I don't see any thing abnormal here with Boses. i agree to most of the points against Elena. But she is not responsible for all the issues/sufferings that they had to face. If you ask me , it is Sona - her love , marriage with Dev was the reason for all the mess😃😆.But what to do everybody/we still want Devakshi...even after seeing these horrific and manipulative characters in that house.
Ok regarding the discussion - Even if the Boses were angry with Elena, will it be right to shout , fight or show indifference at that moment when a good and happy event is happening. This is how we behave aren't we? When we meet our loved ones the first thing comes is the relation that we have with them as daughter/son/mother etc. May be once the guests leave or after the important event /function for which they have all gathered gets over, they would react and discuss.
But again see how much they have welcomed her,their brain cells were not switched off...they were alert ...thats why Sona through her words and Bijoy through his action expressed that her visit was not a normal one once they hear her saying that she didnt want to miss her brother's special moment.
