that was my exact thought

Intresting. I didnt give the "serial killer answer".

Its funny how TM875 and slant eyes stated that the "serial killer answer" is obvious. When its not. Many answers can be given.

She could have been a killer herself.
Her sister might have stolen the man.
Could have found out her sister killed her mother.
etc...

All of them having some for of logic behind them. Therefore the answer given at the end is not obvious at all. This is more like an inkblot test.

didn't get it, had to scroll down

I didn't get it either -- guess I'm safe for now. Not funny, but entertaining!

hmmm, maybe there is something wrong with me then. be scared, be very scared.

I think like a psychopath... but I want to be your friend Jadzia!! :)
