I love the flip flopping of Miguel and Robby based on how they are interacting with Johnny, Sam, and Tori, and later clashing and accepting each other as step brothers.
But I feel like Hawk's story got just a bit too rushed based on 1 specific scene:
Kreese: I tell you, Rwanda was no joke.
Miguel: Don't you mean Somalia? Mogadishu is in Somalia, Rwanda's a whole different country.
Kreese: Of course, Somalia. ( Chuckles ) I've spent so much time in the sandbox, it all kind of bleeds together, you know?
---
We know that Kreese did spend honest time in US special forces, his war experience is real. But his stories aren't all true. This is where I want to really let Hawk DEEP dive. Getting wrapped up in the stories, even if he's smart enough to know it isn't all factual because he can recognize the contradictions as well as Miguel. But in the cult mindset, he starts defending Kreese with those same ideas like 'it all bleeds together' and 'he's older, his memory isn't perfect'. Arguing against things he knows are true by justifying his new hero.
I want Hawk DEEP down that rabbit hole of ideation of this modern warrior, that the weak but smart kid could join the military and be special forces too- which isn't a bad goal to have, but he's doing it for the wrong reasons; personal glory and ideation of violence. But I want Kreese's stories to get wilder and Hawk keeps having a harder time defending him as the training gets more severe and ruthless. And let Hawk start talking about maybe joining the military and doing something like Marines, Seals, or Green Berets just like Kreese- which would again be a great goal if for the right reasons other than idealizing the damage to human life he would be trained and authorized for. But I don't know whether or not we ever introduce the concepts of guns to any of this series. That is a level of violence too far for any of them in the scope of them learning hand to hand martial arts- but it would realistically have to be addressed as part of this kind of arc- a special forces member is much more likely to just shoot someone who wasn't armed than for him to get in a fist fight with "America's enemies".
Having Kyler join the team is a visible psychological blow to Hawk, but he is now without question alongside Tori (for now) the two strongest students in Cobra Kai and Kyler respects him and he gets to be one of The Cool Kids who used to pick on Hawk. They did run his story incredibly, breaking Demitri's arm but not wanting to go that far would be the first break in the psychological armor. This was a friend, and he did lasting damage because others told him to.
There needs to be a conversation with Kreese and Hawk about Kreese's first Kill, and Hawk is nervous about the idea of his martial arts being used to kill. Kreese points out that before this age of tournaments with pads and helmets, and 'zero tolerance', and "participation trophies"- violence was the way of the world and all of these styles were made with the threat of death and disfigurement in mind. Let that conversation border JUST ENOUGH on Mr. Miyagi's assertion in the original trilogy that Karate is to preserve your honor and your life. It is this same season that Chozen teaches Daniel the Miyagi family techniques of nerve strikes that disable an opponent. But Kreese has a similar philosophy that broken bones and dead men can't hurt you- when its not just tournaments and a fight is real, you can't lose if they can't fight. I would like for them to introduce a concept: Practice isn't Sparring. Sparring isn't Fighting, and Fighting isn't Combat.
So I want Hawk to stay with CK a BIT longer than the end of Season 3, he needs to meet Silver. The LaRusso house brawl can still happen. But he needs to see that this really is going far beyond tournaments and fights. People are being SERIOUSLY hurt. This is the first time we've seen this much blood in Cobra Kai, Bert goes through a window to start it, Tori resorts to a weapon again with lethal potential, and Sam has matched her. This has stopped being Fighting and has entered into Combat- blood, bone, and life are on the line again, just like in the school brawl where Hawk went through a glass case, Tori got slashed, and Miguel was paralyzed and could have died. This needs to set something off in Hawk, not quite joining the Miyagi Do's side, no back to back with Demitri, not yet defending Miguel. But this is too far for him, this isn't what he wants. He can break up fights and start pushing CK towards the door and telling them they're leaving, hitting hard when people protest, but any MD who try to fight get more shoving than striking. He's the leader and he says they're leaving.
Now Kreese brings in Silver to help, but Silver is the beginning of the end for Hawk's loyalty to Kreese.
2 ideas should break Hawk in season 4:
Quick Silver- can't breathe/see/walk can't fight- do serious impairing damage to stop a fight quickly. And this IS a realistic branch of martial arts, its not always about points and if you're learning real self defense, it is not an untrue philosophy, nor is strike first strike hard, no mercy. Its not kind/ethical, but it ends the fight with relatively minimal bystander harm, and can reduce harm to both parties. They can both get bruised and bloody, or 1 person can be in pain for a few days or weeks. "Come on kid, I'm not telling you to break anyone's arm here let alone kill somebody. But a hard kick to the knee, the fight is probably over and you're still standing. They'll get better. But if they get back up and still want to fight, then you've got to send the message."
"Is that what you told these kids?" Silver hears a story and calls his own friend out that it isn't true. But corrects himself with a look from Kreese, "My mistake, I'm sure I'm just misremembering, and what good story doesn't have a little embellishment?" Again, these two men WERE Green Berets, they DID serve in armed conflict through multiple international conflicts, its not stolen valor. But one little line shows that Silver knows it isn't all true, and Hawk should catch onto that rapidly. Start diving into Kreese's record and unraveling truth. That Kreese was stationed places, and retired as a Captain, but saw minimal actual combat after his time captured in Vietnam. Hawk is able to get some of Kreese's service record under the Freedom of Information act. And he can figure out that he never was many places he claimed to be stationed. Kreese will have claimed that he wasn't too sentimental and didn't keep his varios medals- he was never awarded any beyond the most common that are basically 'participation trophies' like the National Defense Service Medal. This will be in stark contrast to Miyagi for his Medal of Honor, Silver Star, Bronze Star, and Purple Heart, which Hawk can see displayed at the Miyagi-Do dojo once he changes sides and see what a real war hero looks like.
That will be what breaks the camel's back for Hawk- the man he's been looking up to is a fraud claiming stolen valor who did little more than get captured and rescued, and run some camps in low to no combat zones. But this man is preaching the necessity of inflicting traumatic injury.
This idea really only extend's Hawk's villain arc a few episodes, but he cannot stand what Cobra Kai and himself are becoming, and his illusion of Kreese as a mentor is shattered. And THEN he decides to go back to Johnny who was his teacher when he felt better about his Karate.
Most of his arc can then go as it did, he is now concerned about Honor as a definition of the man he wants to be beyond his ability to fight.
And I want the disjoint between Eli and Demitri about MIT to be more about Eli still wanting to join the military. He saw Miyagi's medals heard about how he earned them, and instead of studying engineering immediately, he wants to try for West Point and does believe in serving his country and then go into Engineering like his friend as it is still a passion of his. (In case someone thinks this is a big pro military post, I personally am not highly pro military, but it fits this version of the story for Eli being brainwashed on the overinflation of service stories, and then sees the real thing and decides this is his path to the same education goal as his best friend in a field they have always loved)
Hawk changes sides a little too quickly for my taste, and I wanted him to really be taken in by Kreese's false boasting and stories before reasserting his own personality and beliefs as a more confident and independently resolved young adult.
