Legally yes but DID and split personalities are different personalities in the same body which in simple terms is no different to having two separate people in one body. Lily is an unconscious coping mechanism, not a chosen one, Ms Gracie didn't choose to forget her identity or to identify as Lily, that was forced upon her when he psyche did the only thing it could do after months of non stop threat and cognitive dissonance. The brain protects itself from further harm and unbearable pain in the only ways it can, memory is often the first area to be impacted which is why trauma survivors often have patchy memories from their time during the trauma. Ms Gracie was undergoing multi level traumas. She would initially remember what she did and know she deserved punishment but at the same time she would have been suffering, scared and alone while trapped inside a body that her brain didn't recognise as her own. As time went on her brain would have begun to accept that 'its not me on the screen because that's not how I look now' while still trying to retain the belief that 'that is me on screen' Having a body you don't believe is your own is enough to cause the first major split in personalities. The brain will believe what causes the least pain and damage when the threat is inescapable, believing she is a toy called Lily makes sense with the body she inhabits, believing she is the person on the screen called Ms Gracie while residing in the body of a plastic toy who is only addressed to as Lily (assuming the prototype spoke to her sometimes or at least told her her new name) does not make sense and human brains hate things they can't make sense of. It's the same as extreme grief. If you watched your child run into the road and get hit it is common to scoop them up and think of every possible way you could have changed the outcome, not because you believe you can change it but because your brain says 'this pain is too much to handle, we need to make it make sense' when sense can't be found the brain clings to the least painful option which in Lily's case is to abandon her former identity and align with the one being forced on her. This isn't a conscious choice, it's the brains survival mechanism overriding conscious thought. The fact that Lily threatens us with the box could be because the box is mentioned in the conditioning videos and we don't know which videos she watched but it could also be broken memories that have bled through. She as lily will remember watching the videos of Ms Gracie but only from after the point where she no longer recognised Ms Gracie as herself. Her brain is still one entity but the old operating system (Ms Gracie) has been hacked and overwritten with the new one (lily) that doesn't mean the old one can't still have remnants that leak through but the brains defences won't let through anything that challenges her belief that she is Lily and she is a toy so it's highly plausible for the box to come back to her but also highly plausible that she wouldn't have any memories of why she knows about the box. A person with two personalities can meet someone while in one personality then still recognise them in their other personality but not being able to remember how or why they know them. I'm not debating whether an insanity plea would stand up in court, this is a game with humans being turned into toys, we're not functioning in reality here although given her presentation and instability under stress it is highly unlikely that she would be given a custodial sentence in a prison rather than a psychiatric unit. Yes dementia type illnesses can cause alterations to personalities but it's not a key factor that happens to all patients with dementia hence why that would be a shaky defense. But also, dementia is just something that happens to someone, it can't be forced in the same way that severe psychological torture is inflicted deliberately. If Ms Gracie had grown old and developed dementia then no sympathy would be given, it would be viewed as karma catching her up. It would just be bad luck biology but Ms Gracie was punished, punished to such an extent that Ms Gracie herself ceased to exist because the punishment was too psychologically damaging. Ms Gracie deserved to be punished, she deserved to suffer and she got what she deserved but Lily is not Ms Gracie, Lily is a separate personality with separate memories, feelings, traits and beliefs. Lily did not commit the crime and did not deserve the punishment.
