Cypher aka Mr. Reagan was the betrayers name.
i'm working on the scoop on tank :P
best i can find:
2. In the six months that elapsed between the plots of the first and second movies, what happened to Tank, the driver who saved them all in the first movie?
Marcus Chong, the adopted son of Tommy Chong (one half of Cheech and Chong), is gone. Neither the studio nor Chong would comment on why, but Warner Bros. replaced him with Harold Perrineau, the guy in the wheelchair from HBO's Oz. Chong told Entertainment Weekly that after he was replaced he tried to crash a Matrix press junket and he took food from the Matrix lot.Source
as for the fighting question, well alot of folk seem to be asking this.
I have to think, ok your Neo. You just got done talking with "Her" and you get caught off guard, you do not "know" Smith can replicate himself. you start to fight and really are just thinking, :censor::censor::censor: i killed you already. I'll do it again. Only later after many a funny toss and tussle do you realize this isnt gonna happen. And are trapped, you explode in last ditch effort to flea.
He's a hero, he's brave, he think's he's supposed to save the world. This isnt usually done by running away unless you know there is no other way.
Also recall, all three times he flew, were explosions of emotional and mental strength, first because he thought he was dead and second because he knew he had to save the keymaker, third to save Trinity. Quite a bit of theme going there. Flying i'm sure takes a great deal of mental capacity to "believe" he can do.
Of course these are just my speculations
The architect speach, you really do need to watch this again if you didnt catch it the first time, however if you follow the tangent he's saying that it was Neo's destiny(sp) to make it to the source, that he's designed to do so and lead to that end. Why? because the matix isnt perfect much to the architects woe's it has anomalies, and every so often they have to use 12 people to find and destroy these anomalies. The believablity of the matrix is questioned without "Choice" the only way to make a successfull matrix is to give everyone the illusion of choice. So Neo is given the choice, door 1 the source and the end of the matrix and machines (wich cannot happen-ill cover that later). and door 2 saving Trinity. Knowing he has already made his choice as the oracle has already seen. this isnt really a choice. And we all know what he chooses
however! i have to wonder, why would the archetect be telling the truth? Is this just another tactic to keep him from the source? I mean they cant beat him physcially so why not try mentally?...
I have to agree with Tybolt, after he saves trinity, you'll accept that they are stil in the matrix, but when do you see them go to a phone? All they show is him being unpluged and then the running from "the bomb" and theres another question or two... how is it that neo knows its a bomb, and how did he get special powers "outside" of the matrix, and he even says it "wait, somethings different, i can feel them."
have they really left the matrix at this point...
ok earlier you remember the conversation with the counciler(sp) of Zion and Neo where they discuss the dependency of man and machine, i think Neo is already questioning the reality of humankinds ability to function without machines. This is further supported later by the Oracle. Making door number 1 even less attractive.
