At the end of the previous episode, the parole agent tells Willa that she is lifting the ban on internet usage as long as she uses it under supervision. But at the beginning of this episode, Willa makes a big fuss over the fact that she is not allowed to use the internet when Walter asks her to do some things, and insists that Walter needs to take Leo out and keep him busy so that he won't catch her on the computer.
The giant timer visible when Walter and Willa are trying to discover the broadcaster's identity after having narrowed down his location has just over two hours on it at the start of the scene, but by the time Walter explains to Willa what they'll be doing, the time has gone down by approximately 50 minutes.
Walter proves that the voice on the track is edited due to the yellow lights lighting up, however all the other audio played through the same machine still lights them up.
