Sam is off the couch the second Dean's in the door, relieved to see him. He tries very carefully to keep his reaction normal, snagging the bag from his brother and rooting through it for his food. He could almost kiss him for bringing him a salad, but he's pretty sure that would be a bad idea.

So instead he sits at the kitchen table, working the plastic top off his salad and digging in with the fervor that Dean normally uses on a bacon cheeseburger. Food in his mouth means he doesn't have to talk if Bobby goes back to asking questions.
