The audience responds with enthusiastic applause as Elizabeth wraps up the show. In a spontaneous moment, Walter thinks of a fitting final line and displays it on a cue card: “This concludes your introduction to chemistry […] Class dismissed.” Elizabeth uses this line to end the episode, marking the conclusion of her journey on the show.
The audience's applause and Walter's impromptu cue card with the final line — “This concludes your introduction to chemistry […] Class dismissed”—serves as a fitting tribute to Elizabeth’s role as both an educator and a public figure. Previously, Elizabeth complained that Walter’s writing on the cue cards was terrible, and this scene shows that he has evolved as a result of working with her.
