Deliberate mistake: Right after the credits, we see an establishing shot of the mayor's house but it's a reused shot from episode four from when Jake and Lexy snuck inside, just without the digitally added smoke. What gives it away?

Answer: They were blamed for the death of Jake's foster brother, which was deemed a terrible accident, and they were sent to the reform school as a punishment. Presumably, when they had to leave the reform school given what happened, they were instead given community service as punishment.
