it's definately not EKU, but i don't think it will be even mayank. if u remenber after kt and lakshya got engaged. kt started receiving some treats like somebody was roaming around her room and than somebody threw stone and letter in her room through window. i think it's same person who was scaring her. it can't be mayank scaring kt. either it's manthan or somebody unknown sent by bhoomi or mandira or may be sent by lawyer in jail. i think it's definetly manthan. i jave just read update for 6th, not seen episode yet. so don't know how does person looks frm behind. i might be wrong too. let's see wht happens.byt ekta has really gone crazy..........she should have shown things getting better but it's getting worst everyday. she has opened everybody's life chapter and kept it incomplete. their are so many stories going around in one family. nand-karan-tanya. ganga-sahil-and family, bhoomi-mandira, eku-laks-kt, raj bhasim-his son-bhomi, don't know where is nandini and karan's son. their are so many dushman's anybody can make an entry anytime in ekta's serial.................
