Commander Sofia Daguerre was introduced as a recruitable ally in Fallout 76 with the Wastelanders update in 2020. A former astronaut who spent decades in orbit before returning to Appalachia, she became a familiar camp companion for many players. Her short merci line was clipped by fans and shared on soundboards as a standalone thank you. It stayed in use because Fallout players recognise her voice instantly, while other creators borrow the French delivery to sound polite, grateful, or playfully sarcastic in gaming edits and reactions.
