By the way, every single use of French in this fanfic was wrong.

French is a Romance language spoken in France and the Canadian province of Quebec, having accumulated around 70 million L1 speakers and 50 million L2 speakers. It makes appearances in MarrissaTheWriter fanfics, particularly those written by ASBusinessMagnet, seeing as she began learning French at about the same time when she started writing Post-SCrash Session 3: Spectators of the Host.
Sue Mary's story Love in Dead Space ends with the words "LE FIN", commenting that "(THATS A FRENSH END WARD TO MAKE IT SUND MORE ROMANTAC)".
Proper French, as spoken by a character, first appears in Post-SCrash Session 3: Spectators of the Host. Aranna Sorket, Skepness Man and Mr. Lewis have all, independently from each other, learned French, and all of them randomly spice up their English with French words and phrases. However, Skepness Man notes that speakers of French (and foreign languages in general, barring differently corrupted versions of English) are virtually nonexistent, and all French speakers in the fanfics so far have been shown to have contact with universes other than the Marrissaverse.
Liudas Vasaris is also shown to have knowledge of French; however, he doesn't speak English and as such does not mix in other languages into his French.
