@Shaavi: Thanks! I think we may disagree slightly about the Dev-Golu relationship, but I am not entirely sure, so I will try to make it clearer where I stand at the moment. Dev is certainly aware that he is not Golu's father. He feels no responsibility towards Golu's upbringing, but participates insofar as it makes him feel good to do so. So I conjecture that his relationship with Golu is more for himself than for the kid. As I said in an earlier post, Dev is happiest as a nurturer and Golu fulfills that urge in him to take care of people.
I also think he feels a kinship with the child, since both of them are unwanted by their families, except for material purposes -- Dev as the accumulator of wealth, and Golu as its heir. Their relationship is not of the parent-child variety, but there is a genuine co-dependence there. I don't think it was a coincidence that Dev showed up at home just when Golu was due from school -- he was disturbed after his encounter with Sona and this is the first person he thought of coming to.
Dev being his new self, he doesn't want to betray how attached he actually is to this child, especially not to people who would use it to their advantage but I think he and Golu know that the attachment is there. And now, Vicky is getting an inkling as well. You might be right about him creating his own trading company (that would be a super-easy way to show him losing 500cr in a heartbeat), but I think he is much more likely to try and pull Dev back so he can do all the work. I think Golu will become a chip to play in that game.
But here is where I do think it will backfire. Taking away Golu will be taking away Dev's one source of emotional nourishment. If Vicky does this assuming Dev won't abandon his son, but Dev does, hiding his pain from the world, that leaves a ripe moment (story-wise) for Soha to enter his life. Vicky is forced to reckon with the fact that he alienated his son from Dev just as his true heir showed up on the scene. I think that would be really interesting
@Shaavi, Rekha, Payal: Very interesting discussions about how Soha's entry will affect Dev-Golu/Dev-Family's relationships. I am also curious to see how gender will play into this. Ishwari always defaulted to 'pota' when she talked about potential grandchildren, and GKB is definitely of the opinion that only men can be the scions of the house. It will be very interesting to see this issue come up as Dev will defnitely not see it in the same light. Ishwari's reaction when it comes to the issue of inheritance remains a bit fuzzy. She will definitely be over the moon at Dev's progeny, but will she stick to the idea that women are taken care of until marriage, and it is men who inherit wealth? Will Dev write everything off to Golu and walk away to be with his own family in the end?
