Meredith is distinctly aware what side of that argument she falls on, although she can't say they don't know what they're doing, if only because she doesn't know enough herself to have a leg to stand on. Arms wrapped around the sack, she slips out ahead of him, struck by how much she doesn't want to do this. It's easy in there to say they'll be fine, but as she makes her way down the path, keeping as much in the shadows as she can, she's also aware that, if anything happens, no one's going to care if she's a professional or not. The return to the truck, she can manage just fine, but she keeps glancing at him for confirmation even so.
