Question: How did Drake discover the Nightstalkers hidden base?
Answer: It's possible that he followed one of them back to the base. This is feasible since they wouldn't be able to tell that he was following them because of his shape-shifting abilities.
Question: At the end of this movie the main guy is lobotomised and put back into the Cube. Is this supposed to be the start of the original Cube movie? Because the dialogue is very similar (about liking the blue room), but it is not exact and his name is changed.
Answer: No, the director himself has stated they're not the same person, however they wanted to show that Kazan wasn't always like that, he went through the same lobotomy that Wynn did It also, when viewed in that aspect, gives a much darker perspective to the ending of cube 1 when you realise that the "white room" was NOT an auxiliary exit, but rather one just like the room from Cube: Zero where the "god" question would be asked.
Chosen answer: Yes, it is implied that Kazaan and Wynn are the same person. The scenes are nearly identical except for the way Wynn is shown, as in, we don't see him fall from the room above as we did with Kazaan. But, yes, they are essentially the same scene.
Answer: Because the logo's a car registration plate and a number fits that structure better than just letters.
