In the latter part of the episode, a detailed scene of Jaime Lopez and the kidnapped Seraphina and Brendan Harrigan unfolds. The Mexican crime cartel leader expressed his hatred for Conrad, who insulted his father around 30 years ago with derogatory remarks.

While Seraphina made earnest efforts to negotiate with him through monetary offers and an apology from her father, Jaime doesn't budge from his plan as instructed by Richie Stevenson.

A live stream link was shared with Conrad, Maeve (Helen Mirren), and Kevin by Richie, in which Seraphina and Brendan were shown being tortured to death to their family. As the family watched Brendan get tortured by a chainsaw, finally succumbing to death, Harry made an urgent call to an unknown character called Kat McAllister.

While the call is shown briefly towards the end, the conversation between Harry and Kat McAllister started with the latter insisting that he had been avoiding her. Their tone of conversation suggests a connection and a significant past between the characters. It is then that Harry asked for an urgent favor to save the duo.

The high-profile mysterious character received Harry's call while travelling on her private jet. When Harry asked her for a 'big favor', she readily agreed to help him out. Harry asked her to stop Jaime from killing the Harrigan siblings.

In a parallel scene from the episode, it is shown that Jaime received a call from her while Brendan was being killed. During the call, Jaime informed Kat that she was a little late, as Brendan had died. She convinced him to leave Seraphina, which he complied with readily.

She managed to stop Jaime with just a phone call, showing her upper hand in the entire situation and reflecting her powerful stature in the crime world.

With Kat's help, Harry is able to save Seraphina, but Brendan dies in the incident. As the episode ended on this scene, Kat called Harry again, and the latter thanked her for the help. The episode ended with Kat telling Harry that he owed her, indicating a significant role that this character will take in the further episodes of MobLand.

The next episodes may further unravel more details about Kat McAllister, her relationship with Harry, and what her character will bring to the story of Harrigans in the series.
