I knew that when they left Guddi's track in the middle that it's not going to get over until Atharva's return. Atharva has always been shown as her protector who has given justice to her in the past and this time he will be the only one who will give justice to Guddi and punish the murderer.
Now, I am not worried about other incomplete tracks either, because I know those tracks will get closure after Atharva will to come to know about everything.
P.s. Did anyone saw change of expression in Suman when Atharva was mentioning about Guddi?
