Dope Thief Season 1 finale ending explained
The show follows two close friends, Manny and Ray, who decide to pose as DEA agents and seize drugs, only to resell them. The episode progresses with Ray visiting his estranged father, Bart, in prison. Moreover, one of the big twists that come to light in the finale is that Bill McKinty, the head of the DEA’s Boston office, was secretly running The Alliance in Dope Thief.
The Alliance is basically a third party hired by the cartel for shipment and transportation. Once a location is in the system of the DEA, no one raids it, because it is assumed to be an active investigation under surveillance.
McKinty exploited this by listing drug houses and meth labs used by the cartel, giving them full protection from law enforcement while making it look like they were being watched. This is also how Manny and Ray's impersonation got caught as they started raiding the protected areas of the cartel, bringing them both under the cartel's and the DEA's radar.
Mina and Ray bond over shared loss and grief in the Dope Thief finale

Mina initially believes Ray is just another hustler caught in the drug game. But once she meets him, she sees something familiar. Mina was in a similar situation when she lost her partner, like how Ray feels after losing his best friend. This leads to them bonding over shared grief and trauma. The mutual grief creates trust between them, and by the finale, Mina recognises that Ray is not the big fish but someone who is being used by a mastermind.
The fire probably allows Mina and Ray to start life anew by faking their deaths and disappearing. Marchetti, meanwhile, possesses full knowledge of the situation, and can ensure that the database is not misused further. They might investigate some more dealers connected with McKinty.
If Ray resumes his normal life, he could face imprisonment while being an agent, but Mina could solve more cases related to drug dealing. There is, however, the threat of cartel members chasing them down. Therefore, it is better for them to be in hiding for a while in Dope Thief.
