For the pier scene, the stunt zombies (and Madison's double) had to jump 35 feet into the sea.
The characters in the episode title don't actually appear. Pablo is the name of Luciana's brother whose body has finally been found, torn to pieces. And Jessica is the name of the bride at the hotel. As played by Schuyler Fisk, we saw her briefly in the previous episode; her character is just an unseen snarling presence behind a hotel door in this episode.
This marks the first time in the series that the episode title is made up of a character name.
