 Seba Nile served as a big inspiration to Mr. Crepsley (while teaching Mr. Crepsley, before the series, he says he wishes to speak like Seba.Seba takes the matter further by plucking a hair from inside of Mr. Crepsley's nose whenever he said 
can't or won't or it's).Seba also dresses all in red, which is where Mr. Crepsley got the idea.
