Meanwhile, Logan is complaining to Avi Kaufman, the manager of Aaron’s estate, that there is money missing from his trust fund. Logan threatens to have lawyers look for improprieties in the management, a threat to which Avi responds by offering to provide Logan all of the fund’s records. Later, Logan brings Veronica, who has offered to enlist her father’s accountant to help self through the records for foul play, to collect 10 full boxes of files.

Harmony Chase, an acquaintance of Keith’s, comes to his office with suspicions that her husband is cheating on her, citing late working hours, “mysterious calls”, and last-minute business trips as reasons for suspicion.

Wallace shows up at the library while Veronica is on the job to show her a front-page article in the paper linking the campus rapes with Pi Sig events — complete with a statistics graphic.

Dick, a member of Pi Sig, visits Veronica at the Mars’ apartment to ask her to clear Pi Sig of the rape charges, as the issue has apparently escalated to requiring a hearing on Pi Sig’s continued endorsement as a fraternity at Hearst. Veronica agrees for $1500, her real motivation being the full access to Pi Sig behind-the-scenes Dick promises.

While Veronica dons a pantsuit for her foray into the Pi Sig frathouse, Keith over does it on aftershave for his meeting at the office with Harmony, and lets Veronica know that his accountant is still looking into Logan’s files. At the office, he tells Harmony that he saw Carly Hern dropping Marvin off at his workplace. Though Harmony is less jealous and relieved about the woman on the side not being a midlife crisis fulfillment for Marvin, she agrees to bug Marvin for audio surveillance.

At Pi Sig, Veronica talks to Charleston Chu, who was tending bar at the party Clare was at and came up as the number one suspect in her rape. She tells him as much and he tells her that Chip Diller was apparently caught in flagrante (or naked, sweating, anxious, and locked away in his room) during the party. While she is attempting to get to the bottom of whether or not the Pi Sigs are involved in the rapes, the campus feminist group has gathered in a mob outside the house.

Keith and Harmony appear to have forgotten their important appointments entirely in favor of telling their life stories to each other. Veronica and Logan interrupt, at which point Harmony departs. This gives Keith time to explain to Logan that the disappearing money, $10,000 per month, is being funneled into “Aaron’s Kidz,” a charity run by Avi Kaufman for Aaron.

Veronica, having lunch with Logan, confronts Chip, who seems to have bruised hands (apparently stepped on by a brother during the Halloween party). He also explains that he wasn’t raping anyone and that the girl who he was with when Charleston came to his door was his girlfriend. Shortly after Veronica corroborates Chip’s story with the girl, Dick shows up to hassle Veronica about her slow pace. She sees that his hand is similarly bruised like Chip’s was. Dick claims that a window fell on it.

While investigating the money laundering, Veronica follows the money through Aaron’s Kidz (different from the Aaron’s Kids charity that they initially thought it was) and into a wide variety of various other companies until they find the source: Charlie Stone. Veronica reveals to Logan that Charlie Stone is his half-brother and that he was getting $10,000 per month in “hush money.”

Logan calls Charlie looking to meet, and Parker complains that Veronica should be taking a more confrontational approach to hunting for the rapist instead of working with the Pi Sigs. Parker makes several revelations about Dick Casablancas: She met him at orientation and thought he was cute and he also chased Nancy (another victim) out of the Pi Sig haunted house, screaming at her.

While trailing Carly and Marvin, Keith manages to get a picture of the two kissing briefly outside of the restaurant.

When confronted by Veronica, Nancy explains that she was chased out of the Pi Sig house when she and Claire attached rat traps to their “grope-able” body parts and walked into the Pi Sig “grope room” in the Halloween house. After being chased out of the house, she lost track of Claire. Later that night, Nancy thought she saw Claire down the street from the party, but claims it couldn’t have been her, because the woman didn’t respond when she cried out her name.

Veronica, however, knows that people under the influence of powerful rape drugs aren’t among the most alert, so she visits a convenience store down the street. The clerk verifies that Claire was at the store with a young man, buying condoms. He also mentions that he pointed the two towards an ATM when he wouldn’t accept a credit card for less than $15 worth of goods.

Logan has a few beers with Charlie Stone and they agree to continue the brotherly bonding over surfing. Veronica walks in just in time to meet Logan’s newfound half-brother, but something about him makes her suspicious. Veronica decides to look into his background to see if he’s what he claims to be. At the private school where she tracked Charlie down to, Veronica finds a entirely different person answering to the name of Charlie Stone.

Meanwhile, Logan and Fake Charlie are surfing and Logan tells a traumatic story about Aaron snapping on Christmas one year when he was a child. When they return to the beach, the brothers find Veronica, who reveals that Fake Charlie is actually Norman Phipps, a contributor for Vanity Fair. In response to this, Logan decks Norman.

At Mars Investigations, Keith presents the pictures he took to Harmony. But, the bugged conversation proves that Carly was the one who was pushing Marvin into an affair, which he rebuked. Marvin ended the potential for an affair when he handed her account off to a co-worker named Darryl Derryberry.

Veronica uses Keith’s bank connections to get a picture of when Claire was using the ATM to get money for the convenience store earlier, showing her with a decidedly sober non-brother of Pi Sig, thus fulfilling her contract with the fraternity. Although justice was found for the frat, it means that the “Greek Chorus of Feminist Shame” (Nancy, Claire, Parker, Nish, and some extras) can’t shut down the Pi Sigs with a rape allegation.

As the real Charlie Stone is mobbed by reporters, Veronica calls Parker on seeking retribution against a group of guys who, although aren’t upstanding members of society, had nothing to do with her rape.

Later, while Veronica retrieves Logan’s watch, given as a gift to Norman, Norman lets Veronica know that the real Charlie hadn’t gone public about his genetic identity, as Logan apparently believed. Logan calls Charlie Stone to apologize for accusing him of fame-seeking, and hoping to start a brotherly relationship with his real half-brother.
