June 8th excerpt:
The brothers only remained up for a few more minutes. Dean did a quick check of Sam’s temperature and made sure no new injuries had cropped up during the harsh night.
Once he declared Sam as fit as he could in the dark (and Sam grew tired of Dean’s mothering), they pushed the napkin with the remains of the food to the side, both took one last drink of water to help re-hydrate after the harsh day, and then curled into the folds of the handkerchief.
