They better reveal it to Rahul ASAP ( read this week ) . Cos we to know it already to separately nhi bhi denge to chalega. So it better be this week itself.
This may happen this week on Friday only so that they can leave us at a cliffhanger. Are we know but audience without spoilers don't so it may happen separately too bit most likely one pair will discuss it and Rahul will overhear it. We know very much till now that overhearing is one of the favorite pastime of this house members 😆
