I have a problem with the whole Holi episode. Agreed Sonal was threatened, but to hire evil personified to kill R was a bit much. Also to have R gyrating away with a high KT while the entire Garg family watched with pride was a little nonsensical. Finally when R accused KT the fact that Mayank did not protect his sister was a little strange (but they never developed his character so it's never clear how he will behave!).
I guess we have to allow some poetic license or else the show will go off the air. Got to please all those who are watching to escape their lives, rather than to relate to their lives.
