His eyes also look similar to the guy who called saying kusum to get out of Sarla's house.
Nitin and Ajay mama are the 2 people who could use this phrase.
Nitin may have killed mahi accidently thinking it is kusum.
- He may be doing that because Abhay was planning on giving his property to kusum
- He loves his granddaughter kali and he also thinks all this is happening because of kusum
- To keep his family together. i.e is abhay wont be running behind her anymore
And it is also said that killer might be one of the house members.
He is one of the members who is least expected to kill kusum or anyone else.
This is my thoughts.What do you guys think?
