Oh boy...I know lots of people talk to death about how this arc ended. Whether you hated the arc or not, this is not what I'm really focusing on. What I want to talk about is the fact that by going by what has been said and seen in this three parter, it seems like Orion Pax was not the holder of the Matrix, but a host. Think about it: Without the Matrix, Optimus Prime disappears and Orion Pax appears with no memories of what his "alter ego" does. Optimus Prime is literally the Matrix's ideal leader. It's like the Matrix is just using Orion. That's .... whoa. Maybe I missed something or not, I really need to watch the episodes again. I'm just going by memory, but it makes me question the Matrix there.
