My guess has to be SHARK, maybe even now they r playing games where they are one who killed PS and planted doubt in Sid mind ,misleading him by giving him all clues and proofs so he slowly destroys KK given he is vulnerable without PS. So once Sid destroys KK , SHARK will eventually gain upper hand and something much bigger.
Isn't this the whole plot, Sid journey all about self discovery where he will make mistakes owing to his over confidence then fall down big time , then again rises from ashes like Phoenix to fight and protect his own people.
My guess anu might Mis understand him initially but later will put two and two and realize this was the reason for him to push her away so she doesn't have to choose between Sid and KK when truth is out and then help him and guide him in this resurrection and bring truth out.
