Technically you were Gerard and Mikeys little sister, your parents didn't plan on a third child but Gerard and Mikey wouldn't have had it another way, so when Ray and frank started coming around it was like your own little family, sense your parents weren't around a lot, so the four guy's were your parental figures, they were all over protective of you, you were still human because you were still to young to be turned but that meant they were very careful with you.
