Had Optimus wanted to stay put, he wouldn't have budged. But as it turns out, despite his protests, he wanted to spend more time with Shockwave. Catch up on the time he'd lost. His head dips accordingly, humbly following him as elegantly as he can (which is pretty funny to watch, compared to Shockwave's natural elegance).

His ears flick gently, turning to face the Senator as they make their way onto the dance floor, casting a soft glance to the others.

"If it's acceptable to you, then alright."

Because he doesn't really care about everyone else--it's Shockwave he doesn't want to disappoint.
