"Chuck Versus the Undercover Lover" was one of two episodes aired on January 24 to close out the season. It was run at 8pm EST, followed by an episode of "The Apprentice", with the second episode of "Chuck", "Chuck Versus the Marlin", airing at 10pm. These were the last two episodes completed by the time of the 2007 Writers' Strike, which interrupted production of the series. Although "Chuck" received a full, 22-episode pickup for the rest of the season, Josh Schwartz elected to end with the episodes already filmed rather than restart production.
