Devon Woodcomb When originally cast, Devon was only planned to have appeared in a handful of episodes before being revealed as an enemy spy by the end of Season 1. However, because of the popularity of the character, this plan was dropped and Ryan McPartlin was added to the credits as a regular member of the cast for Season 2.[10] Devon has appeared as a recurring major character throughout the first and second seasons, and began figuring more prominently toward the end of Season 2 as his suspicions grew, discovering Chuck's spy life in "Chuck Versus the Colonel", when he begins to provide cover for Chuck. He primarily appears in plots involving Chuck's home life, although he has been indirectly involved with the spy plots.[2] For example, during a hostage crisis at the Buy More, Devon formulates a plan with Big Mike, Morgan, Jeff and Lester to take down their captor, Ned, who Chuck learns is part of a Fulcrum plot.[6]
