The "interests" listed on Dean's dating app, "Rolling through town, no strings attached.

The title of the episode was originally 'Let her go' but was changed because it was too reminiscent of Disney's Frozen (2013).
Elysia Rotaru (Shaylene) previously appeared in the episode Of Grave Importance (2012) as "Victoria Dodd".
