It hurts to tell Shockwave this--As the one who led him down the path to being Prime, the one who outfitted him for it. And it shows in his eyes as he watches the Senator take it all in. Optimus had shared that dream too--of leading the Autobots with Shockwave at his side, as they should have been.

But nothing is as it should be.

"It was logical." Words that still hurt his spark to this day, but...were the truth. Shockwave, after empurata and shadowplay, had chosen what side was beneficial, not what felt right. A hand raised itself to go around his friend's shoulders to comfort (something he didn't do with many bots, surely).

"I'm sorry that I couldn't--"

Couldn't save you.
