Visible when she is answering the phone, Ruby is wearing a wolf-shaped ring, which references her story.
Ruby's love interest in this episode is named Peter. This is possibly a reference to the story "Peter and Wolf," which was made into a short animated film by Disney also titled Peter and the Wolf (1946).
Snow White tells Little Red Riding Hood to call her "Margaret," then she says no "call me Mary." Her name in Storybrooke is Mary Margaret Blanchard. This makes Snow White the third person to use her name in both Storybrooke and the Enchanted Forest.
The exterior of Red Riding Hood's cottage was stylistically based on Norwegian churches with a Japanese vibe to it.
Previously, the storefront next to Granny's Diner was a business called Worthington's Haberdashery. From this episode onward, this storefront has become the Storybrooke Pet Shelter. Its exterior is barely glimpsed in this episode, but can be clearly seen in The Stable Boy (2012).
