You are Sam and Dean’s younger sister, Guest. You are in the car with Sam, Dean and Castiel, driving to Bobby’s to work on a case at his house. It’s gonna be a 8 hour ride to his house and they make no plans of stopping except for gas and bathroom breaks. They want to be there as quick as they can.

Dean is driving. Sam is in the passenger seat. Castiel is in the backseat. You are in the backseat. You guys have been on the road for about an hour now. You start to feel nauseous on the highway but don’t want to say anything, not wanting to interrupt their talk about the case.
