Unmarked spoilers are ahead, per Spoilers Off rule.
The lengthy and extremely graphic rape and murder scene, filmed from the perpetrator's point of view. Adding to the depravity is that the rapist puts a connecting SQUID recorder on his victim so she can see her own rape and murder and experience her rapist/murderer’s pleasure at what he was doing. Lenny is so horrified by the memory that he projectile vomits in the aftermath.
