As per history, The poisoning thing was actually Chanakya's plan. He suspected attempts being made on his life and poisoning was an easy way to kill so he used to sneak in small survivable doses in his food without his knowledge and increased it with time to boost his immunity.
Durdhara died because Chandragupta unknowingly fed her from his plate and the amount of poison in the food was sustainable for him but fatal for a non-immune person, which killed her. Chanakya ripped Bindusara from her womb before poison reached it so that atleast one survives.This was later used by Chanakya's rivals in Bindusara's reign to turn him against Chanakya, portraying him as Durdhara's murderer, but that's a different story.In this scenario they may show Nandini initially making attempts to kill CGM, which may have incited Chanakya to do that. We all know that it's been established in the promos that Nandini married CGM to kill him.Durdhara's unnecessary death could be a reason she has a change of heart, thinking war etc. never did good for anyone.Just a guess from my end, but it would be a good potential track.
