I used to feel equal parts sorry and pissed off at Aarti’s utter lack of self-respect and desperate dependency on her friendship with Shukla. Now it just irritates me - she literally has no other relevance.
I have crossed my irritation faze and reached go pitty faze. She's has lost her self respect now. Remember she was praying loudly before the bank task "God I want to win by playing fair" 
Since then she's going lower and lower so much in the fairness meter that she's now the most faltu/unfair/lying/betraying/mean/treacherous character. She's consciously at the mercy of Shukla. She lies on purpose blatantly to both sides. She has lost her identity now.
