Her cares on his safety -- whatever they are -- are neither here nor there. She'll be damned if she's getting a ticket because her little brother hasn't buckled up. So the seatbelt is managed on his behalf.

She thanks Principal Morehead for all his kind help, again (this does not need to wind up in the tabloids), and keeps her concerned big sister act going all the way to the edge of the parking lot.

At which point, she turns the radio up loud enough to discourage conversation and heads for her father's house.
