Twilight and Shining's parents Twilight Velvet and Night Light were named after characters from the 1980s "My Little Pony" series. Twilight Velvet was based on Twilight from My Little Pony Tales (1992). Night Light was based on Nachtlicht, a character sold only in Germany (ironically, Nachtlicht was a female pony).
This is the first ever episode where Twilight's parents, Twilight Velvet and Night Light spoke.
Friendship Report: Twilight learned letting Starlight make her own decisions is the best way to teach from time to time.
