Given the history where Taliya is consistenly fooling abhi and pragya from years (and even when caught, paid nothing as pragya and abhi are either too mahaan or too dumb), is fooling pragya again that difficult? and we have seen it countless number of times, pragya and abhi share such a great level of communication that less said the better. Though agreed, blood cancer/brain tumor sounds serious and might be a possibility that writer will not go there otherwise how will they show childish illogical romance in front of life threatening danger..from assassin to fires... but pragya did get shot, abhi did get involved in a severe brain damaging accident, purab did get crushed by a truck and pragya sister did died after some gruesome antics. So i am like 50/50 that writers may even go ahead with the brain tumor/blood cancer. Also as this will be part of tanu/aliya plan, so tanu aliya will get consistent screen space and also "to the viewers" , the lead character will not be in danger (but more like getting fooled by villains) so they might accept it.
