JJ cons people into doing things he wants by saying, "I'm Canadian, you can trust me."

he duped Seunggil Lee onto the ice only to be lifted into the air suddenly from behind and spun around. (seung promptly used his fighting skills to not only get down but to almost break JJ's nose.)

he also may or may not have slightly molested yurio in a closet under the pretense that he had a box of kittens.
