The forest river location where Arthur and Elena ride for their picnic appears to be the same location where Morgana and Gwen attempt to escape their kidnappers in Lancelot and Guinevere (2009)
Two of the actors in this episode have connections to the city of Exeter in Devon: Bradley James (Arthur) was born there, while Georgia King (Princess Elena), although Scottish, went to "Exeter School", which is a private school in the city.
Arthur mentions needing the strength and support of the woman he loves to be able to rule Camelot , this is very similar to what Edward said about Wallace Simpson when he abdicated the throne in order to marry her .
