It all started when Henry Emily and William Afton started Freddy & Friends in '73. 10 years later in 1983 Y/n's younger sister, Charlotte Emily, "mysteriously" died. Y/n and Michael bonded over the death of their siblings. Y/n doesn't want to have anything to do with the Freddy Franchise that her and Michaels dad made, but she's still witnessing every traumatic thing within this franchise, even up to Michaels death.
