As much as i want Arti to be out, she won't be yet. She'll get more votes than Arhaan, Bagga & Madhurima for sure.
Bottom 2 will likely be Bagga & Arhaan. If double, then both will go.
If single, then both are neck & neck in terms of votes. But given Arhaan's great PR game, he might be able to pull more votes than Bagga.
I'd advise Rashmi fans to throw some votes to Bagga, if they really want Arhaan out.
