Dont know why, but watching todays episode, it seems to me that all this is again Rishab's game to separate Rahul and Priyanka.
The way he tells Priyanka that her relationship with Rahul is attoot, and he sort of blackmails her into puting her relationship with Rahul aside and help in sorting out his problems.
By what he is doing he is getting everyone's love and sympathy back again.
He approved Rahul's project, this way he will not have to give up his position as president of LGI.
He told Priyanka he wants to adopt, maybe he is thinking of Tanya's kid, as Tanya is i think still locked away somewhere by him and Ronnie.
Speaking of Ronnie, still no news after Kunal beat him and sent him to the hospital.
I feel he has some plan behind all this.
