There are many references to the story of Peter Pan, including the names of the characters: Peter (Peter Pan), Big John (John Darling), Miguel (Michael Darling), Lily (Tiger Lily), Warden Hooke (Captain James Hook), and Wendy Henley (Wendy Darling). Other references are needing medicine, wanting a mother, asking mother to tell them a story that is long and with fighting, that "Mother" sleeps next to one of the children, and even the fact that each of the Lost Boys in Peter Pan wears a different animal pelt, which each of the children emulated in their respective woges, Lily - Fox, John - Rhino, Miguel - Bear, and Peter - Dog.
This episode opens with a quote from Peter Pan, "I think I had a mother once."
The wesen name Apgadnieks actually refers to someone who provides for others like a guardian or a family member.
As Nick and Adalind drive into garage of the new house/hide-out, you can see Juliette's Subaru parked inside. Nick apparently appropriated Juliette's car (and sold her house) after the character was killed off.
