Always Doubted Dubey ...

Very first reason being Prashant dying at the hands of Yash ... unintentionally yes but Dubey being the sole supporter of Prashant, and seeing how everyone from Shobha to Aarti to Ansh always praised and did Yash jaap to show Prashant down made Dubey more resentful of Yash ... and this was always shown from the time Prashant came back ... Shobha especially went to all extremes to show Prashant down in front of Yash .. even after his death she didn't attend his funeral!!

So .. expectedly ... if Dubey's resentment was already at an all time high .. the death of Prashant .. and the fact that Yash was never accused or taken to jail for it .. was something that must've made Dubey's blood boil .. his only son was taken away .. and now that Ansh is his only blood left .. he wants him back ... yes he chose the wrongest way to go about it .. didn't ever confront Yash or Aarti about it .. but I guess he was a grieving father and his son's death took a toll on him ...

He seemed like the only member of the family who didn't care much for the fact that Aarti and Yash were separating, etc .. and seeing that behaviour I always knew that he is the one who is up to something ... him being unphased by all the events was the biggest clue .. and well it turned out to be true today .. so I'm glad my doubts are positive ...
