At the end of Chapter 106, Gabrielle is breaking into Senator Sexton's office. To get to the office, she "climbed up the shelves, popped out the fiberboard ceiling tile, and pulled herself up". In the next paragraph, she was "lowering herself through the ceiling of Sexton's private restroom". This is not possible - if she climbed straight up through the ceiling, she would be entering the bathroom through the floor. Even so, this would be unlikely, as the floor would certainly not be so flimsy as to be popped out.
[No, the bathroom is on the same floor as the office. She climbed into the ceiling of the office, moved through the dropped ceiling until she was over the bathroom, then popped out the bathroom ceiling tile and lowered herself back down.]
