The episode tugs at the heartstrings with the subtlety of a bell-ringer, and somehow it still works. Somewhere a prop department is very proud of the father. The flashbacks are back, like an uncle who tells the same story at every dinner. A thread left dangling since S04E04 gets tied off at last, neatly enough to make a librarian smile. "Roxenburg. Definitely no one who would name me in their will." sounds simple, which is exactly why it is unsettling. An episode that makes the whole series look good.
