Devi's concern in today's episode had many layers within it.
She is actually worried about Devi Tai and if Sai will get Devi Tai married to Pulkit who is a wrong guy as per Kaku/ghar ke bade.
She is a very complex character, I agree that she did it to win against Sai. But, she did believe in the Kaku's version of the truth and really believes that Pulkit is not a good guy for Devi. The letter was planted not only as a fight against Sai, it was also the only way, she knew Virat will oppose their marriage.
You know, deep within her, there is a person who knows what is right, she acts as per that. It comes out unknowingly. However, her jealousy towards Sai overshadows this thought/ trait within her and that makes her behave like the vile Pakhi we all see. She gets carried away, suppresses her morals and turns into a manipulating character.
The main reason for her concern
Her concern for Devi Tai is like a key to Virat's head. She can get into his head, put thoughts into his against Sai, only if he starts to think Pakhi cares for Devi Tai. She knows how to play with his emotions very well. Disgusting character.
