Warning: The following contains spoilers for Season 4 of Cobra Kai.

The world of Cobra Kai reintroduces fans to the Karate Kid and the rivalries present in those movies, but it also brings the audience a great combination of new characters with some impressive skills. The series isn't just about who has the best kicks on the mat though. It's also full of some great lines.

While there are plenty of funny one-liners throughout the series, there are also some great words of wisdom. In fact, most of the memorable lines in the series are a result of characters saying some surprisingly wise things to one another.

Carmen Gives Johnny Some Advice:

"Never Mind Your Past Mistakes; Don't Let Them Determine Your Future."

Carmen talks to Johnny in Cobra Kai

One of the biggest themes in Cobra Kai is how the mistakes made by Daniel and Johnny in their youths continue to shape their lives. Neither of them can let go of the past. When Johnny starts training Miguel, his mother sees that firsthand.

It's Carmen who gives Johnny these pieces of advice, though it's easier said than done. She encourages him to be better than the mistakes he's made, but the rivalry between Cobra Kai and Miyagi-do persists. It takes Johnny four seasons before he actually starts enacting Carmen's advice instead of just hearing it. That's one of the things that makes the show so great: it's an uphill battle for the character arcs.

Sam Calls Tory Out For Her Bad Behavior:

"Everybody's Got A Sob Story. Doesn't Give You The Right To Be A Bully."

Sam takes a fighting stance against Tory in Cobra Kai Season 3

Though the series might be all about the Johnny-Daniel rivalry at first glance, some other (and better) Cobra Kai rivalries tend to usurp theirs as the story progresses. That between Sam Larusso and Tory Nichols, which starts as their interest in the same boy, but progresses to a difference in life philosophies, is at the heart of seasons 2 and 3.

Sam initially tries to take the high road. As she points out when Miguel defends Tory acting out, everyone in the show has had bad things happen to them. It doesn't mean that any one particular character should bully others. It's a solid point for the real world as well. Part of what draws so many of the characters to Cobra Kai is how unhappy they are and Sam recognizes that.

Kumiko Teaches Daniel About Karma:

"Put Good Into The World And Good Will Come Back To You."

Cobra Kai certainly enjoys bringing back blasts from the past for the audience to remind them of everything Daniel and Johnny have gone through. One of those is Kumiki, who Daniel originally meets on a trip to Japan. He meets her again when he's there for business, and after a lot of reminiscing and learning about Daniel's recent business troubles, Kumiko drops this gem on him.

It's right in line with most of Daniel's efforts in life. He doesn't want to start fights, and he just wants to do the right thing, but Kumiko appears to still be better at that than he is (though he's getting there).

Daniel Offers Some Inspiration To His Daughter:

"You Are The Only One Who Can Get Up When You Are Down."

Although Daniel Larusso and his kids rarely see eye-to-eye on anything, that doesn't stop him from trying to do right by them. Because he and Sam have their interest in karate in common, he tends to spend more time trying to inspire her than his son.

When Sam has a rough time in the third season, dealing with the trauma of her conflict with Tory and Miguel's injuries, she tries to push through and finds herself set back over and over again. Daniel reminds Sam that no one else can do this for her. While the show focuses heavily on the camaraderie of teammates and the bonds of family, it's true that each of the teens at the center of the story have to decide to stand up for themselves first.

Robby Sees Silver For Who He Is:

"Do You Want To Fight Him?"

While Cobra Kai's new recruits might welcome Sensei Silver into the fold as he and Kreese divvy up the training duties, Robby is a bit more hesitant when it comes to any sensei. He even trains one of the new recruits himself instead.

When it comes to the big matchup between Robby and Miguel in season 4, Robby grows tired of Silver encouraging him to use shady tactics, and suddenly asks if Silver wants to be the one on the mat. It's the perfect callout from the teenager because it's exactly what defines the show. The older generation is so invested in the competition between the younger because they feel like it's still their fight. The truth is that each of the kids is fighting for something else, not just which dojo should end up on top.

Sam Tells Johnny What She Thinks:

"I'm A Teenager Who Makes Mistakes. You're A Fifty-Something-Old Man Who Lives Alone [...] And Clearly Hasn't Figured Out His Own Life."

Although Johnny and Daniel have very different styles, they try to combine their efforts to take down Cobra Kai. Sam is one of the first to be behind the team-up, but she's also the only one to call out Johnny for his reckless behavior while training the group.

Johnny isn't the best role model, that much is true. Sam calling him out on that fact doesn't deter him though because there is one thing he's good at: getting kids to follow their karate dreams. It's interesting then that Sam is the one to learn the most from him. She never completely gives into her anger, but she's slightly less controlled because of him.

Johnny Drops Some Surprising Wisdom:

"If You're Not Strong On The Inside, You Can't Be Strong On The Outside."

Johnny might not use the best methods with all of his students - calling them names, putting them in dangerous situations, and offering up no training as an initiation - but he does make a very good point in his early days as a karate instructor in the series.

Though he tells the kids they need an inner strength when he's referencing them needing to change up their "nerd" images, Johnny makes a good point. All the strength training in the world won't help the kids if they aren't mentally strong as well.

Daniel Tries A Non Aggressive Approach:

"It May Not Seem Brave, But Sometimes, Avoiding Conflict Is One Of The Most Heroic Things You Can Do."

For the audience, conflict is one of the most entertaining aspects of the series. For Daniel though, conflict is what causes all the trouble for his family. That's why he keeps advising non-aggressive approaches, even if they don't always work.

Though the kids of Cobra Kai keep coming for Daniel's students, he's not wrong about heroes sometimes needing to walk away from a fight. Miguel, for example, is equal parts hero and villain in the overall story of the show, but he's doing his best to not give into his aggression in the later seasons and learn from his mistakes.

Aisha Reappears With Some Advice:

"I Set My Own Terms; Set Yours."

Aisha talks with Sam in Cobra Kai Season 4

Following the second season of the series, fans sadly had to say goodbye to one of Cobra Kai's best friendships as Sam's friend, Aisha, was written out with the explanation that her parents moved out of the valley. When Sam needs a little advice in season 4 though, she seeks out her friend in Santa Barbara. Sam is worried about Tory re-enrolling in school, so Aisha recounts her own story of "striking first" as she made friends with someone she thought was judging her.

Aisha provides a great example of how to apply what the kids are learning to the real world without throwing a punch. It's exactly what Sam needs to hear.

Sam Finally Talks About Her Trauma:

"Sometimes The Scars You Can't See Are The Ones That Hurt The Most."

Sam spends a lot of season 3 pretending to everyone that she's just fine. It's not until the All Valley Tournament is in jeopardy of being canceled that she finally speaks about her trauma, without referencing it directly, to an audience.

Sam and Miguel both speak at the public hearing regarding the tournament, and it's Sam who points out that the tournament gives the kids a safe place to fight, an outlet for everything they're going through. She's still got literal and metaphorical scars from what she's been through, but she doesn't want to give up.
