One of Duster's eyebrows twitched when Aoi turned to him. Akane's Shadow had targeted him with accusations that he didn't care for, yes, but she didn't walked up to. They weren't as close as Duster was with Aoi. His fists pulled away from the Shadow, though his hurt eyes continued looking into those purple eyes.

"That's not true," he replied in a forced, steady tone. "I trusted you. I really did, and...it hurt to leave you."

He mouth tightened until his lips had all but disappeared. To most people, he looked nervous or angry, and while both were a little true, anyone that knew Duster could tell this was a sign that he was thinking. Mulling over his next words, allowing for as few mistakes as he could.

"...I'm here to help. I want to know why you did that."
