Chuck Wiki

Mary with the device

The Intersect Suppression Device refers to a small black portable device, first seen in Chuck Versus the First Fight, apparently designed to render the Intersect largely inaccessible, it does not, however, erase the Intersect, as was seen by Chuck's many attempts to partially access a flash, but never quite fully. The erasure device was first developed by Stephen Bartowski while incarcerated at the Starbrite Drive-In Fulcrum facility in Chuck Versus the Colonel.

Whilst Chuck is in his father's base attempting to get the Phalanx XR-12 computer to read a SIS disk supposedly containing evidence of his mother's innocence, Mary takes the device from a storage box labelled "Eurybia". She then powers up the device and displays it to Chuck, saying his father never wanted him to see it. Blue images flash up as a video stream. This has the result of suppressing Chuck's ability to access the Intersect 2.0, preventing him from fully flashing. Fragments and incomplete access is all that he can achieve.

In Chuck Versus the Fear of Death, however, Chuck undergoes a month of intensive assessment and treatment designed to break the block and allow access the Intersect 2.0 letting Chuck to flash once more. The CIA scientists conducting the assessment concluded that the device hadn't damaged or removed the Intersect but merely suppressed it, making Chuck unable to complete a flash. After weeks of testing, Chuck flashes multiple times, but the contents of the flash are static. It is after the failure of the testing that agent Jim Rye is brought in to instill a fear of death he hopes will kick start Chuck's access to the Intersect. This treatment ultimately fails as well and leads directly to Chuck's capture by the Belgian. It is not until Chuck Versus the Leftovers that he regains full access to the Intersect through a reboot from the Intersect laptop left by his father.


  • The suppression device is clearly a modified Sony Playstation Portable, notable for its distinctive shape and shoulder buttons. However, the device has a different face plate and input panel.
  • Eurybia is another code name based on Greek mythology, in myth Eurybia was described as "having a heart of flint within her", she was known as the ancestor of gods.
