Mrs. Hoida is an English and Literature teacher at Blackwell Academy. She is currently absent due to a severe depression. She was still at Blackwell in September when Max Caulfield began attending the school. It's assumed that Nathan Prescott's disruptive behavior had something to do with her absence, as he had at least one crude outburst in Mrs. Hoida's Intro to Literature class on September 17, which is evident through an incident report file from Principal Wells' office.
Mrs. Hoida is mentioned once in "Out of Time" when Max is looking at her class schedule.
It's speculated that Mrs. Hoida could have known something about the Dark Room Conspiracy.
