Bullock's past comes back to haunt him when he and Gordon investigate two murders at The Sirens. Meanwhile, Bruce and Alfred explore the tunnels beneath the city, and Penguin and Nygma's plans to escape are thwarted by the least likely of suspects.
- This was the 99th episode to be produced (production code T40.10061) and the 96th to be aired.
- Bullock's former partner Detective Dix last appeared in "Spirit of the Goat".
- Arthur Penn reappears and is revealed to play an iteration of the Batman supervillain The Ventriloquist. Originally, his role as Ventriloquist was going to be cut from the season due to it being shortened. However, FOX was granted season 5 two extra episodes which allowed the producers and writers of the show to go ahead and use Penn one more time. Although he is shown with Scarface, Penn is never once referred to as the Ventriloquist.
- At one point in this episode, Cobblepot accidentally called Arthur by the name of "Arnold". In the comics, the Ventrilonquist is usually known by his real name Arnold Wesker.
- Following the airing of "Nothing's Shocking", actor Andrew Sellon was later made an honorary member of the International Ventriloquist Society for his work as the Ventriloquist on Gotham. He also discussed the filming of the episode in an interview published in the Ventriloquist Society's June 2019 issue.
- The supervillain Jane Doe debuts. In the comics, Jane Doe is an Arkham Asylum inmate who stalks people, learns everything about them, murders them, and steals their identity, disguising herself and living as them.
- Though this version has shapeshifting powers as the result of being experimented on at the Indian Hill facility.
- The title of this episode references the Jane's Addiction album of the same name.
- As confirmed by Gotham writer Tze Chun, the coat worn by Bruce Wayne in "Nothing's Shocking" and various other Season 5 episodes is a reference to the 1987 comic book story arc Batman: Year One by Frank Miller. In the Year One comic, Bruce Wayne was seen wearing a very similar coat.
- Goof: When Penn fights Oswald, it can be seen that Scarface's hat falls off when Arthur hits Penguin with the dummy. However, in the next shot, Scarface is wearing the hat again, even though it fell off in the previous shot.
