Arjuns comebac is very much needed now i believe !!..Its only her brother who can instill that faith n courage in her...she Had seen her brother disowning his love ...Its the same brother who will cry his heart out that wat sin he had commited in renouncing his love n that has been the worst descion of his life...He will be back to support his suster saying that what he has committed she will not repeat it...She shoulld stand by her love !!..Nainas eyes ned to be opened n thats her brother who would guide her...He never liked Sameer earlier but now loosing his love shefali forever ...he will very understand Nainas pain...Samainas love!! n will give her the final push to stand up n not be coward like him!! I guess this CLOSURE IS NEEDED now when Arjun will reveal all his wrongdoings against Sam n will be the full supporter of Samaina!
