|“||They call me all sorts of names if I play the piano after dark for two minutes... But no one does anything when there's real bloody noise in the middle of the night.||”|
— Susan Ashworth talking about the noise being made by Joe Davis.
|Nicknames||''The Cat Lady''|
|Voice Actor||Lynsey Frost|
Susan is also the protagonist of the previous game in the series, The Cat Lady.
Prior to the events of Downfall, Susan was a severely depressed, middle-aged woman who pushed herself to suicide via drug overdose. Stuck between life and death, she met The Queen of Maggots who forced her into an offer; ironically, Susan was granted immortality until she killed five "parasites," sociopaths who commit heinous crimes. During The Cat Lady, Susan is revealed to live in a flat across the hall from Joe's flat on the second floor of the complex and has a few encounters with Joe, all of which were depicted as lapses of mental sanity but were otherwise harmless.
Near the end of Downfall, Susan is awoken in the middle of the night by the sound of Joe smashing down a door with a fire axe that he took from the hallway between their two flats. Irritated by the fact that her brief piano sessions received noise complaints but Joe's racket was ignored, Susan investigated his flat. Searching the apartment with no sign of Joe, Susan finds a rope and descends into a hole in his apartment's floor that leads into an empty, unused flat below on the first floor, hearing Ivy scream once there. Susan figures Joe to be a parasite and proceeds to construct a weapon out of various objects found between the two flats and yet another hole in the first floor that leads to the basement.
Susan is able to construct two different weapons, a cat skull scythe and a glass shard ax, in order to defend herself from Joe. After locating Joe in his hidden laboratory in the basement, originally thought to be Doctor Z's lab, Susan strikes Joe from behind with her chosen weapon, knocking him out before one of three different endings unfold.
Ending A, On The Run Edit
After knocking Joe unconscious, Mitzi arrives looking for Susan. Appalled, Mitzi suggests that Joe might have been starving his wife considering how thin she was. The resuscitation machine reactivates suddenly, electrocuting Ivy's body and returning her heart pulse, much to the surprise of both women, but the hope was quickly dampened when her body lit on fire from the electrical currents. Mitzi leaves to get a fire extinguisher, leaving Susan alone with Joe who regained consciousness and confronted her with his fire axe, presumably killing her. Joe takes off with Ivy's corpse, leaving the machine on and causing the building to set on fire with no further mention of Susan.
Ending B, The Impossible Edit
After knocking Joe unconscious, Mitzi arrives looking for Susan. After a short coversation, Mitzi leaves to call the police but Ivy's pulse returns, much to Susan's surprise who calls for Mitzi to get ambulance but Mitzi had already left. Susan begins to exit the lab when Ivy suddenly plants Joe's fire axe into Susan's back, killing her and taking off with Joe after starting up the resuscitation machine, causing the building to catch fire.
It is evident that Susan had not yet lost immortality after her ordeal in The Cat Lady when she turns out to be one of few survivors in the building fire and required absolutely no medical treatment.
Ending C, The Sixth Parasite Edit
Noting that Joe is still breathing, Susan straps Joe to the electric chair and begins electrocuting him to death. She proceeds to return to her flat and use Mitzi's former laptop to advocate death to suicidal persons seeking help and comfort, suggesting Mitzi succumbed to her cancer. In her flat is a shelf with a collection of trophies from her previous parasite victims, such as a hand-crafted mace that she used to kill Doctor X. Her latest trophy is Joe and Ivy's wedding rings.
- Susan is the English spelling of Susanna, meaning lily. This could be in reference to Susan's love of flowers, and/or the fact that lilies are the cause of her daughter's death.
- Her surname, Ashworth, could be in reference to how Susan values herself due to her depression.
