Mr. Cosplay
The spectacular actor has arrived! Trying to set the tone and re-create the scene is a great approach to give a historical lesson. This instructor happened to have a knight outfit on, giving lectures on medieval history while wearing it. This may be one method of gaining his attention.
We’re intrigued as to whether he has a costume for when he’s presenting other periods. This implies that this instructor is interested in acting, which may be hidden from his students. Perhaps he can join the drama department, regardless of his interests.
