I was talking to my daughter-in-law last night after the episode and we both thought Ram was the obvious suspect but will it be the obvious one? In her interview with Cassie the lady who previously backed out of her top job offer was so dispassionate it could be her, she has a pretty miserable home life but she is planning a wedding, perhaps she doesn’t want her future spouse to know about her past. Then again one of them could have hired a hit man, the rich one possibly, he does have some dubious connections.
On another point, if something has been aired and I haven't watched it I don’t look at discussions about it until I have. The definition of a spoiler seems to be changing from not discussing anything that hasn’t yet been broadcast to not discussing anything at all in case somebody hasn’t watched it yet which is odd.
