the fact is that tanu can have the same effect on abhi as pragya...she did a lot worst..when he gets a flashback about tanu...he will not drop down in a seizure...so why say it is only pragya he must keep away from...logic we don't expect but nonsense rules the roost...and dadi started up about not wanting tanu and then for the stupidest of reasons when alia told her if she will tell about tanu to abhi she shut up...which of course is a pack of hogwash...the fact is that everyone hurt abhi which he has forgotten or not...so everyone including alia could trigger abhi's mental or stroke or whatever it is that he can suffer from...so this keeping pragya away from abhi makes sense as much as a two headed donkey...pragya did nothing to hurt him...his memories of her will be positive...as unlike the memories of tanu and alia...so in fact they are the ones that are the most dangerous to us health...
