I found out the identity of the new killer
The new killer will be...
Miss Trunchbull from Matilda. Yes, you heard me right. Hear me out.
1) Matilda is a 'classic'
2) The "bee", "sweet" refers to Miss Honey (Which is sweet) and how Her father called her his Bumblebee. The teaser was also black and gold. The colours of a bee.
3) They found files in the game relating to a teacher. Miss Trunchbull is a principal at her school and is known for her creative punishments.
4) She can break down walls, as demonstrated in the movie.
5) Miss Honey will be the new survivor.
6) She terrified the heck out of kids even though it was not a traditional horror movie.
There. No more need to debate.
