I wanted to pull back the curtain on how things were with them. We always knew Hanna did all the talking, and in some ways that suited Marek. Even now, she knows him so well. But knowing him and being right isn't enough. It might even be the opposite of what he needs. Marek has his own mistakes to make and his own successes to enjoy, and Hanna, by necessity, isn't part of that.
