Jeffrey is a very talkative and flippant man with a genuine and carefree nature. He conducts himself neatly and properly in public, but in private he acts lazy and unreliable, and says ridiculous things. Despite being outwardly nonchalant, he's very intelligent, cunning, and hard to read. He'll do all that he can to protect his loved ones, and he's obsessed with his younger brothers to an almost perverted degree. He's good with magic and disguises, and has a lot of connections.
