Some mysterious things in Reloaded that might be good topics for discussion or essays:
When the Oracle says to Neo, “you’ve made a believer out of me,” what does she mean? A believer in what?
The Oracle tells Neo, “you’ve already made your choice . . .” But when did he make it? 5 minutes ago? The moment he met Trinity?
If Neo can fly away from the park where he battles the 100 Smiths, why can’t he fly to it in the first place? Why does he have to go through the special door?
Why does Bane cut his own hand with the knife?
Why does Bane start to attack Neo, then change his mind?

My thoughts, not in any particular order (and NOT responding to all questions!):

Re. flying:
Neo doesn’t fly to the Oracle, but takes the backdoors, becuase he needs to know about and understand those doors before he meets with the Architect. It will be interesting if neo learns to use those doors in “Revolutions”.

Re. Bane’s masochism:
I think Bane cut his his own hand with the knife because Agent Smith has never experienced (physical) human feelings before. I would think that everything associated with the human body would be fascinting to him, but Agent Smith’s very character seems to call for violence, even if self-inflicted.

Regarding choice, that was one of the few things the Oracle said that I felt I understood, perhaps more on an intutitive level than logically.

Where Neo is now, where each of us are now, is a result of choices we have made in the past. If Neo had not chosen the red pill, if he had accepted the word of the Oracle that he was not the one, if he had not stopped to talk to the spoon orphan, he may not have ended up where he was. Every one of those actions, large and small, led him there. The is not to say that he was destined or fated to end up “the one”, he could have made a different choice at any one of the junctures and it may have placed him elsewhere.

Our life choices shape us into the people we are today, and as we go along that path, there are times where we are forced into a situation because of those past actions. When we look back upon our lives, there are many situationa where if we had chosen B over A, our lives would be completely and totally different from what they are now, although at the time the choice was made, we had no clue that the consequences would be so far reaching.

If Neo had not fallen in love with Trinity, he may not have made the choice he did–he might not have made many of the choices he did, but it was ultimately his love for Trinity, and all his actions along the path to becoming “the one” that shaped his choice with the Architect.

That is, I think, what the Oracle was trying to explain to Neo. He is where he is (and we are where we are), because every action has consequences. Some are immediate, some are far in the future, some are positive, some are negative, but they are consequences just the same, and are something with which we must learn to live.
