* AmbiguouslyEvil: She TookALevelInJerkass and constantly threatens Norman, but she's entirely right in questioning his sanity, making her character ambiguous.
* {{Archenemy}}: She's Norman's greatest enemy.
* ArmorPiercingQuestion: She constantly delivers several of these towards the town sheriff and her daughter about Norman.
* AssholeVictim: [[spoiler:In ''Psycho II'', her [[HeroAntagonist actions]] in the sequel before her death might have been [[WellIntentionedExtremist good intentioned in a way]], but otherwise still [[HeWhoFightsMonsters amoral and vindictive]] towards a man who paid his debt to society.]]

* FaceHeelTurn: She was originally the hero of the first film, but the sequel has her become the antagonist trying to ruin Norman's life out of spite.

* TheHero: In the first film only. Unfortunately, she becomes a villain in the sequel.

* NoSympathy: She doesn't care that Norman has truly ''reformed'' and intends to have him recommitted anyway.
* NotSoDifferent:
** Seeing as how [[spoiler:Lila treats her daughter in ''Psycho II'', she has more than a few similarities to the mother that drove Norman Bates insane.]]
** And, of course, there's the fact that [[spoiler:she sets everything up to make Norman go insane again. Sure, she has a reason for not liking him because he killed her sister and several other people, but to attempt to send him back to the asylum and possibly kill again is just ''wrong''.]]
* OhCrap: Has this reaction upon discovering what's in Norman's basement.

* TemptingFate: She constantly says that Norman is a psychopath who hasn't changed. [[spoiler: She's proven right in the end after her revenge had a part in driving Norman back into evil.]]
* TookALevelInJerkass: In ''Psycho II''. In the first movie, she was a polite but determined woman who wanted to find out what happened to her sister. In Psycho II she tries to [[spoiler: amorally drive Norman insane again out of revenge.]]
* UnknownRival: [[spoiler: Norman has no idea that she's attempting to ruin his life. Simultaneously, she has her own unknown rival stalking her for trying to harm Norman.]]
* [[VigilanteMan Vigilante Woman]]: In ''Psycho II'', when [[spoiler: she decides to take the law to her own hands to apprehend Norman herself]] after feeling the courts "protect criminals, not their victims," when Norman was released and declared sane.
* WellIntentionedExtremist: In ''Psycho II''. Aside from the fact that her attempts to [[spoiler: drive Norman insane again to get him recommitted are a result of avenging her sister's death]], it also seems out of protecting any other potential victims (or as she quotes them to be "an innocent public") out of harm's way of a "homicidal maniac" (also quoted by her in the opening courtroom scene) in case if he ever relapsed back into insanity on his own [[spoiler: without any interference from outside parties such as herself]] if not sooner. Plus, even though Lila [[spoiler: did not seem to care if others who are already killed to have their deaths pinned on Norman anyway, it could be possible Lila saw them as necessary {{Sacrificial Lamb}}s to bring, what she see it as, a KarmaHoudini murderer to justice]].
* WidowWoman: In ''Psycho II'', where it's revealed Sam Loomis, whom she married after the events of the first film, has died before the events of the second film.
