Ahh no me neither, I didn't like the character at all. I always wondered why she was smiling at the very end. I wondered if it had something to do with Ivar and his future, maybe she saw the seer and knew what was upcoming for Ivar, she saw him becoming great. She might have visioned that Ivar will give Lagertha a brutal death... I dunno, I guess Aslaug was the one that knew Ivar the best, and meant the most to Ivar. Just a theory!
