Like a Virgin

All the students at Neptune High have taken the latest online purity test, and someone is leaking the results. One "exposed" cheerleader turns to Veronica and computer geek Mac to reveal the hacker behind the spread of what she claims are faked results. Keith helps Wallace and his mom with an unruly tenant in their building. Later, Veronica arranges a prison visit with Abel Koontz, the man who confessed to Lilly's murder.
