In "The Persistence of Memory," Bay is haunted by an old photo of a pregnant Regina and asks Emmett to help her find her biological father. With Emmett's assistance, the two manage to find his car in an abandoned junkyard, but just as Bay is about to give up, she notices a guitar pick that leads her one step closer to finding her father. Meanwhile, Daphne enrolls in the advanced cooking class at Buckner Hall where she soon realizes their kitchen does not cater to deaf people. After feeling embarrassed by an accident while in class, Daphne almost gets hit by a car, causing her to think for the first time that a cochlear implant might be a good idea. Meanwhile, Toby gets himself further into trouble when he conspires with Wilke to break into the school to steal a test.
