Dev is supposed to be in love with Radhika. Then how can he not give even a thought about what Radhika told him before leaving. Any sane person will try to connect the dots at least after Radhika went missing. He is supposed to be in deep love with Radhika but trusts only Barkha? Not even willing to look for proof ? Not even worried about her safety and well being? But runs home worried the moment he hears Barkha didnt reach home. He leaves his belated search for his wife and runs to grieve for Barkha. How absurd!! This behaviour is totally out of line for the Dev that we know so far.
On the other hand, Rohan seems to know and trust Radhika more than Dev ever did. Rohan is the only person who did not think Radhika is capable of doing what Barkha claimed, while the divine lover, dev readily accepted Barkha's story and doubted Radhika. What absurd story!!
