Yes, good title, an apt fit for the situation. Barkha in her over confidence did not think much over the fact that BB could ruin her plans. BB went and calmly brought back Rads in time! hehe. Barkha was left frustrated!
BB knows about Barkha...and also about Rohan. So she is an indirect shield to RaDev's love. She might not be their well-wisher but at this point, she is a somewhat safe person to rely on than Barkha.
Rads visit to the temple did reap her benefit. Lord Ganesha brought the obstacle of her life in front her her, through BB. ;)) Radhika needs to cleverly think and put this Barkha in to her place.
