I am sure Aditi will enter the show as some mentally sick(which she is) or physically sick person then only she can re-enter into chet's life by trying to get his sympathy.Chet being a nice person seeing her condition will bring her home and Anu being self-sacrificing and guillible might even accept this fate.Once aditi enters the house she will cause hovac in Anu's life in an effort to break Anu-Chet rishta and for this she has lot of people to support her too in that house.But what will happen in the end of two months for she will be only for two months hopefully.
