Giving him a grateful nod, Graydon turned away.A heavy hand fell on his shoulder, causing him to stop in his tracks. Dragos' grip clenched, almost to the point of pain.Normally, Dragos was not demonstrative with anyone other than Pia and Liam. Moved, Graydon angled his face away. After a moment, he reached up to grip the other man's hand in return. Only then did Dragos' hold ease and allow him to continue on his way.
