Yup even I don't feel that she is here to hurt lakhan / poonam or anyone ...I feel she is here to take revenge on dadaji for what he did with bindiya . I feel the card incident isn't of cheerharan day but before the Phere scene , when they were coming from jheel...might be at that time dada send goons to kill laakham as poonam a minute before was fighting with him and he showed her gun too and that's when komal saved them and then uchalo keechad at him and finally landed in the house with her rahasyamai baksa . I don't feel she is against lakham , her smile while watching them was genuine , nor I feel she was responsible for fan fall because after lakham went , she wasn't giving evil smile or something , balki was suspicious ki gira kaise honga , she was even suspicious that why was poonam sleeping there and not with her husband . I don't feel komal was behind fan fall .
