Talk:Alyson May Castellan

Alice is her half-sister, not her stepsister. A stepsister is the child of one's stepmother or stepfather who is not one's half-sister, or the stepdaughter of one's mother or father who is not one's half-sister. A half-sister is a female with whom you share one parent instead of two. Allison's parents are Cayla and Luke, while Alice's parents are Thalia and Luke, so they're half-sisters. If Cayla had a daughter with another man, she would be Allison and Aphroditya's half-sister (half-brother if it was a boy) but have no relation to Alice. Make sense?
