deepali will store some kind of evidence of this vomit inducing interaction between her and rk for future use(for example show it to madhu or blackmail rk).
according to the TC article...madhu will probably not witness this horror show but may come to know about it later.i would hate it personally if deepali suceeds in taking rk 'all the way'...it would be a real damper on madhu/rk intimate scenes if there are ever any in the future.
