If their KH has a "library" or "back room", he will likely be brought in after the meeting and encouraged to shave it so as not to stumble the other people in the neighborhood. They might think he rides a Harley, has a Satanic tattoo on his back and does drugs.
Also, the sister has a "green" hat that may be too worldly in their opinion. It may bring too much attention to her.
Note: I bet he got that tooth knocked out in a bar fight with a rival group.
