Nick offers Morgan part of a peanut butter protein bar, which is a nod to Michonne stealing one of Morgan's peanut butter protein bars during the Clear episode of The Walking Dead.
Garret Dillahunt stated on Instagram that Danay Garcia and him had to dub their conversation while walking down the road in post-production because the approach of Althea's SWAT truck overpowered their dialogue lines.
In this episode Nick finds something "Good Out Here" in a patch of bluebonnets, which are the state flower of Texas. Madison had once told Nick that she copes with going out of their safety zone by always looking for something good while she's out.
Nick and Morgan are wearing coats and are able to see their breath. In Texas, that is normally only possible until March at the very latest, which is too early for this episode's featured flower, the Bluebonnet, which blooms late March and dies off in late May.
