The children are now one year older, and some are striving for more independence. Zoe starts to take charge of her own future and surprises her mum by deciding whether or not to go through further surgery on her arms. As William's behaviour starts to deteriorate further, his parents begin the search for answers. Only a detailed MRI scan can reveal if he will need to go undergo brain surgery for the second time in his life. And with Shelbie continuing to require 24-hour care, seven days a week, just to keep her alive, her parents are forced to rethink the way they look after their daughter.
