What the mom thinks about the change (use genitives):

Ali’s change has changed Parvez’ thoughts about Ali. I can see the changes, but I still think that Ali’s grades are good and that he’s a wonderful and clever kid, so I don’t understand Parvez’ concerns. I think that its consequences could be that Ali’s and Parvez’ relationship will be weaker, so I’m worried about Ali’s and Parvez’ relationship.
