Well, someone suggested that Nihal could be Veera's father and from today's episode its evident that Veera does have some bond with Nihal with the way she kept smiling at him and watched him leave...He did recognize Ranvi but didnt connect with him like he did with Veera today...
Nihal's identity is suspicious but in what way could he be related to Veera:
a)He can either be Amrita's brother...
b)Amrita's lover who didnt know Amrita was terminally ill and she wasnt aware of his one sided love ?
c)He can be Veera's dad and Sampooran ruined his own life to save him?
Though I like mysterious tracks, this one seems a little long and I dont think the truth of his identity will be revealed anytime soon...
