Autobots TFP

Optimus, Arcee, Bulkhead, and Bumblebee were patrolling in their alternate modes. They were keeping an eye on the humans at a school dance, especially the prom, and were stationed on the grass. Some people approached and took pictures of them, mostly Optimus or Bumblebee, unaware of what they really were. Until they saw you. They noticed you staring at them, which made them think they'd been spotted. But who knows, they'd been watched all night.

Optimus sat in his alternate mode in silence, almost learning human customs.

Arcee sat silently in her alternate mode, doing nothing else.

Bumblebee remaining silent in his alternate mode.

Bulkhead doing the same. Sitting in complete silence in his alternate mode.
