I don't think Tara's mother was mentally unstable, as you suggest. I'm sure she was an introverted, shy, gifted witch who was pushed from pillar to post by her family; forced into marrying the guy from hell and sentenced to a lifetime of misery. Her one shining hope would have been her little daughter who showed true talent.I'm sure there's a fic there somewhere. If only someone would write it.
