His words were ...its nice that you came back..you know rana ji started to laugh again...he is getting close to his new Queen gayatri ..
so what it indicates? -
Rana ji's first wife had married to him as per chacha's evil plot ..and both faked her death..in that way rana ji went awy into depression.. in that meantime he ignored his duties ..and chacha wanted that he should be dead soul so that he shouldn't pay attention on his subjects ..and it will help to chacha to blame rana ji for not being a good king ..
but now he is happy man ,in this way he might tight his clutches over his kingdom ..hence chacha brought back sulakshsna in the picture ..chacha is thinking that sulakshana should make mad to rana ji again by pretending sula is back ..
guys positive side is that in the end rana ji will find out that sulakshsna never loved to him..she married to him for money only..in this way there won't be any place for sula further in rana's heart..
by this way rana ji will realise only his second wife loves him no this first wife!!!
