@EllieArella good question it can get confused especially bc i don’t tend to talk abt it much but they’re not related to her ! zera called leia her sister bc that’s how she sees her for ten years that little girl is all zera has known and she means the world to her but that’s it she’s her sister in name and nothing else and with luke still not related but they have a connection in the sense that his parents looked after her for a few years !!
