In this recap of episode 2 of HBO Max's The Staircase, "Chiroptera", Gretchen and Dennis continue to detail the events of Kathleen Peterson's death and the events that followed, as depicted in the dramatised version, as well as sharing the wealth of knowledge that they have amassed from other sources since their fascination with the case began. It's becoming abundantly clear that they both have opinions on the case and it might come as no surprise that their opinions are not the same.
