Dr. Lowe has glasses. His sight is so bad that he has an overactive sense of hearing, so he was able to hear Cookie sneaking out of study hall.
Dr. Lowe is a quirky and caring character. When someone is in distress he rushes to help them. He was almost killed by Christine the Saw and has many doctor's degrees. Aside from school psychiatrist and study hall teacher, it appeared Dr. Lowe was a bus driver in "The Late Bus".
