The DNA report that SP was seen burning could it be Yash's done when he was a baby?
Radha switched the babies, but may be SP found out and switched them back and had a DNA test done on yash to make sure he was his son.
As far as AAkash is concerned, he may be someone else's son with Radha.
Radha may have had a score to settle with Sp for some other reason.
IT COULD HAVE HAPPENED THIS WAY!!!! Too far-fetched, I know.
WHAT DO YOU GUYS THINK?
