Juliet's first cue card. ("The Cost of Living")
In the episode "The Cost of Living", Juliet showed Jack a video tape, which she told him is the movie, To Kill a Mockingbird. However, she turned the monitor of the TV away from the cameras so that only Jack could see it, to avoid the content of the movie being detected by Ben through video surveillance.
Secretly, she communicated with Jack without Ben knowing, through the use of silent cue cards. In contrast to what she said verbally, on the cards she told Jack that Ben was a liar, and conveyed a plan to kill him.
The video was shot in Juliet's house at the Barracks as was evident from the background. The framing of the cue cards changed between the first and second card. The change took place on the TV screen Jack was viewing. When the first cue card was seen, Juliet's face could be seen as well. When all the other cards were seen, the shot was zoomed in to show just the card. It is unclear who, if anyone, zoomed the camera in while filming Juliet.
In the menu of the third disc of the Season 3 DVD box the full video is shown as an easter egg. Juliet had 2 extra cards after number 10. The first said, "I promise," and the second said, "By the way, your ex-wife is much prettier than me." There were no close ups of the cards in this version. The video is shown in a TV in the menu, and a video distortion effect has been added to it.
