During this particular episode, I noticed two flaws and one dubious title.
For starters, Phong summoned Bob and Dot Matrix to the Principal Office because of recent tragedy involving Megabyte and Hexadecimal joining forces despite the fact that Enzo Matrix, AndrAIa, and Frisket had not rebooted yet. You must catch this episode to comprehend what I mean.
Secondly, Bob approaches Enzo Matrix and soon is face-to-face with him. Then in the next scene, he is back to being behind the judge's podium.
And lastly, why is the title of this episode "Number 7" when it was Number 1 Enzo Matrix sought? There are no references to Number 7 at all throughout this episode.

There is no way this episode makes sense unless you are a fan of "The Prisoner" television series. The Prisoner, a secret agent who quits in the opening credits every episode, is brought to The Village to have headgames played on him by a series of "Number 2"s. The Prisoner is Number 6. Why they call Matrix Number 7, instead of 6, is a mystery to me. The last scene is straight from the last episode of The Prisoner, including the big SPOILER: Number 6 IS Number 1.

No, nothing was very clear the first time I saw The Prisoner, and repeated viewings have merely added to the confusion.

Bloody dream sequences! Nits like Matix bouncing around in the courtroom scene could be just a product of Matrix's fevered dream.

Instant title theory! This episode is the seventh of season three.

Hmmm....When Enzo entered the games, he was 10. So why is he arguing with his 01 counterpart at the end of this episode? Is the dream sequence trying to tell him he's denying the memory of everything before "Talent Night"?

(Yes, I know--it's 01 to fit in with the Prisoner storyline. As Phil says, "I don't deal in reality.")

The golfers at the end represented "Tiger" Woods, Greg (the Shark) Norman, and either ChiChi Rodriguez or Lee Trevino (the sombrero).

Episode 7 of season three:

This has to be the best written episode of the entire series, never mind the Prisoner homage! It's not about defeating the user or some other external treat. It's all internal, all about the way Matrix's character has changed, perhaps not for the better. At the start of the episode Matrix exclaims,"I quit." Like The Prisoner, he's resigned.
Those moments when they speak in Hexadecimal's and Megabyte's voices are priceless, "Bob, I need you to...TRUST ME."
The rest is simply a clever collection of Golf and Prisoner references.

That last dialogue between Matrix and "Number One" --little Enzo-- is the best written scene. Something that relates to real life.

AndrAIa reboots, interestingly, as the "old" Hexadecimal, before Herr Doctor's modifications.

Had AndrAIa seen the rebuilt Hex?

Yes, she did, at the end of "Firewall".
