"I would have done what he asked, I think. I would have done it, and Rodimus would have blamed me for that as well."

He shakes his helm, though he is thinking a bit more analytically now. Much of Megatron's plans took a while to fully sink in - the entire thing had felt so out of nowhere, from his perspective at the time.

"Megatron had been intending on forging the Matrix into something he could use. I am not sure what would have happened, bringing such powerful artifacts together."
