In today's episode, Padma brings a CD of Arijit and Arpita, which reveals the facts. I think Arijit now realised how Rex used him to vote out Kirti, Shamit. Also earlier Arijit was brainwashed by Shamit to vote out Kirti. What Arpita saying is not true. She too had joined Rex in this plan. QAZI IS THE WITNESS TO THIS AND SO WHILE VOTING ARIJIT HE LOOKED AT THEM AND SAID " you are challenge to all of us here and I accept this challenge" QAZI WILL NOT TELL LIE OR OTHERWISE. He understood and heard REX AND ARPITA'S MIND. HE STILL STICKS TO HIS VIEW POINT ON ARIJIT.
Sandeep too did not want Arijit because he knows he will loose out to Arijit AND HENCE NOW TALKING AGAINST HIM. Arijit will not simply say it. He thought when all would vote this way then why not he ? Hence he followed them. I feel Arijit was used by all of them.
