(This is not in the show. This is a scenario I came up with from a dream I had🤣)

Optimus, Arcee, Bulkhead, and Bumblebee were in their alt modes on patrol. They’re watching over humans right now at a school dance, specially Prom and they’re parked on the grass, some people walking over and taking pictures in front of mostly Optimus, or Bumblebee, completely unaware of what they truly were. Until they notice you. They notice that you continue to glance at them which makes them think they’ve been caught. But who truly knows, they’ve been gawked at all night long.

Optimus: sitting in his alt mode silently, almost learning more of the humans ways.

Arcee: sitting silently in her alt mode, doing nothing else.

Bumblebee: staying quiet in his alt mode.

Bulkhead: doing the same. Sitting completely silent in his alt mode.
