Derek tells Paula that his prospective buyer is "probably some gawking wasichu". "Wasichu" is Sioux for "non-Indian". Some people say that "wasichu" means "greedy person" or "one who steals the fat" but those translations belong to "wasin icu", which is similar but not the same as "wasichu" in the same way that "manger" is not the same as "manager".
In a scene taking place in the support group, Kaia calls Jack "Suite Life". This is a reference to the popular Disney Channel show The Suite Life of Zack & Cody (2005) which is about identical twins who live at a fancy hotel with their mother, who works in the hotel lounge as a singer; Jack does resemble the two main characters, in both appearance and demeanor. "Supernatural" recurring guest star Kim Rhodes played the mother of the twin boys.
