As you would all remember, when naira survived the accident she was stumbling around in the jungle and became unconscious. Seeing as this track is such a typically crappy ITV serial track, they could have at least taken a differen route if doing a typical ITV serial track for ratings is what they wanted.
They could have showed that she lost her memory when she finally woke up, was found by someone or even a new guy who took her to the hospital to treat her injuries, the doctor tell the person who found her that she is pregnant, but as naira has lost her memory she does not remember about her pregnancy or the father of her child. The new guy adopts her (hehehe) and tells her he is her husband and the father of her child. Naira believes it and karthik and family all think naira is dead. This way the writers could still show the whole everyone-thinking-naira-is-dead, karthik-remarriage, karthik not knowing he has a son track, but at least naira wouldn't be so hated and neither would karthik or naira's characters be ruined or made to act stupidly. This track is literally just like the previous separation but worse because they actually made naira look bad.
