Good old Melanie "A murderers best friend"
Anybody else find it interesting that her pool of friends consist of people who are either dead or going to be in short order? Methinks Melanie has serious intimacy issues! 
You know, of course everybody needs friends.
And offering the hand of friendship is mandated by God.
However, I don't think Melanie's hand is what such people need; there's others more mature, more stable, more unselfish and disinterested, more effective, who could do such people more good during their last days of life.
If I were a murderer, I'd sweat and cringe, if I knew my stoutest friend was a deeply-troubled, probably psychotic, undeniably hysterical, primitive.
I'd be sweating clams if I was leaving life, knowing this was the only "friend" I had.
It's obvious Melanie's into this thing merely for her own ego-gratification, and not for some unselfish purpose.
