Sid saw the key of Rajveer car and his car couldn't go to service due to the car absence and then sid noticed some movements during his visit to Baweja house so I think when Sid will reach his house Simran will blast on him and someway Rajveers absence will also come in front which Sid will catch and got the hint
also Roshni heared Rajveer half convo with Baweja and what I remembered she did heared Baweja name so I think she will also tell this to sid and both will find out about rajveers involvement
what do you guys think?
