The term Wrist computer refers to the specially-designed computer Orion (a.k.a. Stephen Bartowski) keeps on his left wrist during second season of Chuck. The computer is able to perform such tasks as control MQ-1 Predator drones, send messages, override doors and security systems. The device can display the user's location inside a building with walls, doors, and nearby humans visible on-screen. The device was first seen in "Chuck Versus the Predator", and later appeared in "Chuck Versus the Dream Job" when Chuck's father revealed himself to be Orion. Towards the end of "Chuck Versus the Ring", Stephen gives the wrist computer to Chuck, but it has not reappeared in subsequent episodes which left many fans wondering what happened to it.
