To quote the Count of Monte Cristo - "we are kings or pawns" Neo was the first One who started as a pawn and became a King What happens to Alice when she reaches the 8th square This was hinted at all along Neo was the first One to go through the other door, save Trinity, who had to pilot the ship after Neo's fight with Smith, and then she dies, not in the Matrix, but at the city, the end of her journey Unlike the Matrix where Neo uses his power to remove the bullet and save her, now he has no such power As the Architect told him "she is going to die and there is nothing you can so about it" - which is of course what he meant all along - she doesn't die in the Matrix from the virtual bullet, because you have the power to stop that - she dies in the real world at the top of the City where you have no power - but you knew that Like Cagney in White Heat, Neo reaches the Top Of The World Like Alice, Neo has reached the 8th Square and is now the King (or Queen in the literal case of Alice) So Neo now The King can go into the Matrix and defeat Smith
