99.9% its clear that Sid is pretending as Raghu..we don't know the backstory of Raghu..and what is the connection b/w Raghu and Sid ..😲even if cvs give a proper explanation for him to pretend as raghu and staying away from his family specially roshni or they may give some lame excuse for it..
i wont bother much about it or would get angry at him, in the same way i didn't bother about Roshni asking some stranger Raghu look alike of sid(at-least to her) to act as Sid in front of whole world and pretending to Kiss him/romancing him ..and totally forgetting about MMS issue even after shabby taunting RaSi about it😆..
I know both things are not same but still ,i think both of them can avoid doing these things and can plan some other things whatever is their motive...Sid is lying to everyone and Roshni is also doing same 😉..if Sid is wrong so is Roshni...its just my POV😛
