Character mistake: Considering she was wearing heeled boots, Ms. Underwood should have either taken her shoes off or at least have had a carpet provided to her if she was going to sing on the competition mat, as her shoes could have torn it.

Trivia: Minor spoiler: In season 2, Johnny reunites with his old Cobra Kai buddies. One of them, Tommy, has been ill for some time. They go on one last ride together, and by the morning Tommy has died. Robert Garrison, who plays Tommy, went through something very similar. Robert had been ill for some time, and got together with the actors for one last reunion in this episode. He sadly passed away on 9/27/19, just months after the show aired.
