The Better Half
Lie to Me's "Undercover" episode originally aired in the U.S on April 29, 2009 on the FOX network.
The group investigates a controversial case about a cop who shot a teenager and the threat of a terrorist attack. Meanwhile, the Lightman Group is supposedly "sued" relating to the multi-million dollar scam, but it was actually a test for Torres' loyalty to see if she would reveal what Loker did (Lightman already knew). Loker is made an unpaid intern near the end of the episode by Lightman, instead of being fired as he was expecting.
- "Walk Away" by Joseph Arthur.
