Tessie was attacked by Quentin Collins in his werewolf form (808). The doctor was unable to save Tessie, but before she died from her injuries she briefly regained consciousness and was able to say Quentin's name. Quentin had known Tessie from the Blue Whale tavern (809).
Sometime later, during a sudden lightning storm, Tessie's ghost appeared before Gregory Trask warning him that the beast is in Collinwood. She then appeared to Quentin, taunting him over her death (830).
