If the last episode of 'Chuck' felt like a season finale... well, it's because it was. The episode was initially supposed to have a thirteen episode season, but NBC decided to order another six episodes. According to Chris Fedak, who co-created the show with Josh Schwartz, the good news came at an opportune time: as they were writing episode thirteen.

In our wide-ranging talk, Fedak and I talked about how the pickup affected the writing process, how the new dynamic between the characters on the show is playing out, if he fears the energy will fizzle, why Tony Hale wasn't around this year, and if he's confident the show will get a season four.

(Warning: Fedak talked fast, so this is a long interview, with a very minor spoiler near the end. But there's a ton of good info for 'Chuck' fanatics, so read and enjoy!)
