Patton and Logan are opposite Sides.

1. We don't have any evidence that opposite Sides have to be a 'Light Side' and a 'Dark Side'. The Creativity Twins are an example of that but until we know who's the opposite Side of who, there's no way of truely knowing.

2. Logan has no emotions and claims "Ah, emotions. The bane of my existance." Patton, on the other hand, is full to the brim with emotions, he represents Thomas' heart.

3. They stand on opposite sides of the room.

I know this is a bit of a weak theory but I came up with it when I was half asleep. Tell me what you think in the comments.
