Larry Harvey has been one of the most enigmatic and mysterious characters on 'American Horror Story' (Wed., 10PM ET on FX). He isn't a ghost haunting Murder House, nor was his relation to it completely clear, until this week.
In fact, we gained a greater understanding of why Constance moved next door and has stayed so close to the house. We learned that Tate was her son, and we know that he haunts those halls. But she has a far more grotesque son she used to keep locked in the attic whose spirit lingers as well.
