Music definitely makes it easier to relax, and she's not about to rush the sharing and caring part of the drive. In a way, just having Dean right there and not off doing God knows what without her being able to help made her nerves chill out for the first time in a few days. Not that she has been able to help much with all the recent crap that came up.

Her fingers drum lightly on her knees along with the song, and she slumps back into the seat. Time to get comfy.
