Why and when vansh came back

What happened I want to know a brief as I stopped watching after pati got out of their clutches

goons killed  ankur -Ankita (sandhya's bhai-bhabi, vansh's step parents) vansh saw them getting killed so he came to pushkar to inform sandhya and sooraj .. they forved him to stay back at rathi house but he didnt want to stay caz he hates sooraj sandhya he thinks that sooraj sandhya left him caz they dont like him and treat him as their son as they do Ved so as soon as he came out to leave from rathi house the terrorist attacked the hanuman gali and so he culdnt leave and he is here with sooraj and sandhya .. hope that helped
