The Saviour's illness- part 2

IwKa asked for a oneshot of a sequel to Ch2017 "The Saviour's illness".

The more time went on, the more Snow and Charming felt like they were in a sand timer. There was still little light shed on what was causing Emma's illness. They knew it was something to do with being a Saviour, but beyond that, they were clueless. How could being a Saviour affect your health in such a way? None of these people were in any way biologically related, so there were no shared genetics. They hadn't been in contact until both had contracted the mysterious illness, so neither had passed it to the other. Nor had either Aladdin or Emma passed the illness to anybody else. That's, along with Jafar's smug message, was how everyone knew this had something to do with being a Saviour. However, that was all the information the parents had on what was slowly (possibly) killing their daughter. Every day she got a little worse. Every day the normal things a person might do were just a little bit harder for Emma to do. Every day, she lost a little more hope. Snow, Charming, Killian and Henry had all tried to keep her hopes up. Heck, even Regina had a go, but nothing worked. Emma was certain this was it. The final curtain. Snow and Charming just didn't know what to do. They were trying everything they could to find out what was causing this illness and find a cure, but everything they tried turned out fruitless. Time was running out for them. Time was running out for Emma. If they weren't able to find a way to reverse this…they just didn't know how they'd be able to live with themselves.
