When Rubina read the rule book about what counts as a piece of item, it was clear that her argument ain't valid, so I didn't understand what was she trying to prove. Like Abhinav said, she was a bad lawyer.
Hina was technically right that there's nowhere written that a pair of shoes can be counted as one item, and it's subjective to interpretation. I loved how Hina made Rubina's argument backfire and made her look like a fool in front of everybody.😆
