Other mistake: Hawk gets a mohawk, but his hair was too short to style it like that.
Suggested correction: The mohawk was not a prop, but the actual hair of the actor they shaved off and mended together for him.
That is true, it was the actor's actual hair, but in the realm of the show, Eli's hair was not long enough to style that large of a mohawk out of it.
Continuity mistake: Johnny's car gets hit, and he comes up and starts banging on the windows. When the girls drive off, the rear window is down, when it wasn't prior.
Continuity mistake: When Daniel threw his Crane Kick in the '84 movie, Johnny fell back and crawled away holding his nose as Daniel jumped around on one leg. But in the opening scene of this episode, Johnny is now prone on the mat as "Daniel" stands there in fighting position.

Continuity mistake: While Daniel speaks with Cole at the car sales lot, the window of the truck beside them is up and down at least two times between shots.
Revealing mistake: When Johnny shows up to Cobra Kai dojo and all the kids are there. In the video playback they show on the phone you can see Miguel didn't land the kick, and the kid just fell down. (00:28:18)
Continuity mistake: When Johnny leaves his home to go to Daniel's place it's night time but when he gets there suddenly it's daytime.
Suggested correction: Daniel lives far away. Johnny must have driven all night.
That implies that Daniel lives like 5-6 hours from his job.
I actually assumed that it was already like 6am or something like that and knowing how sprawled our everything is there figured maybe it was like a 40 min drive. But then Daniel's wife also says it's Saturday morning yet Miguel and Sam are in school.
Factual error: Johnny gets a personalized license plate that reads "cobrakai", which is 8 characters. California license plates only allow 7 characters.
Continuity mistake: When Daniel is fighting Robbie's former friends on the beach, you can see a ship in the ocean behind him. The camera then cuts to his opponent, and then back to Daniel and the ship is gone.
Continuity mistake: When Sam and Tory are at the party, they both get two shots of vodka in the purple cup. Tory drinks the vodka, but after a while the vodka reappears.
Continuity mistake: Miguel kicks and breaks a staircase railing during the school brawl. For a second it cuts to Robby. When it cuts back to Miguel, the railing is fixed.
Revealing mistake: When Sam and Tory confront each other at school, the same extra (a girl wearing glasses) appears in two different places. She is behind Sam during the confrontation but Robby also runs past her in another shot.
Continuity mistake: During the school brawl, Miguel tries to stop Tory from further hurting Sam but Tory kicks him aside. Tory's jacket comes off her left shoulder. It then cuts to Miguel and when it cuts back to Tory, her jacket has come off both shoulders.
Continuity mistake: Miguel and Hawk are in the same class when Tory hijacks the announcement. When she meets Sam in the hallway, Hawk is now in the crowd behind Sam, but Miguel is just leaving the classroom and running through the halls.
Continuity mistake: During the school brawl, a teacher tries to break it up only to get body slammed. Hawk is flinching at this in the close-up. In the wide shot, he is kicking someone.
Other mistake: As Sam recovers from her injuries, she keeps babying her right arm, when it was her left that Tory scraped with the wrist chain and bandaged.
Suggested correction: It was her right arm that Tory cut.
Audio problem: The man Larusso neglects to sell his dealership to thinks he just got the deal before being punked. He turns around to talk to his assistant but the audio here is off enough to be noticeable. His mouth doesn't match briefly.
Revealing mistake: When Daniel (Macchio) sees Kumiko (Tomita) dancing in Tomi Village Green, several U.S. service members are watching. Close inspection reveals they are wearing no nametapes, rank, or branch tapes on their uniforms. All that is visible is the bare Velcro sections.
Other mistake: Johnny is browsing Facebook and accepts a friend request for his childhood crush and checks out her profile. The Facebook post on Ali Mille Schwarber's profile with a photo of her smiling has a lock icon next to the date. This indicates that the photo/post is private and no-one should be able to see it except for Ali. (00:36:58)
