Was w/o internet since Thursday night, so couldn't comment until now.
First of all, this was a great episode - and here's why. Finally, Raghav tells Tashu & Komal what they needed to know about Viraj. All these months since Sia moved into Raghav's home, showing this info being suppressed just made it insufferable - Friday's episode felt like really letting it out. Had they known about it, Komal could have taken precautions so that Krish didn't get victimized by Viraj, while Tashu too could have avoided being drugged by Viraj even once. Speaking of which, as I noted earlier, this track of trying to drug Tashu and then make a po*n video (incidentally, what does MMS stand for here?) was really inane.
Okay, about the rest of the episode - I really loved Raghav's moment w/ - not Sia, for whom my disdain hasn't disappeared - but w/ Komal & Tashu. I liked him explain to them how he didn't want Sia to make a forced decision, even though this highlighted that both of them were prepared to welcome her into the family.
The sangeet for Raghav/Sia was beautiful, and the funniest thing after that was when Viraj was doing his metrosexual dance, and this time, instead of Sia or Raghav, it was Gayatri who caught him doing that - was hilarious, as mystic pointed out.
Unniyal was either faking w/ Raghav, or w/ Viraj. Guess we will find out tomorrow.
