"Maybe....I didn't want anyone to get hurt..." Vincent says softly. That's why he was where he was. There was no one around and the room seemed promising, so he wanted to try that first. He bows his head a bit, trying to hide the fact that those tears are actually there. "Maybe." He could've left as well, not come back to this place like he did, or he could've had more control over his anger and the like. Or just stabbed him once or twice, stabbed him in the wrist to get away or something instead. He's running through scenarios in his head at the moment.
