how exactly did radha got the pictures...either akaash stole the pictures when he came to work in the mansion, or she used to sneak into the house at certain times and stole the pictures...arti has to go and find the frame that prateik gave her and see if it is missing...the same set of pictures on the frame are in the house...i don't thinj that there were a lot of duplicate pictures of yash laying around the mansion...so someone stole the set of pictures from the frame that is one way...mystery of mysteries...sp must know if he had a relationship with the woman...only if he was drugged and of course as we all know all dna test in serials have so far been rigged...to make yash not sp son will put the show in a real limbo...
