The paper cutter scene!!

Do you guyz think it was necessary to show something like this......Geet suspecting Maan's intentions & keeping a paper cutter at hand to ward him off..????seemed too far fetched..He didn't take advantage of her when she was all alone with him in Hoshiarpore as well as after the party ...then why would he attempt something like that now??? either Geet has gone mad or the CVs!!!
