Leopold's ghoul. manages the majority of his business.

Allison serves as Leopold's ghoul, assistant and confidant. It is Allison who revealed to the coterie that the Second Inquisition had potentially damning evidence of the group acting as Kindred.

 
While originally an object of interest in Jay's self-proclaimed war against Leopold, after 'dinner' with Leopold and Jay, Allison has agreed to serve as a go-between for Leopold and Jay despite admitting to Jay that she is uncertain why Leopold chose him. She did assert however that Leopold often sees unlikely paths forward, so there must be some reason behind his actions.
