We don't even know who is Shiv exactly. And, as everybody knows Namik is very Sanskaari & on sabras radio 2016, he clearly mentioned that he wasn't comfortable with casting couch. I don't think Namik did anything asanskaari in yesterday's epi. Sharanya was feeling an image that was in her subconscious state of mind & her fears were very much visible on her Face. She felt as if somebody was coming near her to kill as Odhini mentioned that Saaya will not leave her. That could be the main reason for her Mind and Heart being tormented.
One Namik + One Woman = Fevicol person & I don't think he would accept doing something uncomfortable😊
