How soon?? no where in the near future....going by the BT history they wont reveal prem's innocense for another few months....First they will show Prem heer meeting then prem coming to know of their daughter ....and how he tries to win heer's trust and love to get her back in his life....their daughter playing a major role in that ....and when heer is almost home,ash will enter with a kid and create problems...and then finally prem's truth will be out and heer willcome back saying all sorry and stuffthats what usually happens in BT land , but Kis desh and its creatives have always been different and has managed to surprise us....but still , If prem's truth comes out soon , heer will come back to him in no time...then the creatives wont be able to show the passionate love story of Prem winning his heer's love back again..so i guess they will drag it...gayathri's truth will never come out...she will remain in everyones good books...unless and until she confesses herself...even if the veera did her abortion truth comes out, nobody will blame G3 for punishingnihaal coz they'll say veera had misled g3 and she isnt at fault....EVen if Maya opens her mouth and says that G3 wanted heer out of the house and so created probs between PRemeer still nobody will bother to be angry on her coz heer left the house coz of premSo will remain in Heer n PRem's good booksSameer is dead and I dont think rajveer after 6 yrs will come back and prove that Gayathri was behind Sameer and the one responsible for heer's miseries during that time, so again she 's savedONLY if Ash comes back and says that G3 was the one who made her do it to seperate premeer , will gayathri's all truth will come out and everyone will hate and punish her
i also agree i think ash definitely knows gayatri's intentions of prem-heer separation and when ash will be back she may ask her to help but when ash's truth will be out no one would spare her specially prem and heer and then she will say that about gayatri and her truth will be out.
