1. She like to keep BB wondering who is waiting for AK and keep guessing, it will be a good brain exersice for BB and Alzhiemers won't hit him again.
2. May be she thought that if BB came to know that interzar karnewali ek ledki hain & AK cannot shift to MM because of her then he may shift to Allahbad.
3. She want to make BB jealous.
4. She was worried if BB want to keep her with her phonewali then she need to make baked kachori for BB everyday.
5. May be the female who is very attached to her is very beautiful friend of her and she is afraid that BB may attracted to her.
6. After the heartache given by BB to her, AK lost her all faith & interest on male, now she is only interested in female. After brain attack she didn't want to give BB a heart attack, so she did not disclose anything.
7. She is an independent woman, its her life, she discloses it or not, her wish. Uski marzi.
Phonewali ki raaz ek raaz banke reh geyi Aradhana ke dil me. 😔😲
