I'm so excited. Yeah. They created all of these clocks for it. It's fun. It's a show -- I read the pilot. And I couldn't believe that abc wanted to do something this big. It's a really big story. The exciting part for me is we're telling the story over the next 13 episodes. What starts on television tomorrow is a big mystery that we're going to solve by may. You're not going to us along. You're going to give us a resolution to this mystery. And hopefully there will be these 13-episode arcs with a new mystery? As a result, we don't have have to hold back.
