Greg looked back at him, reocignizing the fear in his eyes, the shaking the tears. He had seen it several times already on vitcims to kidnappings and the like. It was a normal reaction. But to see it on Sherlock, who was anything but normal..
He kept watching him even as he looked away. But he had finally managed to get him to look at him for a bit. "I'm going to touch you now." he said calmly, warning him to keep him from recoiling like he had before. Greg reached out, carefully placing a hand on his arm and left it at that for a minute. Then he slid a little closer and placed his other hand slowly on Sherlocks knee. 
He looked at him intently. "This is normal, Sherlock. It's a completly normal reaction, and I believe, no, I [i]know[/i] you can beat this."
Greg slid even closer and lifted his hands, reaching out once more. "I am going to pull you close now." And so he did. He lightly grabbed the other mans shoulders and easily turned and slid him closer on the smooth leather of the sofa. Careful not to put pressure on his injuries, he adjusted him against himself. He had one knee drawn up and resting against the back of the couch, the other down on the floor and Sherlock in between, his back resting against the drawn up knee and held in place by his arm around his shoulders. Gregs other hand was on Sherlocks knees. 
"Is this alright?" he asked softly, just in case, slackening the his grip on the man who was leaning against his chest now.
