Because she knows he has advised pri many times but pri kabhi Sunta nhi...he told him have a fresh start when he came back, he didn't listen and uske baad kya kiya we all know (hina said him hum badla lene whereas Vikas said bus kr)
Uska and Ben ka relationship,,vikas told him not to be so close to ben and ye bahar galat dikhega but they didn't listen (and Ben was divya s main problem...divya lectured pri in that topic...)
Ben ke kapdo pe comment wala issue...usme tabhi bhi bola tha aram se baat kro and dono galat hai still pri didn't listen...
Vikas told pri not to sacrifice his hair because he has shoot (but fair enough ye uska decision hai uske balo ke sath Jo Krna hai)
And whenever pri cries he goes to vikas to cry... she knows he ll be there to handle him at that time when he would break down and cry
And Vikas and Priyank were always her fav but ab pri nhi hai obviously...ya maybe show me ayegi to ho jayega...
