Jeesa had an affair as i had said in my earlier post and urvashi is from tht affair..and then she handled her father's business..No.1 she is psycho ther's no doubt abt it..No.2..she had done fraud in business..(we all tht she is a miser).No.3..she had a crush on Brijesh since young age..Rem.Tara and Brijesh's not arranged marriage...No.4..she is a demanding, arrogant, manipulator kind of person..so she had done physical harm or accident which jeesa is the witness and he may had given the compensation or used his money power to closed the file..No.5..urvashi got pregnant before marriage....No.6..she was forced by jeesa to marry Rajshekhar...No.7..Seeing Tara always getting the best of life create an anger,jealousy,hatred in her and she knows tht Tara is not her real sister(step-sister)so she has taken this step to get rid of her and also she will get the property and most important BRIJESH (her childhood crush)..these are the reasons..
