Lou often calls Nolan 'cold' or 'imperfect' because of his different colored eyes and his hair with a green streak (from birth) and honestly, he doesn't care, even though he secretly likes Nolan.

Lou was walking through the school's mailroom when he heard a student bullying Nolan, calling him ugly and imperfect, which irritated Lou.

He went up to this person and touched his shoulder, with an irritated smile on his face. "I'm sorry, what did you call him?"
