Hive account@adsactly: I'm curious to know - why name this story 'the tainted chalice' and what does the red rose symbolise in the story?

I'm really not able to connect he story of a vengeful pregnant woman who ends up killing 3 people in addition to her cheating husband with that of either a chalice or a rose - sorry, I'm a little blank here :)

PS: I'm really suprised half the coments are on the beauty of a rose etc etc instead of the actual story too. The story was captivating nonetheless.
