Femradiel had no idea how much Ryan actually learned after the failure. Still, she concluded it hadn't been much since he spent the entire day doing nothing and just stayed in the same place he had been when he attacked the Hydra.
The truth is, Ryan didn't spend the day doing nothing. Femradiel just didn't know what he had done. After sunset, Ryan approached the ocean, then suddenly and out of nowhere, something jumped from the completely dark ocean. Even Femradiel didn't notice the Hydra's approach, but Ryan did. Despite that, the Hydra approached faster than he could escape with Teleport and ate him as a whole.
"HHUUUUUUUUUUAAAAAAAAAARREERRGGGGGGGGHHHH."
