Brother or husband?

Rating: Null/10 (28 November 2003)

The character of the mental patient - does anyone else think that he might have been intended (at some point in the writing of the script) to be her husband, & not her brother? It seems to make so much more sense that way. She calls him "Babe" & "Darling". Also, why else would she have delayed putting a move on her handsome co-worker for so long, & seem so conflicted about it?
Just wondering if anybody else picked up on that.
