I have recently fallen completely and utterly in love with the German series on amazon prime called Maxton Hall: The World Between Us / Die Welt zwischen uns. If you haven't watched it, you need to watch it but watch it in its original German with the English subtitles because you will lose so much with the English dub. Anyway, I looooooooooooooooooooooove James and Ruby so much. It's almost terrifying how much I love them as a ship.
Spoilers for all season 1. The song is La Plus Belle pour aller danser a French song from the sixties sung by Sylvie Vartan. I used it because part of the reason I love Ruby and James so much is that when they are not at one another's throats, they have a playful, puckish relationship that reminds me of the old screwball comedies. I LOVE it so much....!!!
