[Insanity? Oh he knows Optimus. He knows this very well. He's not so deluded that he's not aware that his own mind is broken beyond repair. This self-awareness allows him to view the world with an amused eye. These pitiful creatures cannot see what he can see. Optimus though. Optimus understands him.

Or, at least.

His Optimus did.]

Ahh, but some paths must be followed. Others must be destroyed. That is the way of things. The way of you and me.

I've killed my Optimus Prime, you know. Destroyed him and his people.

[He says, despite a small voice in the back of his mind wondering, hoping, that maybe he is wrong.]

He destroyed the one thing that could have restored our burned and ruined Cybertron to stop me. [He laughs.] And he suffered for it. Would you have done the same, I wonder? Destroyed something so infinitely precious to protect the weak?

I'm curious.
