Dean was surprised he was allowed to get out alone, but maybe Sam needed time to himself too. Maybe they both needed to just take a few minutes to cool off and prepare for whatever the Hell they planned to do about any of this. Maybe eventually they could have some damn fun, but either way it was easier not to rush things. One day at a time, he supposed.
Getting beer only took a short trip to the nearest gas station and Dean came back within an hour, with two six packs, and some snacks, dumping it all on the coffee table.
