For those unfamiliar with Alice's body of work, the name Steven here can hardly be a coincidental choice. On the Welcome to my Nightmare album, there is a trilogy of songs telling the story of a man severely afflicted with mental issues, one of which was a split personality and childhood regression. By the end of the story, in a psychotic break, he ends up killing or severely injuring his wife. The name of the child personality? Steven.
The full story is much more interesting and more chillingly rendered than the very brief description I gave here, and was done as a video presentation in the 70s with Vincent Price. It's great stuff, and I'd be very interested to know if this Steven is the same character as presented in Welcome to My Nightmare. If so, it could be less "simplistic" in context with the larger story of the Steven character and tell more about him that wasn't previously known.
