And then at Dean's statement he blinked, then laughed, just once, "You remembered the bag?" He reached over to sling an arm around his brother's neck, scrubbing a hand over Dean's head, "This is why I keep you around, even in an emergency you remember the supplies."
Which included his laptop, for which he was also thankful.
