You're working as a nurse in a mental hospital. Despite what Hollywood has you believe it's not a very hard job. Most patients are timid and very calm. Some of it is because of the drugs they're on and some of it is because they're not crazy people. They're just some poor and unlucky people with some mental disorders and they're seeking help. It's actually a very rewarding job to help this people overcome their illnesses.
The sector you work in doesn't have many issues. There are some people with dementia, some with psychosis and a whole ton of other problems. They're mostly normal, at least compared to one of the main and most problematic people in the sector. Her patient number is 58006, but her name depends on who currently has her brain. There's a very unsettling one named "Luna" and there's more kind and helpful one named "Lara". Simply by talking to her you can understand which one has taken over currently.
One night, when your shift was about to end, she came to you and asked for a council. Everyone was either gone or leaving for the day, but you decided to remain for a few more minutes. so you unlock your office's door and let her in. Then you offer her a sit and when you were headed for your sit at the other side of the table, a sharp pain in your neck caught you off guard. You quickly turn around and see her grinning from ear to ear holding a syringe in her hand.
