Never in an issue focus ur attention on one person. The moment v center our focus on one person we loose the insight of situation.
During this whole issue everyone just focussed on Ishwari, everybody was so overwhelmed with Ishwari's happiness that they lost insight to the situation.
Sonakshi is an educated and intelligent girl. But the moment Ishwari said she knows from vague symptoms that Sonakshi is pregnant, Sonakshi got so overwhelmed that she forgot the basics. She din bother to do a basic UPT and started celebrating. She lost the insight into a simple issue because instead of thinking about pregnancy, she just focussed on Ishwari's happiness.
Dev when came to know that Sonakshi is not pregnant, the moment he saw Ishwari pampering Sonakshi, he lost the contact with reality. He just forgot what a blatant lie he is speaking which has no basis or life.
When the truth is revealed everyone including he himself has been left so hurt.
After revealation also everyone is still focussed on Ishwari's pain and disappointment. They are again doing the same mistake. The result will be disastrous.
It is a big lesson. Whenever in a crisis look at the situation in totality and then take a decision. Or else u will fail miserably. Not let one person guide all ur decisions in life. Think about everyone involved in it and never forget urself beacuse in the end it's only u who is responsible for ur decisions.
Just a thought and point of view
