its quite funny when watching Ks i noticed that even though Pia hates (i think thats a string word) Bani so much she still calls her Di not just in front of her but all the time normally. as i would ahve though as u are ruining this person life u wouldnt give them somewot of respect like calling her Di.
n ma second point is abt roshini have u noticed that when she talks evil so to speak she has a stright face as if she is talking complete sense- like normally sometimes when people are evil n they start talking abt how to trin someone or them them wot they are doinng their voice gestures changes but Pia's dont she always calm
