The scene on the beach where Maddy meets the "40 year old guy in Panama City Beach" is a thinly veiled nod to Stanley Kubrick's 1962 film "Lolita (1962)" - when the film's protagonist meets Lolita in the film, she's out back sunbathing with the same sunglasses Maddy has on.
The character of Minako is a reference to Minako Aino/Sailor Venus from 'Sailor Moon (1995)'. They claim to be from Venus and perform a little tease with a chain necklace in a similar fashion to Sailor Venus' "Venus Love Me Chain" attack. The anime Sailor Moon is referenced in the very first episode by claiming that Jules "showed up looking all Sailor Moon"
The episode is filmed under the working title, "Trace Decay", which is referenced to Westworld (2016).
