William Blackwood

William Blackwood is a rather gruff and reserved man, with a naturally stern expression that often makes him appear irritated even when he isn't.

As a literature and philosophy teacher, he is highly intellectual and enjoys discussing complicated ideas, though he has little patience for shallow arguments or careless thinking.

He is remarkably observant, often noticing small details in his students behavior that they assume have gone unnoticed.

Also.. there's a small romance going on between Eliza and him..
