Cynthia is a vampire unrelated to the coterie, but is Jason's girlfriend, she is slightly older than Jason, having turned in the early 2000s in her early 20s. She stays out of politics and she stays out of the Sabbat's way, generally not taking a stance. She's smart, witty and knows how to survive.

So in the scene Cynthia is pleading Jason to leave this house, which at this point is teeming with dangerous monsters and dead bodies, she can hear an overpowering voice screaming in her head and is concerned with Jason's nonchalance about the whole situation and is trying to snap him out of it. The stakes are high super high!
