i think i can see tintiny's point too. really, are not some of the other guys around also diamond polishers? is there only nanaji and no one else? really, someone as successful as dm would make sure there was back up. and if he depended on nanaji so much, would have made sure he's hale and hearty with a comfortable heated house and a doctor on call. for a star employee, nanji is really badly rewarded for his efforts, which is so unrealistic.
as far as santu is concerned, love her. yes, she is a bt heroine - and haven't we all suffered with them - but a new, improved one. she's been shown to falter a lot of times, too. if they want to show her capable and intelligent, they should be careful not to do it at the expense of the other heroes of the story.
as it is, a lot of the ladies are watchin it for rr. dm has to rule.
