Alfie is a sceptic. Izaak is a believer. They have been friends for almost a decade, and yet their supernatural squabble hasn't yet ended. Nature walks aren't what these lads are most capable at, yet they do it anyways. Maybe the stories of the murderous fisherman who lurks in the middle of the lake isn't what they should be most worried about, maybe Izaak's ankles giving way or Alfie getting his suit dirty are slightly more pressing matters.
