Is the Oracle a traitor?
Ok its obvious code can be inserted into food, the Mero showed us that. The Oracle could have made cookies that would make Neo feel better after her first conversation with him. Notice the candy she gave him in Reloaded? Looks a lot like that red pill... The red pill that located Neo in the real world.
I think the candy had something to do with reading Neo's mind. Look at the Architects monitors. Its has Trinity dying before it actually happens. The Archt can also read Neo. Maybe she isn't exactly a traitor but her purpose it to make people believe they have a choice when they really do not and too make sure the one makes it to the source.
I also do not know if Mero is as bad as we like to believe. He tried to show the three that there was no such thing as choice in the matrix. its all causality he wanted to make sure the woman would give him head, so bam there is some cake, the piece of cake that would take away the why and reason forcing her to make a trip to the ladies room. She had no choice in the matter....... AHHHHH... my head hurts...... I am tired i gotta go to sleep... causality...
