He hated waiting. Especially now. Now that his brother was out there. Especially now that he physically couldn't look for him.
So, when the door finally opened Dean jumped to his feet,almost passing out in the process.

"Dean! hey hey,take it easy." Sam said,at his brother in seconds, provisions forgotten in the entry way. Guiding Dean back to the hotel bed,Sam shook his head, "You really shouldn't be moving around."
Dean closed his eyes, hoping the room would stop spinning and swirling around, "You really shouldn't take two friggin hours getting pie." he said wishing he sounded more annoyed than he actually did. His weariness and pain betrayed him.
After getting his brother settled, Sam picked up the bags and started sorting them to their appropriate places, "Admit it, you were worried."
"Shut up."
"You were worried,weren't you?" Sam asked,sitting at the room's greasy table.
"Sam. Please shut up."
"Just say that you worried. It's perfectly human to be worried-"
"If I said I was worried,would you please shut up?"
"Dean, you don't need to act all stoic-"
"Sam. Look,I'm a little banged up-"
"You have a concussion and 3 broken ribs,Dean. You're more than a 'little' banged up."
"Hit it on the money, Sammy. I'm concussed, so please...please shut up. "
Sam went quiet,watching Dean get carefully under the blankets.

A few hours later just as Sam was crawling into bed, he heard a mumble.
"Was worried,okay? Now,shut up and got to sleep."
Sam grinned, "Can't sleep, neither can you."
"I'll be good."
"Nope."
"Sam."
"Dean,shut up and rest already."
After a minute, there was silence. Satisfied, Sam flipped open his lap top with a small smile.
