Anger in a logical mind doesn't run for very far without being then picked apart. Though initially it had been directed at Vincent, it quickly turned inward, was directed towards Terra and then passed her -towards Crystallis itself- all while the next part of the lecture was being phrased.

"Tantrum..." The way that Vincent demeaned all of Sephiroth's outburst into being so childish like that didn't sit well at all. Though he knows it had been his emotions riding him, at a level which he hadn't been able to reign in like he had before, to call it a tantrum...that's just insulting. He turns his head away again, reaching across himself with his good arm; slowing down the speed of the twist he'd made as the injury made it difficult, to take the half-full plastic cup of water from the side.

"You're right." He spoke again only after a sip of that water which was needed to clear his throat. "Those other things...my responsibilities, my duties...I've tried but-"

He'd left it for so long. Tried to move on. To carry on. There are larger things at stake. Sephiroth's eyebrows meet and drop in the middle again, but the expression is closer to that sadness than the anger that it's feeding. Touching at something deeper; the sense of no direction that Terra had been helping to guide.

"-it's just not worth it, anymore."
