That news about the powers being gone isn't news to Raiden, but the general knowledge that this is the effect of the realm on others is a surprise. His shoulders pull back a little at that revelation, but not out of wariness.

"I noticed. It's not the first realm to have that effect, but at least it's not just me. I would be honored to learn the art of Bending from you." Learning? To use magic? It was a fantastically weird concept to Raiden but he was willing to go along if it restored something of his normal self. It was unnerving to feel so completely normal and human.
