Pretty Girl is a woman Shawn meets at a speed-dating event while undercover during an investigation. He shoos away a boring guy to sit opposite her, for which she is grateful. She thinks Shawn is cute and starts telling him about her volunteer work for an animal shelter, but Shawn has just solved the case and promises to get back to her after outing Marvin and Glenda as the culprits.
When he's done, Pretty Girl tells him how she likes beagles and sometimes puts little sweaters on them. However, Juliet then cuts in to tell Shawn how she doesn't want things to be awkward between them after their 100% match on the speed-dating questionnaire, and it's unknown whether Shawn ever pursues Pretty Girl any further.
