Chuck Wiki
The Intersect

The Intersect Room

The Intersect is a government database of encoded information harvested from every intelligence agency in the United States, including the Central Intelligence Agency, National Security Agency, and the National Clandestine Service as of the Season Four episode Chuck Versus the A-Team.

Throughout the series, the Intersect serves as the core of the story line, after Bryce Larkin sent the First Intersect to Chuck. Various organizations strive to obtain the Intersect, or human agents who may have the Intersect installed, commonly referred as a human Intersect.

The initial upload of the Intersect apparently took far longer than any subsequent update or download.  The implication is that Chuck was receiving for what may well have been hours, since dawn arrived as the download completed. 

The 2.0, by comparison,  took only minutes to upload to Chuck, and updates even less time.


Prototypes/ early versions:

Main Intersects:

Enemy Intersects[]

  • Fulcrum Intersect - The Meadow branch and the Roark Intersects developed by Fulcrum.
  • Ring Intersect - Intersect built by The Ring, uploaded by and used by Shaw.
  • Intersect 3.0 - The ultimate Intersec, subsequently infected with the Omen virus by Chuck.

Human Intersects[]

Following 9/11, the CIA and NSA were instructed to "play nice" and share their intelligence, in turn making it easier to track and identify threats to national security, and the manufactured Intersect is "how (they) did that." They put "every scrap of data (they) had" into the computer, and the Intersect "saw" patterns in the data that the agencies had not.

For example, Chuck describes in Chuck Versus the Intersect that multiple agencies had picked up information suggesting a bombing attempt against General Stanfield during the speech he was due to give, but the CIA and NSA each only had part of the picture. The Intersect cross-checked and combined both groups' intelligence to determine the full nature of the threat. Dr. Howard Busgang (code name Perseus) was one of the technicians involved in its design and development, as was Dr. Jonas Zarnow. The chief designer is Stephen J. Bartowski (code name Orion), Chuck's father. Stephen Bartowski was apparently unaware of what the government intended to do with the Intersect, and it is not entirely clear what he originally expected or if the government had designs for the Intersect beyond creating more powerful spies. Both he and Dr. Busgang refer ominously to Stephen learning about the government's plans for the Intersect. When Stephen did learn, after completing the original Cipher, he purged his personal records and disappeared, not government or hostile agency was able to track him.

Intelligence Updates[]

In Chuck Versus the Break-Up, Bryce leaves Chuck a pair of sunglasses equipped and designed to update a human intersect, and was coded to initiate upon recognizing Chuck's retinal pattern. The sunglasses needed the Intersect Data Drive in order perform the update to the Intersect with new intelligence.


Chuck uploading 2.0

In Chuck Versus the Suburbs, Chuck is exposed to two test sequences of encoded images designed by Fulcrum in their attempt to build their own version of the Intersect, a short test sequence followed by the full test. He believes that Fulcrum programming could be in his brain, this is proved by the subsequent flashes on all his cul-de-sac neighbors, all of whom are Fulcrum agents, and none of whom prompted a flash from the Intersect when he first encountered them.

In Chuck Versus the Last Details, one of Chuck's flashes contains information on Vivian Volkoff's possible bases of operation - directly naming her in one of the encoded images. When Chuck last received an Intersect update, Vivian was not in command of Volkoff Industries, nor was she even aware of it's existence. This suggests that Chuck's Intersect is updated more frequently than shown with new data from the CIA and NSA.
