Guys ! What is really happening here

I missed out on a few days of episodes and everything changed... What happened that was so drastic that Saachi is killed and introduced as a new person...

Sanchi is killed by ArChi themselves according to their Plan ,actually ArChi or Sanchi have no evidence to prove Aryan's innocence bcz that video which can proved his innocence is destroyed by Nikita&her uncle etc.u can watch Latest segments for more info.Kaki sa (Nelima) is helping them.
