While Trevor pitches the snatch-and-run job to Riley as a problem solver, hindsight shows he would've actually cared a lot more if it was a legit burglary, as Riley was led to believe. To begin with, Trevor breaks into the warehouse, not wearing gloves and leaving him open to getting linked to the crime. To make matters worse, he's drinking on the job, leaving a beer bottle that screams "DNA," and quickly lining him up with the break-in as well.
Of course, that would all be an issue if it was ever brought to the attention of the police, but leave it to the owner, Roland to brush that all aside in the hope of regaining some nerves. Instead, Riley has a hell of a time getting the Cenobites and its prickly-headed leader off her back before she rips the skin from it. Ultimately, justice is brutally served when Trevor receives the necessary treatment, proving, as always, that men are no good when it comes to inter-dimensional gateways to hellish realms run by demonic gatekeepers.
