This was certainly unexpected and definitely not welcome in her household. Gina Winchester left her family to escape all the fighting, all the hunting and all the "John Winchester is all holier than thou". Yet four years after she left, four years after she got into the University of San Fransisco, four years after she made her own home and her own friends and family, her older brother turns up out of the blue, with their youngest by his side. After some hassle, she agrees to leave her life behind for a few days but comes back to another surprise, and it's worse than the first one.
