"Happy Go Lucky" was the twenty-first episode of the second season.
As Aaron Echolls' trial is about to conclude, tensions rise as Veronica, Keith, and Logan take the witness stand and testify against him. The defense insinuates that Veronica is promiscuous and had come on to Aaron as part of their attempt to impeach her as a witness.
After Veronica finds a suspicious e-mail on Woody's computer, Keith turns to Sheriff Lamb with evidence to arrest Woody, but Lamb refuses, believing that Keith is trying to turn him into a laughing stock.
Terrence Cook is exonerated when Leonard Lobo reveals that he was at his casino at the time of the crash and thus could not have made any cell phone call to cause the bus crash. Lobo then visits the Cook residence and tells him that to work off the favor and his debt Cook will now be working as a casino operator.
To everyone's surprise, Lucky brings a gun to Neptune High looking for Gia. Wallace attempts to subdue him when he threatens Jackie but is overpowered. Just as Lucky reveals the pistol is only loaded with blanks, he is shot to death by security.
Veronica, on the cusp of winning the Kane Scholarship, decides at the last minute to blow off a test to attend the reading of Aaron Echolls' verdict. She is stunned when he is acquitted on all counts.

- Wallace: Well, I gotta go clean out my locker.
- Veronica: You got that salmon I left in there for you, right?
