In its fourth week and also just a week away from the mid-season finale, Bigg Boss 13 is now turning into an interesting affair. Going by Wednesday's episode, it was quite an entertaining one. From Arti Singh and Rashami Desai's fight over Sidharth Shukla, a new ticket to finale task getting introduced to the wild card, Shefali Zariwala watching the contestants from the secret room, Day 30 was a roller-coaster ride.
