"I'll be back later," he offered, looking down at the keys in his hands. "But you probably shouldn't wait up for me." He got the feeling that he was going to be out for a while.
He started to turn back, but hesitated. "We'll talk more about this later. When I've had time to just...process everything." He attempted a smile, but it barely crossed his lips. A useless attempt.
With all that he could muster said and done, Sam turned and left. He got the feeling that he was going to have a long night ahead of him.
