Btw I do think Saket knows everything. The way he stressed on EVERYTHING the 2nd time around... makes me feel he does know it. But knowing if he has kept quite then... i tell yeh ladka tho marega mere hath se...
I too have a feeling that Saket knows everything but wants Suki to come out with the truth. If he comes to know that Michi are on the verge of divorce I am sure he will let out the truth. But remember there has been no occasion where he either witnessed or heard anything about the problems Michi are having and why. In fact come to think of it I think they got Suki and Saket away from that party so that Saket does not witness Milsi-Baba show down and Prachi signing the divorce papers. I am sure Neev would not have discussed the issue of his being accused by Milsi with him in the interest of sparing him any worry. I also believe that Saket has high regards for Milsi and respects and cares for PRachi for after all she was instrumental in bringing him and Suki together. So he will spring to Prachi's defence if only he knew about the divorce (which I hope he would at the nth hour just as the divorce is ge4tting finalised).
