Darius sighed deeply as he saw Edward approach, his stride showing his rage as clear as day.
"Kristen, a word?", Edward said.
As he spoke his voice carried obvious tones of anger, perhaps even hatred. Darius instinctively gripped the hilt of his blade as Edward raised his voice. Anyone on the squad knew it only took a second, perhaps less, for Darius to kill a man once his hand was on the hilt and the target was within striking range. He waited patiently for Kristen's command, however. If she had instructed him to do so, he'd of cut a man he considered a good friend down without hesitation. This was how deep his loyalty ran, loyal to a fault perhaps.
His face remained emotionless and he remained silent but his body language sent out a clear warning: "Walk away, cool down or bet cut down." Darius had hoped Ed would see how he was being controlled by his emotions, but in the event that he didn't his hand remained firmly gripped around the hilt of his katana. One strike and this confrontation would be solved, one strike or one good judgment call on Edward's part.
Edward continued to yell, his anger obviously building. Darius turned to Kristen and awaited instruction, if he struck him down without her say-so he'd be reprimanded or worse. After Edward finished his rant, he appeared to calm down, but Darius knew better. The rage he displayed moments earlier proved he was still boiling over inside, and that was dangerous. Dangerous because he had a weapon, and dangerous because he seemed to lack the control to restrain himself properly.
