As the townspeople enter the church for Carl's funeral, and then again when they sing a song, organ music is playing, but in the background, nobody is sitting at the organ.
When David tells Stevie that the recently arrived Sean, Bree, and their baby are "scaggy", Stevie informs David that Sean and Bree are her cousins. David then shows surprise as he makes a connection in his mind that Stevie must somehow be related to the recently deceased Carl. However, there is no dialogue from any character up to that point which connects Sean, Bree, or Stevie to Carl in any way.
