I noticed that in this episode, Chelvi mentions Boss is the head of a medical research foundation. So by extension of being his PA, Chelvi herself works for this foundation. Can't she get Aish the proper treatment from there? Especially since Boss is jetsetting to UK, Canada and Aust (all in 1 week š and boss amma doesn't know where hubby is going? š ) that implies he has links to medical research in those countries. So if he is really such a nice guy, wouldn't he offer to help his PA's adopted daughter if he were to know she was sick?
Another point here: I hope "international medical research foundation" doesn't mean "global bioterrorism organisation" - remember, we still don't know who KT's boss is? Let's hope it is not Chelvi's boss! š
