This episode opens with a quote from Shakespeare's Julius Caesar. "The evil that men do lives after them; The good is oft interred with their bones."
The blue food truck that hits Charlie has the sign "Porklandia" on the side. Porklandia is an annual festival celebration of "All thing Pork" hosted by Carlton, Oregon, approximately 36 miles southwest of Portland. Porklandia is a pun on Portlandia which is the name of the statue depicting the female figure on the Portland City Seal. The statue of Portlandia is the second largest bronze statue in the USA after the statute of Liberty. The poem dedicating the statue, and also titled "Portlandia," reads: "She kneels down, and from the quietness of copper reaches out. We take that stillness into ourselves, and somewhere deep in the earth our breath becomes her city. If she could speak this is what she would say: Follow that breath. Home is the journey we make. This is how the world knows where we are."
Echoing the sentiment of the Portlandia poem, a few minutes earlier before he was hit by the truck, Charlie shouted to himself "You know how they say you can't go home again? I don't want to go home again."
The number of Zuri's home address, 518, is a reference to the episode number.
Rosalee says that Adalind has had her powers back "maybe three or four weeks;" depending on how she's calculating this (whether she thinks the occurrence in the Spice Shop was the first time, or that her powers had come back before then, or that this was an early sign but her powers didn't really come back until later), this puts the events of "Into the Schwarzwald" and the episodes on either side of it at approximately the same time frame--three or four weeks before this episode.
Paul Root, who portrays Pinklon "Pinky" Williams, also portrayed Michael Patterson in Big Feet (2012).
