A renowned urban vigilante is killed after making another citizen's arrest, and Five-0 delves into the world of super heroes and comic books to find the killer. Also, Adam finally gets closer to finding out who killed his sister.
- When Jerry and Grover first visit the comic book store, the theme to Star Trek (1966) was playing in the background.
- When Adam and Jerry go to Gene's apartment Adam notices the Ultraman action figure in Gene's apartment and mentions that he was a big fan of the show.
- Noelani Cunha did not seen in this episode.
- The 20-year-old tape Trevor Wahale is in the 16:9 aspect ratio of high-definition TV. While HD broadcasts in the US began in 1996, and it's not impossible for Trevor's station to have HD equipment (though fairly improbable), the name/station logo graphic seen in the recording is clearly formatted for a 16:9 screen. Most people would likely have SD 4:3 TVs at the time that would cut off the sides of the image, and as such, the graphics would be designed to keep the name and logo within the 4:3 frame.
- Despite being credited, Kimee Balmilero do not appear in this episode.
