Throughout Treason
Adam goes to Callum's school to talk about his career in the MI6.

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.
