Back to page 34 in Cured by Bethany Wiggins,
I think that jack is going to find Bowen and fiona (from the first book of the series) and do something with them. I think this because she left a note saying "I am going to live inside of the walls". However, this might as well be a distraction to her actual intention. I believe that she too will find romance (without romance, this wouldn't be a Bethany Wiggins book. Lets be honest) in this world, where she only wishes she could have the romance on fiona and Bowen.
