disagree cause thats not arohi...if she wasnt there and arjun had confessed to it she would have been against him and supported her family she has always sided the truth be it gauri,rashi,raj or any other matter so her statement is valid since both are equal in her eyes and she wont do nainsafi to anyone and will side with the truth so if shes saying she was with arjun people have to agree no other option...
