Prove innocence but jassi is not innocent

But what jassi did was wrong, yes u should give answers to someone who bullies u but falling to their level? 

Yes ankita burnt jassi's papers so jassi did the same to ankita 

I mean ria stole jassi's idea and the reply given by jassi to her was just perfect - she taught her a lesson without falling on her level of cheating 

See I know jassi deserves to win this but how will she prove that she didn't start the burning of papers? And even if she will how will she justify herself for doing the same?
