This episode was the first after Chuck and Sarah officially became a couple. Now, it can be a risky move for any show to unite its lead couple; you need to prove they’ll be as much fun to watch together as when they were gazing at each other longingly across the courtyard. We though, we had a secret weapon. Two, actually. Zac and Yvonne. In this episode — a mission on a train outside Paris — they proved they could play a kick ass couple who could also be in love. They’re charming and funny and romantic, and they proved we could propel the show in a whole new direction. - Chris Fedak and Josh Schwartz
