Harry manages to save Seraphina through a favor from a mysterious character, Kat McAllister. Janet McTeer plays the role of Kat, who seems to be an influential personality in the crime world. Although not revealed completely, it seems she has a stronger hold over all the crime groups and families shown in the series.
All about Kat McAllister, who Harry calls in MobLand

In the latter part of the episode, there is a scene featuring Jaime Lopez and the kidnapped Seraphina and Brendan Harrigan. The Mexican crime cartel leader expresses his hatred for Conrad, who insulted his father around 30 years ago with derogatory remarks.
While Seraphina makes 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 is shared with Conrad, Maeve (Helen Mirren), and Kevin by Richie, in which Seraphina and Brendan are shown being tortured. As the family watches Brendan get tortured by a chainsaw, finally succumbing to his death, Harry makes 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 starts with the latter insisting that he had been avoiding her. The tone of their conversation suggests a connection and a significant past between the characters. Harry then asks for an urgent favor to save the sibling duo.
Kat McAllister comes to the rescue in MobLand episode 7

The high-profile mysterious character answers Harry's call while travelling on her private jet. When Harry asks her for a 'big favor,' she readily agrees to help him out. Harry requests that she stop Jaime from killing the Harrigan siblings.
In a parallel scene from the episode, it is shown that Jaime receives a call from her while Brendan is being killed. During the call, Jaime informs Kat that she was a little late, as Brendan had already died. She then convinces him to leave Seraphina, which he complies with readily.
She manages to stop Jaime with just a phone call, showing the power she wields in the crime world.
With Kat's help, Harry is able to save Seraphina, but Brendan dies. Kat calls Harry again, and the latter thanks her for the help. The episode ends with Kat telling Harry that he owes her, indicating a significant role that this character will take in the further episodes of MobLand.
The next episodes may unravel more details about Kat McAllister, her relationship with Harry, and what her character will bring to the story of the Harrigans in the series.
