  • The episode takes its title from the Christian Feast of the Ascension, which celebrates Jesus Christ's ascent to Heaven. Traditionally celebrated on a Thursday, the fortieth day of Easter or following Sunday. Given that in 1896 Easter was celebrated April 5th, it marks the events of this episode around mid-May, 1896.
