However I don't think it's true.
1. Have they ever mentioned that she suffers from polio?
2. Anji prolly had a rich childhood, so her parents were able to afford polio vaccination for her.
Hence my deductions is that her limp is not because of polio, but rather something else...maybe an accident or something when she had as a child fleeing from Mr.Malick (her uncle).
I just hope she gets cured of her limp! maybe the electric shock will rejuvenate the nerves in her legs? Devi Maiyya kripa karo!
What do you guys say?
