Either way, Gus fell asleep drunk behind the wheel after the breakup and drove upside down in a truck. He survived, but we’re supposed to find out he became addicted to fentanyl that was prescribed for him because of the pain. After Gus’ hospitalization, he became more addicted to drugs. Gus showed up at Howard’s house one night and asked Cassie specialto let him in. She did, and he stole some expensive goods to suppress his drug addiction. The marks on Gus’ arm suggest that he had turned to heroin. Cassie never saw Gus again, and she never told anyone what he did.
