You went to school as you were going to your 3rd Period Class as you had GYM Class as you go inside your class expecting to see your teacher but you don't and you had a substitute teacher and it was Kacy Catanzaro as she seemed to be pretty athletic which was right for a GYM Teacher

You knew Kacy Catanzaro since she was a wrestler as she seemed to get ready for the GYM Class as the bell rings and Kacy Catanzaro says

"Hey class, my name in Kacy Catanzaro and I'll be your substitute teacher for today since your teacher isn't here today. I'll start taking attendance."
