Well, the therapist aims a gun at Nicholas at the end of LSFNY. Maybe he considered becoming the rapist and reconnect with Victoria
, but decided against it for some reason. The question is if we can be sure the gunshot was lethal. It might have critically wounded Nicholas, maybe there was a coma and some memory loss, but he may have survived. And Nicholas who used to be called Nikki by his childhood friends slowly wakes up in a hospital bed, drug cocktail induced delusional state, machines beeping, "Dr. Blair, Dr. Blair, Dr. J. Hamilton, Dr. J. Hamilton", and his first words are: "I remember now, I remember how it started, I can't remember yesterday, I just remember doing what they told me..."
Maybe we'll never know.
Greetings...
