As in the previous episode, as Claire is approaching the apothecary, in the distance Notre Dame Cathedral can be seen. Clearly visible is the spire added in the 19th century, which collapsed in the recent fire.
When Jamie first encounters Fergus stealing Fergus tells him that he doesn't steal all the time, "but, like" only when Maison Elise was busy. Using like as a filler word would not be done for about 200 years.
At the end of the previous season, Claire whispers the exact date of Jack Randal's death into his ear. Yet, in this episode, she assumes that he is dead, is surprised that he is alive, and then says that he must survive at least one more year so that he can sire Frank's direct ancestor.
