Homer and Bob end up giving chase to the killer, who is revealed to be Frank Grimes Jr, the illegitimate son of Frank Grimes, who blames Homer for his father's death. Junior attempts to kill Homer, but is foiled when the police arrive. That night, after Homer puts Bart in bed, Bob takes possession of the remote for his shock bracelet and sneaks into Bart's room, intending to kill him. However, Bob realizes he is accustomed to Bart's face and cannot bring himself to do it. He tries to take his leave, but gets zapped continuously by his shock bracelet (because of birds pecking the remote after it landed in their nest).
