The Tron poster proves more than just a father’s nerdy gift to his son or a nostalgic pop culture reference. Originally given by Orion to a young Chuck, it also hints at their shared secret identity as Intersects. Not only did Chuck accidentally download a prototype of the program as a 12-year-old child before stumbling upon the 1.0 as an adult, but Orion also admits he downloaded an early version of his invention in Season 2.
The poster’s tag line reads: “Journey now into a startling new dimension… / A world inside the computer / Where man has never been / Never before now.” Though Chuck’s and Orion’s technical reality as Intersects is actually the opposite (the computer has traveled inside the mind of man), it remains central to their identities.
Figuring this unique dynamic they share, Orion and Chuck frame the poster between them in the scene when Orion strategically leaves the map of the Roark Instruments Intersect on his son’s bed (vs Dream Job). A complementary image follows later in the same episode when father and son frame the Intersect cube spinning between them at RI.
