who is this vampire leaking ranaji's blood?

i read the written episode. so disgusting. brother and sister both are psychopath. today i was thinking all of a sudden if they brought surbhi joti as ranaji's sister(positive role) it would have been so nice. she would have looked perfect rajmata's daughter. tall like her. no offense. i am sure rajeshwari will do well. i don't know why the writer gave her negative role.i don't know this actor. about subhi joti, i really like her. to bad she is still in QH. enjoy the track folks!
