It is revealed that Jake's favorite musician is Taylor Swift.
First time we hear Terry's exasperated "WHY?!" which eventually becomes a recurring catchphrase of sorts.
The solution to the "Unsolvable Case" is incredibly similar to Peter Pettigrew in Harry Potter: Both men faked their own deaths by seemingly being killed by a close friend in a blast, leaving nothing behind but a finger they had removed themselves. The biggest difference is Pettigrew framed his friend for the supposed murder, while Nate Dexter framed and killed his friend.
