Yeah right, liar. Satu didn't believe for a second that Leif would really not read her mind if he could turn it off. Just like Jokull wouldn't have. Telepaths weren't really the sort of person you could trust to stay out of your head. Twelve and Satu was already totally aware of how true that was. "Aw look, you remembered your manners." She wasn't trying to be rude. It was just something she'd heard her mother remarking on. Leif could apparently be as perfectly polite as them when he chose to be. He just didn't seem to be able to use them when it came to the family. For some weird reason.
"I'm twelve, don't think I need to worry about sacrificing just yet." The idea should bother her more. Leif had killed someone for his magic. 'You don't have to... be a master water!' "But yeah. Blood magic. You'll teach me without telling mom." Really big point. Leif had to not tell their mother. Satu so many levels of didn't want her to know.
