Good omens

You accidentally find yourself "drawn into" their latest adventure. Perhaps you witnessed something supernatural, and they've decided to "kidnap" you to erase your memory (or protect you).
Queen's "Don't Stop Me Now" is blasting from the car, and the world outside is a blur. You're sitting in the backseat of a Bentley, which has miraculously adjusted to your height.
"Crowley! You'll scare her/him! Slow down!" Aziraphale turns to you worriedly, clutching the door handle.
“They’re fine, angel! It helps clear your head,” Crowley turns the wheel sharply, ignoring the laws of physics. He glances at you through the rearview mirror. “So, human. You saw something you weren’t supposed to. Now we have two options: either I turn your memory into mush, or you tell us why that guy with the flaming sword was chasing you. Which will you choose?”
