These are my predictions:
1.) The supervisor of the gurukul Sanyogita is in won't believe Sanyogita (that she was the ghost) and she will have to continue her stay in the gurukul and think of other ways to get sent back to Kannauj.
--Or, Sanyogita's deed will be revealed but her plan will fail and instead of getting sent home, she will be given some other punishment or sent to a punishment village/camp or something.
2.) Prithvi will learn his second lesson that he shouldn't take the blame for things he isnt at fault for.
3.) Harya Singh will find Prithvi but as usual his friends will get there just in time and save him
4.) Or, when Prithvi encounters Harya Singh, he will gain an inner strength and courage and learn to use the sword again. (doubt this will happen though)
5.) Kadambari will start to fall in love with Prithvi
6.) Karan and Prithvi will become friends
7.) Rajkumari Indravati (or whtever her name is. the girl who wants to make Sanyogita stay) will become enemies with Sanyogita and they'll both try to make their plan work.
