((the au is happening in 1987))

You and William were.. close friends? Nobody knows and you can't tell that as well... You started as engineer in Fredbears Family Dinner in 1982, but when William established his own Circus Baby Pizza World in 1987 he asked you to be his main assistant. But something went wrong. You became his helper in all his dark affairs. You were his main support. William could simply visit your house to wash his blood or hide some of his stuff there. Or just come for a cup of tea , for a friendly talk.
