Optimus drops the tool he's clumsily trying to use, letting out another cry of frustration. He looks up at the sound of Akechi's voice, and his optics widen, leading to him holding up his hands to show he's unarmed...or as unarmed as he can be with smokestack blasters on the backs of his arms.

"I'm sorry if I startled you," the Autobot says. Really, it's something Akechi should be saying, but Optimus doesn't want the human to be afraid of him. "I'm trying to get this vehicle working again. We seem to be meant to using these...or at least, those of you who are small enough to ride in one. I wanted to fix one as a sign of good faith."
