To give you a brief update: Armaan and Jassi adopt the child, Vedika, but the adoption agency says they must also advertise for the child's biological father. Aryan sees the ad and comes back to claim the child. The adoption agency is bound to give him Vedika. Aryan bargains with JandA (Jassi and Armaan) to give him Gulmohur if they want Vedika back. JandA manage to tape Vedika saying that she is unhappy with Aryan, so this can be used as evidence that Aryan is not a suitable father. Aryan comes right then and snatches the child and runs with her. Armaan gives him Gulmohur's papers and gets back Vedika. Aryan is so happy to see the papers that he steps backwards (he is standing on a terrace), falls, and dies. Before dying he repents of his misdeeds and asks JAdnA to look after his daughter.
You can also watch the videos of these episodes. I think there is a video archive of January-April 2006 vidoes on this forum...you'll have to search for it though! 😊
