Dec 9th
Garv gives an excuse and goes away. Rimjhim takes Avinash with her and follows Garv's car. Garv reaches to the hospital for DNA test. Rimjhim suggests disclosing the truth, but Avinash wants to talk to doctor in this regard and marches to the cabin. Rimjhim feels herself guilty and her conscience tells to inform Garv. There is a sigh of relief on Garv's place when Doctor says that the report is negative. Garv says sorry to Rimjhim and repents on his deed. Rimjhim discloses that the DNA report is false and Garv is the father of Vivek.
