Haha! What a fun post! Its a one-pot meal. Can sometimes be flushed down the other pot as well.
Also:
1. Adopted kid (who doesnt know it yet)
2. Najayaz kid
3. Dad having extramarital affair
4. Ayyash + characterless bhai/behen (Rohan/Pari)
5. Blast from the past = exes
6. Amnesia/coma track
7. Ageless 100 yr old Dadi who is fit as a fiddle
8. One useless relative/ex who turns blackmailer as and when opportunity arises
9. One random phuski bomb but overhyped raaz. Which when revealed you are always disappointed.
10. One sane person on both sides, whom no one listens to: Ajit for Rohit and Netra for Sona. If only Ro-So took their advice seriously, adhi problem solve ho jati.
