Over time, he comes to warm to Norma, but often finds himself having to clean up her messes, including murdering a man threatening her, or pinning the blame for one of Norman's murders on somebody else . When a call girl staying at the motel gets shot and, upon dying, gives Norma a USB drive that contains a financial ledger splitting up an investment return of at least $15 million (illegal revenue from the drug trade), Romero must protect Norma, while investigating those listed on it, including his imprisoned father who used to be sheriff .
