We are used to seeing something on promos and originally happening entirely the opposite in the serials. Sadhana's death occurred on a terrorist attack where she tries to save a small girl from picking up a teddy bear which she thinks was supposed to be fitted with a bomb. Her guess turn right and she dies in the blast while saving the girl.
Meanwhile, on the other side we see that Ragini has given birth to a baby girl and is in a very serious condition. Ranveer is very tensed and after hearing the happy news of becoming a father is sad about Ragini's condition. Guess this serial, as every daily soaps, is also going to take a leap of 20 years where we will see Ragini looking after both Sadhana's and her girl child and trying to balance her family life without her sister.
