This is the second episode this week of Don’t Trust The B— In Apartment 23, and after watching "The Scarlet Neighbor" and a few things not making any sort of sense to me, I did a bit of research and found out that this episode was actually supposed to air during the first season.
This makes a lot of sense as June is still doe eyed and naive, not to mention working at the coffee shop when in "Paris…" she had her job on Wall Street. Why the network decided to air this episode so amazingly out of order is beyond me, but it made for some very disjointed story telling.
In "The Scarlet Neighbor", June decides to school Chloe on the ways of having a monogamous relationship instead of just sex with random people. Unlike a previous episode of Don’t Trust The B—– In Apartment 23, June learns a lesson at the end of this one that she should not be judgmental about other people’s sex lives.
