Maura talks to herself from time to time, having full conversations and debates. While she never blames her actions on anyone else, she does exhibit signs of a disassociative personality. When she first sees Deep her expression is one of curiosity though her action is to ensnare Deep, intending on eating him but loosing her will do so when he mentions having friends. With her own loneliness being felt she retreats to her tire home and begins talking to herself in a debate over food for her hunger or friends for her loneliness. The dialogue she's having is mildly backgrounded with focus on Deep and his friends but she convinces herself to settle her feelings of loneliness rather than hunger. Having previously stated that she doesn't like knowing the names of those she eats she introduces herself and gets their names as a show of her intention to socialize. The personality she expresses during this early interaction is jestful, and friendly. In her sleep she ingests first Evo, whom she said she had no interest in eating, than Deep, and finally Alice whose clawing at her throat wakes her up. It's unclear if she was actually asleep, or the scene is meant to express a more concerning situation of 'DPD with Amnesia' as she's instantly upon waking up distraught at having swallowed her new friends. While saying she's never had friends, she admits to having had experience with this situation of sleep eating by telling Evo, Deep, and Alice what usually works in getting her to calm down enough to bring them back up her throat.Assuming she does in fact have an alternate personality it would have first materialized on screen during her tire talk dispute over weather to eat Deep or befriend him. The second manifestation of this personality would have been as the crabs came around with hostile intent. The third manifestation would have been at the City of Man where believing Alice to be correct, that she ate a Human baby, Maura snaps at Alice with hostility at her suggesting such out loud. Her personality in this moment is more tactful, distrusting, defensive, and despite concern she's shown over eating people before- is not at all apologetic for the (incorrect but at time believed correct) realization of what she's done. This personality focuses primarily on self survival with little regard for others. Continuing this assumption the personality's control in that moment is broken when Deep unexpectedly apologizes on Maura's behalf. This would be the last time in the film that said personality manifests. With the potential other personality being one designed to keep her fed and safe it implies that her DPD is caused by trauma and that such would have involved past associations being destroyed by her and an inability to reconcile what she did in the past. Her statement that friends don't eat friends but she never had friends and condition where in she eats in her sleep could indicate what that trauma is and why she was afraid when it seemed to be happening again.There is also the possibility that she has a third personality that isn't defensive but playfully predatory- and that such was the one Deep first encountered. Said third personality would be a vague reconciliation of the two others that while predatory is 'nice' about it and tries to make the situation 'fun' or otherwise pretend that what she's doing isn't horrific. The fun aspect accounting for her being somewhat seductive where her other more amiable jesting self is a bit aloof to romance at all. "Hm...hi." She is a blue moray eel with yellowish eyes, sharp teeth, and a small mole on her face.
