Nikki gave the perfect answer “I had it in my clothes, I didn’t put hands in your clothes.” That’s the end of it. She could never get it from Rahul by force.
That is besides the point. Like I said previously, they are unmatched in strength, sure - but at least there is a match - whereby both can try, and one will fail. When she put it down her pants - there was no match to begin with, because it meant Rahul couldn't even play. To me - that's not a fair strategy - and BB shouldn't have accepted it.
