Sylvia's mother is named Dorothy, and her species is called Zbornak; this is a logical reference to The Golden Girls, which refers to the protagonist Dorothy Zbornak. In addition, Sylvia calls her mother "Ma", which is how Dorothy calls her mother Sophia Petrillo on the show.
This is another moment that points out Wander is homeless; when asked by Sylvia's where he lives, Wander's response is, "Wherever the stars take us."
This is the second episode to show Wander's vegetarian status, as when Sylvia's brothers chow down on meat, Wander requests for a salad instead.
