground and kicked some ass like I taught them this would've never happened.
Daniel: And if they fight every time they're provoked where does that lead? Back to the hospital? Or to jail? Just because you spent your fair time in both-
Sam: Enough, dad. Johnny's right. Doesn't matter how many times we stand up to Cobra Kai if we don't strike back they're going to keep coming at us.
Daniel: And you were worried about my influence on your students? Is this what you wanted Johnny? To have my daughter and the rest of my students acting like you?
