Okay I definitely think the accident is caused by aneesha...they have showed even in S2 as aksharas accident was caused by Karthik it was really believable now also they are showing something like that only...and everybody is gonna blame her and arohi is not gonna side her abhi is not gonna believe akshara and she is gonna be alone now .and also the reason I think aneesha has done this is she is gonna be hated by all goenkas especially Manish and dadi as because of her akshu has suffered perfect future plot for kaisha wedding track too
My gut feeling says its aneesha who did the accident and entire birla family is gonna be okay when they get to know this and case closed
