School 5 (flashback)

Mr Cwesschyn is the principal of Riddle Elementary School and is the first person Phil takes a key from the room of nate.

He could possibly a counselor too, given that in Riddle School 2, Phil bets that "the counselor at this school has the keys like last time" (italics added for emphasis).

According to Riddle School 4, Mr Cwesschyn was put to jail for life because he physically beat a student's head in. However, this cannot be true because RS4 is just a dream.
