Maddy Osborne (Kassandra Clementi) is amongst those who will have life-changing injuries as a result of the tragedy after she gets under the rubble amid all the chaos.
Although Maddy is eventually rescued from danger, it soon becomes clear that her problems are just beginning when she's delivered some devastating news.
Maddy's arm is so badly injured that she is told that it will need to be amputated in order to save her life. Naturally, Maddy is horrified at the prospect of losing a limb and refuses to sign the consent forms, but eventually agrees to have the surgery after a heartfelt plea from Roo.
Maddy's family and friends rally round to support her in the aftermath of the operation to remove her arm, but what does the future now hold for the devastated teen?
