Do you think Korra will ever find out about (SPOILERS)

Tarrlok's sacrifice? And if not his sacrifice then at least knowing they were both killed? I really hope she does because as far as she knows, there is still a crazy bloodbender out there who can take bending away and isn't remorseful of what he's done. I'm not sure how far away they were when it happened but I hope that someone finds the remains of the boat and Korra finds out. What are your thoughts?
