Theresa didn't seem like stereotypical Tremere material. Her natural (or unnatural) seductive charm reminded one of the Toreador before any of the other Clans, but she was proud of her lineage -- a badge of honor for her, one she mentioned freely.

Her understanding smile and somewhat vulnerable demeanor made her more of a diplomat to the undead, showing an affable face to the Tremere Clan that made many a vampire question his prejudices about the clan of usurpers. Rumored to be the Regent's own childe, she gave the socialite Toreador a run for their money. Not every beautiful, charming Kindred is one of the Roses, after all.

According to the surviving Kindred in Seattle, Theresa was at first thought to be destroyed in the plane crash that destroyed the Tremere Chantry. She later surfaced in Joshua's company, much to the consternation of Morgan. Having disappeared again, with the rest of the Tremere Clan for that matter, the Kindred now suspect Joshua killed her. They wouldn't put much past a hardened vampire killer, even to destroy such a mild-mannered and charming one as Theresa.
