i disagree that Lav and nitish shud elope- as first niteesh has already told TA that if he marries it will be with the permission of his father and VR or else he may remain without marriage.
why shud this happen now? what I feel is if Lav has to change towards T then it shud happen before she gets married and afterwards chances will be less-so in spite of all this she may get married to niteesh but before she steps in she wud have turned in favour of T.
Then only she may realise Charu's real face. because if lav is fav charu she may not know charu's true colour. remember what the doctor told TA . he said becoz of charu several people will face probs, so my guess is sudha, deepa and lav will face probs then only lav will realize.
def i think the purpose of the marriage to stop shud be there- my guess is VR and lav will change.
if VR changes then it will be charu's turn to show her true face.
