Complete story — includes the ending
In a flashback, Shane genuinely attempts to rescue Rick from the hospital but mistakenly presumes him dead and flees. In the present, Shane gets drunk and tries to explain this to Lori, but sexually assaults her when she resists. The group enters the CDC and meet Dr. Edwin Jenner, the only scientist left. Jenner reveals the brain scan of an infected patient, dubbed TS-19, showing the disease to be incurable. Jenner locks the group inside and reveals that the building will self-detonate. After losing his wife, the subject of the brain scan, Jenner nihilistically believes that suicide is best. Rick learns a secret from Jenner and persuades him to let them escape. Andrea and Jacqui stay behind but Dale convinces Andrea to leave with him. Jenner and Jacqui await a painless death while Rick leads the group on.
