one thing is sure that the main one is still hiding behing the curtains, he is the person who is pulling everyone's string except RV & geetu... Whenever they are finding solution to one problem he throwing them into another problem...
2nd ly I think chotti Maa finally was realising her mistake but then she is killed... & killer is neither bhavani nor kalyani... RV definately not , he was also shocked seeing her dead (& now some will say that he did not react much, come on dont tell me that u expect him to thump his chest & cry..)
3rdly Kavya needs someone who can make her feel secure... She is too much insecured & vulnerable... & i think RV can definately do it... He can understand Kavya's mental situation & help her out...
4th Priyam , he from starting knew that chamki is geetu... he was waiting for right time.. when it cld benefit him... & he did it... & one thing i just remembere that in adaalat (sony tv) there was a episode in which a 10 yr old kid murdered a man... & in last it was reveled that actually he is 32 yrs old but he has some medical problem so he looks like a kid... This can be a case with priyam...
