Tyson is very close with his brother’s part of the family, regularly babysitting his nephew and going mountain boarding with his sister-in-law.
However, an artificial distance is imposed by Jethro to protect his family from The Colonel and Tyson’s involvement in the web. Tyson isn’t allowed to visit them up in Cumbria. His work comes nowhere near them. They meet with him in London, at an arranged holiday location, or at the family manor in Cambridge. Never in Cumbria.
Despite that Tyson regularly talks on the phone with Jethro, Rosie, & James. He knows what’s going on in their lives and they know a sanitised version of what is happening in his life.
He knows when James’s hatred of carrots has returned and when he’ll agree to eat them. Tyson can tell just by the tone of his voice how stressful Jethro’s work has been that week. He knows what workout routine Rosie is currently going through, and if she’s flip-flopped on spelling her name Rosie or Rosy; again.
Jethro sends his brother a care package every month, rightfully, not trusting him to take care of himself otherwise. Rosie always seems to know when Tyson needs a distraction and has the perfect story in her back pocket to take his mind away from the problem. James adores his nephew and secretly suspects that he’s a secret agent.
