It makes Arcee's spark heave to see him so wrought with emotion over this -- over Megatron. But she can't even bring herself to be angry over that. It was never any secret, Optimus's past ties to Megatron. The betrayal of one of his closest confidantes had always motivated him to find a way to bring an end to the war.

"I know," Arcee says, surprisingly gently, but her voice is still thick with resignation, full of emotion of her own. "I know. But it's been seven thousand years, Orion. Some people...some people change. Not Alpha Trion, no -- but..."

It's a waste of trying to convince him only on her word, though. With only a flicker of hesitation, she draws closer again, this time to disconnect the infusion pump. Her hands are slow, careful; memories or no, Matrix or no, he is obviously still someone she cares a great deal about. "There's a stack of datapads next to my recharge slab. Autobot records, journals, research...some of it came from the archives at Iacon itself. If you really want to know what happened, Orion -- if you're really concerned with the truth...I think you owe it to yourself to look at both sides of the story. Draw your own conclusions. Don't let me -- or Megatron -- decide for you."
