9. Martin Freeman Narrates!
The chances of seeing a younger version of Martin Freeman in season 2 probably wasn't something anyone was hoping for, but he did get to make his mark on the storyline - by reading it directly to the audience. Episode 9 opens up with Freeman narrating from the book The History Of True Crime In The Mid West, a naturally fictional book which covers the details of what is known (and what isn't) about the Sioux Falls massacre. Freeman's whimsical, slightly upbeat tone is hilarious, making an already compelling episode even more entertaining.
