Why Does Perry Follow Kathleen?

There's something interesting with the two of them, like parents that have certain knowledge and decide when do we withhold information from our kids? And when do we lie to them? When do we tell them the truth? Which is also a theme that will keep coming up in this show. It was important for us for the audience to wonder why? Why is he following her? What is so compelling there? All I can tell you is keep watching the show.
