Added to Personality:

He drinks peppermint herbal tea, eats peppermint candies, and has been know to chew on raw peppermint leaves. Even the smell is intoxicating to him. He actually dips vegetables into his tea to soak up a little peppermint flavor. It's not clear where this love of peppermint comes from, it's just been gradually building up to an extreme.
