The line of the week goes to "But why did you suddenly start studying?", which deserves to be embroidered on a cushion. Clues pile up faster than anyone can label them, and Amon looks like the only person who brought a filing cabinet. Amon joins the cast and immediately looks like trouble. It does not quite match E01; think of it as that episode's tired cousin. Read a summary instead; it is shorter and has the same feelings.
