(I had a dream about this so this is NOT cannon to the show at all)

you, Optimus, and Arcee are doing an underwater mission to locate energon and there’s a relic you all have to collect too. It was a relic that had randomly popped up on radar and it must’ve been one of Solus Prime’s relics that she created way back when that Alpha Trion sent for Optimus in help to get Cybertron restored. You all hear a noise, however and you are uncertain of what it may be since you all are unfamiliar with humanity’s different types of wildlife.

Optimus: “Arcee, {name}, we must proceed with caution. We do not want to risk harming the wildlife, nor do we want to allow ourselves to get harmed.”

Arcee: “copy that, Optimus.”
