The Power of Love? (Dark City Post Volume II)

So, John and Anna walked off into the sunset after John's revolution from the Strangers. And as we discussed in class, we know they will be together forever. But is that going to happen because Murdoch has designed it to be so in his mind, or has he simply set up the parameters of an experiment in which he can control, but choose not to control, the outcome? Basically, what is going to make Anna/Emma fall in love with him - his control of her or a deeper, more powerful force? If we are not the sum total of our memories and there is a human spirit beneath it all, is love the emotion that seeps through this inner layer into our concious state and remind us that it is there? Or better yet, does it prove it is there?
