It turned out that nothing was actually wrong with her operation, the problem was with her best friend leaving a day before her operation. A certain section of the city's police force called Special Circumstances told her that unless she helped find out where Shay escaped to, Tally would never become pretty. Before Shay left, she had left Tally a coded note as to where she was going, a place called the Smoke. She had mentioned it before but Tally never knew exactly where the place was located. So it was when her parents told her to do the right thing and find this place for Special Circumstances combined with her desire to become pretty and spend her time with Peris, that Tally chose to find her friend and expose her new life to Dr. Cable. Dr. Cable provided Tally with all she needed to find her way to the Smoke and a special transmitter to alert them when she reached to Smoke so they could bring back all the runaways. Most of the people that had runaway earlier had been Shay's friends who left before their operations, but she chickened out when the opportunity arose to escape. So by following Shay's instrucions, she found a long rail road track and eventually came to a chasm large and seemingly unpassable. She had already almost fell off a different cliff and could not figure out what the "worst mistake" was that she needed to make, like Shay had told her. By the end of the chapter she decides to just lay down and try to figure it out the next day.
