Huddled low, and Seacrest is squinting at the oh so inconspicuous 18 wheeler just sitting pretty at the gas station, very slowly tilting his battle card to watch the picture 'transform' between a blasters up mech and a big red and blue truck, trying to match the image to his target.
I mean, how many red and blue 18 wheeler trucks were on Earth, the same two red and blue shades as Optimus feckin' Prime, and had a very not standard issue symbol on the grill. He certaintly wasn't your average Mack or Kenworth.
No. That parked up piece of Prime literally machinery had to be Optimus. And who knew how much longer a mech like that was just going to be stationary.
In a body of water? Seacrest could keep pace with ease. Dry land? Two legs? No way he'd keep up with Ol Smokestack once he hit the highway.
".... Are you a plain truck, or are you an Optimus truck?"
Which is probably why Optimus is getting a very hesitant digit tip tapping the back of the trailer roof.
Oh, scrap. Did he just tap his aft?!
