They are starting on
1) VK murder investigation2) Shivi tantrum
3) Sara’s family returning
4) Pri’s friendship with the investigator
after the second kangan is given. They will finish with C & C before all these. If not, consummation will happen only after the resolve the above.
Point 2-4 are not big deal and can be dealt within 7-10 episodes which are enough time, for Priya to realise and confess her feelings to herself.
VK investigation is a long track which will go one for 4-6 weeks minimum, and Raya are not directly related to that kand so it won't affect C&C.
