The Ending Of Memory Explained
Alex follows Agent Serra and Beatriz from the detention center to the group home Beatriz was transferred to after the FBI secured a visa keeping her in the country. Agent Serra feels responsible for Beatriz, wanting to do what he can to help her after what she experienced in the sex-trafficking ring. Alex breaks into Beatriz's room to kill her, but when he sees her face, and Beatriz tells him she won't say anything, he leaves her alive.
After realizing she is a terrified teenager, Alex refuses to kill Beatriz, telling William Borden (Daniel De Bourg), his go-between with the client, to cancel the hit on Beatriz or Alex will kill Borden in retaliation. When Borden contacts the client, we learn she is a wealthy El Paso mogul who expects Borden to deal with the issue himself by calling Mexico City where they ordered the hit.
We don't initially understand why Alex, a contract killer, has such a powerful reaction to the contract on Beatriz's head, but later in the film, we will learn Alex and his brother were victims of child abuse at the hands of their father. Just because he is a contract killer doesn't mean Alex doesn't have a moral compass. He draws the line at hurting children.
