before pandey kidnap vedu she has come to know the truth..then she tries to call sahil..its after that pandey kidnaps vedu..So.I think the possibility is that ved had that shrutis pics and all na..maybe with that some other proofs like original dna report na saying sahil isnt father of nidhis child..puneesh changed it na..So that she might have seen but from nidhis intv looks like vedika came to know even more so maybe many other things eveidence she might have got by mistake with shrus pics..
