To comfort Megan, Julie reveals that she lost her own father at a young age . When Ray and Julie leave, Julie tells Ray what she found out . They head to Helen's apartment, where they find Elsa tormenting Helen about the attack on Barry . Elsa reluctantly leaves when they arrive, and Julie wonders if Elsa could be responsible for the threats and attack; she had always been jealous of Helen and may have learned about the hit - and - run by accident, as the sisters shared a room when they both lived with their parents . </P> <P> Ray calls the hospital and learns that since Barry was shot in the spine, he's paralyzed and it may be permanent . Ray sneaks into the hospital to visit Barry and try to talk him into dissolving the secrecy pact . Barry refuses, lying that the shooting was a robbery that had nothing to do with the accident . But thinking back to the night of the shooting, Barry recalls that he was lured out by an anonymous caller who supposedly had photographic evidence of the accident and would give it to Barry in exchange for money . Barry fell for it, agreed to meet the caller at the University athletic field, and was shot . </P> <P> Leaving the hospital, Ray sees Bud and they have coffee together . Ray says he will get Julie back and Bud challenges him, then says Julie will not go to Smith College because of him . Later, Collie appears in Helen's apartment and solemnly states that he is Daniel's older brother, he shot Barry, and he left the picture on her door . Then he says he will kill her and the girl he is going out with that night . Helen panics and locks herself in her bathroom; when Collie tries to take the door off its hinges, she breaks the bathroom window and jumps out . </P> <P> While Julie prepares to go out with Bud, her mother says she is worried and wants her to stay home, so she agrees, but when Bud arrives, he convinces her to at least walk him to his car so they can talk . He seems impatient, and she realizes she has never seen him so angry . She remembers the first moment she saw Ray when he returned from California, and she realizes she still has feelings for him . At his car, Bud reveals that he is Collingsworth Wilson, Daniel Gregg's half - brother, and he found out who had run him down by questioning the florist where Julie had bought condolence flowers anonymously . He also explains that Collie and Bud are, in fact, the same person . Bud begins strangling Julie and as she is at the point of unconsciousness, Ray appears and beats Bud / Collie unconscious with a flashlight . When the paramedics come, Bud is arrested for attempted murder . They tell Julie and Ray about Helen's accident and how she had sent them to Julie's house because there would be an attempt on her life . When Julie asked Ray how he knew of Bud's intentions, he tells her Barry called him to release him from the pact, and later he realized who Bud was . Then Julie asks Ray why Bud never tried to hurt him, and Ray answers: "He did, tonight . He knew the worst thing for me would be to stay alive in a world without you ." </P>
