Throughout Treason
Sir Martin Angelis is poisoned by Kara Yerzova, who is Adam Lawrence's ex-lover and a former Russian spy.

While Martin is in hospital, Adam goes to his house to get a file about Audrey Gratz, which he passes to Kara Yerzova. When searching for files, Adam comes across a file about himself. CIA was suspicious that Adam had been compromised, due to his intel on the planned attack.

After Adam learns that the CIA was behind Ella's kidnapping, and that his wife, Maddy De Costa, is in contact with Dede Alexander, he moves out and takes his kids to Martin's house. He tells Martin's wife, Mary, that he and Maddy fought, so they needed a place to stay. While Mary is distracted playing piano with the kids, Kara sneaks around the basement searching for a file about Baku, as she needs to know who killed the 5 men who worked for her in Baku. She had promised these men safety, so she owed it to their families to tell them who had killed them.

When Martin returns home from the hospital, he confronts Adam regarding his relationship with Kara. He shows him a file, and tells Adam he will be going to jail.
