What Maharani could do?

I believe Maharani offered Ravi to come to 17th century so that he can get reward from king or he can look 17th century since he is from archeological department and would be interested in seeing 17th century. 

Once they come, they are arrested so Maharani don't have any option left. It is fault of narrow minded King who punishes the man who helped her wife. 

What happen to Kings Vachon that 100 culprit can be released but no innocent should be punished.

I don't think she willingly brought him to 17th century! Because when they showed some glimpses of flash back scenes, Ravi wasn't seemed to be in his sense while Shuseela was shouting his name from their house..

I think Maharani did something to Ravi, which made him lose his conscious, like Tara did to Dhruv while she took him to Railway track to find Navrangvan..

After they entered to 17th Century, Ravi might got his conscious back and started to look for his family but ended up in prison as a Culprit.. 

Let's see! What CVs show...
