Adnan Syed, Sarah Koenig and Mailkimp: Interactive Graph Shows How Every Person Involved in 'Serial' Is Connected

In the latest episode of "Serial," host Sarah Koenig recalls a detail from a previous episode, saying, "No one but me probably remembers this now." Oh, Sarah, ye of little faith. Of course we remember.

With iTunes-record-breaking subscriptions, a Slate spoilers podcast for each new episode, and a diligent subreddit that picks apart every second of the show and a document from the trial, there's little chance of active "Serial" fans forgetting something. (If you did happen to forget, the moment Koenig is referring to can be found around the 8-minute mark of "To Be Suspected" -- when Inez recalled seeing Hae Min Lee buying hot fries at the concession stand after school.)

If you've been a casual listener to the podcast but are now ready to dive in, or if you just need a refresher on who Cathy or Aisha Pittman are, you have come to the right place. Building on the Reddit-compiled list of people who have appeared on the show, we connected and categorized each person to create an interactive graphic. How many episodes they've been featured in, when they were introduced, and how important they are to the series were all taken into consideration in the making of the "Serial" roster. The next episode of "Serial" doesn't air until December, but you can keep up with the investigation by checking out our episode recaps and interactive timeline.
