Whatever happens in the last episode, Desai has already won. His aim was to enjoy Meera and he had already accomplished that. 
  He has already shown the state of Krish's facade marriage, Meera has no trust in Krish, but trusts Desai unquestionably.
Even if Meera comes to know about Desai, no way will she be able to go back to Krish after what she put Krish through in the last episode. It is a win-win situation for Desai. If Meera breaks up with Desai then Desai will make sure to destroy Krish financially.
Tejas' wedding reception may be the climax of the story.

No man..he really wants Meera if not he wouldn't have gone into so much effort to feed into Meera's brain about him being a great person..Initially all he wanted was to get into her pants one more time but he started to understand that she is perfect for him in all aspects. His win will only be after he gets her else its a lost battle...he cannot take Meera's hatred for him, that will break him.
