Simran and Aastha come back home and everyone is happy about Astha's return including Saurabh. Aastha and Sia bond like sisters again and tell Sid about the turn of events. He is pleasantly surprised. At dinner that evening, Abhi's parents come over and his mother suggests that the entire family should go for a pilgrimage together. Everything is packed and ready when all of a sudden, Simran has to go for a eye donation campaign. She has to stay back and so, Aastha suggests that she would stay back with her while the others could go ahead as per the plan. The next day after she finishes the campaign Simran and Aastha leave together in Simran's car and on the way just as Simran and Aastha are discussing how happy all of them were, their car meets with an accident.
WELL I THINK THIS IS HOW SIMRAN WILL BECOME BLIND AND ASTHA MIGHT DIE AS OF WHAT IS READ IN ARTICLES ALSO SIMRAN MIGHT LOOSE EYES COS THEY JUST SHOW THE EYE CAMPAIN STUFF WHATEVER IT WAS.
