Arjan should never come back in anyway. Its true he had a tough life being poor but he had parents who seemed to love him and as a boy of the house he had responsibilities to look after them he accepted his foster parents as his parents, even if they were poor. Santu had no parents but was raised by her poor elderly nanaji so it just depends on the person and how they take life. Even before Moulik instigated anything in the whole Arjan situation, this Arjan guy was misbehaving with his wife, by slapping her and beating her suspecting her of still having a relationship with Hiten. He got greedy as soon as he realised he was a Mahiyavanshi, it got to a point he did not want Santu to have any kids, who is he to decide what Santu and his dad should and should not do and whether to have any children 😡 it was Moulik after seeing all this decided to make more trouble and set off Arjan to do worse. Plz never bring this loser back on to the TV to haunt us or SANRAJ, he is the reason SANRAJ were separated for 10 & half years. Birwa saved her dad, she was a kid, did not think before acting and she stabbed Arjan to save her father from being murdered by her lunatic brother.
