Everything Carries Sound - Episode 5

At a gala, Luna — identified as Mr. Porter/Sean's deaf-mute girlfriend — arrives amid whispers and awkward suggestions to learn sign language. June approaches, begins to introduce herself as "Sean's..." then, realizing Luna can't hear or speak, blurts "you're mute and deaf." Sean, embarrassed, tells Luna to cool off and pleads she not embarrass him, while reminding June he promised her the first dance. Luna insists she wants to socialize and asks to talk, but others stall her. The episode ends with Sean torn between his public promise and Luna's request, leaving the dance and their talk unresolved.
