Vincent had been pretty quiet as they made their way up through the Labyrinth- he didn't have much choice but to be quiet, really, given he was still fully paralyzed. Alexander had been strong enough to carry him without much trouble, and it had been a quick journey. He'd also stayed quiet as they reached Thoth's Guild and confirmed the nature of the potions. 

[i]"...um, s-so, the antitoxin I made...might have accidentally gotten mixed with a paralytic I was working on by accident."[/i]

That silence was broken as a violent, angry groan escaped the man's body. As the Goddess continued, the groan became even more aggressive.

In a small way, Vincent was glad he was paralyzed at that moment. Gods knew what he might have tried to do to Thoth if he wasn't.
