Lots of doubts

I had stopped watching the show after meethi-akash and ambika(i think i am correct about her name...the one who wanted to marry akash)-akash's bro(forgot his name) marriage. Can anyone please brief me what happened. Is ambika rathore's daughter? Did her truth came out? Did amma accepted meethi? I understood that yuvaan is meethi's brother, came to take revenge from mukta. why is vishnu behaving weirdly? How come akash's bhabhi(forgot her name) in brothel? n how meethi in brothel?

Ambika wanted to marry Akash , but as meethi was in the middle, she tried to take revenge from meethi !

she acted as if she burned herself... and meethi was balmed

meethi was given hanging decision for killing ambika.. but fortunately ambika's truth was out, so police arrested ambika

Meethi found that kajiri ( bhabi ) is taken into Kota,so tries to save her.

the owner, Maharani kidnaps meethi for releasing Kajiri !

again, Akash , rathore and kanha do some tricks and saved meethi from maharani, maharani dies in the temple..

as he went to jail because of Muktha, he is back by changing his face to take revenge from muktha !!

Vishnu : in revelaing Ambika's truth drama, Ambika takes the gun and shoots.. it nearly hits Vishnu's head.. so vishnu starts bleeding, but nothing happens..

but later, the affect is that he got memory loss problem.. he forgets few things and regains them too..

Vishnu finds the truth that yuvaan is yuvraj.. but Yuvraj kidnaps him and hv given him overdose of drugs, as a result, he is in coma now !

She is in Jail now
