"Oh." Dilan blinked up at Nevada and smiled, "Yes, I know. But you're a pseudo-parental figure who is not actually a parent. Braig calls my momma Aunt Lenna, and we call Aya's dad Uncle Jerrig. I call Braig's parents mom and dad 'cause I don't have a father of my own and it'd be weird to call dad dad and mom Aunt Elcy. It's just local short-hand for adult male who is authorised to take us places and do things with us without having to check in with our assorted parental figures every time."
