I am sure Varsha will not tell to ArMan that this is your soham...and somehow I felt from soham's reaction was not caring for his mom when his leader mentions about his mom's call...so how ArMan will recognize him...
may be the story line will be...vishnu gets hurt by police and Manav thinks vishnu got hurt innocently and gets him home...and vishnu will change because of everyone's love towards him in deshmukh family...then ArMan see the soham's birth mark then the truth will be out...
I know one of the email thread says vishnu is not soham, but still i feel CV's doesn't have to bring-up new villain character as the show already has so many villains and they did not close any villain's story till now...
