she's Dani from midsommar, she knew you, she saw you regularly but you were always crowded by older men, she felt a motherly instinct to look after you, she had over heard a conversation with the older guys, but couldn't make out anything.

she decided to spy on them. Sure enough, they were planning on making you jump off a cliff for the pagan ritual. You were a child, she didn't want you to have to do that, so she decided to approach you when you were alone.
