On the second episode of NBC's new series Chuck, there was a rare cross-network reference.
The basic plot of the show is that Chuck accidentally "downloaded" all of the United States government's secrets into his brain via a government program designed for exactly this purpose. When Chuck sees a seemingly harmless picture from this program, a government secret is brought to the forefront of his mind.
In this second episode, a doctor tests Chuck by showing him images that trigger these secrets. As the images fly by, Chuck begins spewing out government secrets. The audience hears only half-secrets, so we don't know the full details, but we are aware that the secrets are out there. After mentioning something about a presidential assassination attempt, the next fragment of a secret we hear is:
Oceanic flight 815 was shot down by –
Of course, this is a reference to the airline and flight that crashed in the series Lost. We obviously don't hear the rest of the secret, but hearing that in the list was certainly fun.
What's amazing is that NBC allowed an ABC reference on one of its shows. Clearly, the writers of Chuck are aware that many of their viewers are also Lost fans, and this is why they slipped the reference in. Can it be that the NBC staff responsible for viewing the program let this one slide, or did they simply not recognize the reference to the ABC show?
