Hubris - It's unfortunate that he is disgusting...

"Agatha fainted; and Safie, unable to attend to her friend, rushed out of the cottage." (Page 96-97)

     This is a slightly depressing scene to think about. The creature spends about a year spying on the DeLaceys and blows it in about 5 minutes. He gets the old, blind father to be supportive of him for all of about 10 minutes, and then his looks fail him, and he is feared once again. So, I've decided his hubris is how deformed and frightful he looks. The poor guy can't catch a break, and his physical appearance leads to his lack of a woman and self-esteem which leads to his eventual demise. It all connects to his spooky appearance. Oh darn. I searched google images for the scariest and most accurate version of the creature I could find. I like this one best:

Imagine coming home to that!! And sitting next to your kind, old father. Tsk tsk. Like good ole Mrs. Bennett says in Pride and Prejudice, "tis a shame [he's] not more handsome."
