So, Riley was...Bonded to the girl upon Corr's back? A powerful magic linked her to Ravenna? She...Accepted that explanation. It cleared up how she knew the human female's name without ever having met her. And why she desperately pulled the girl off of the piebald's back when it appeared she would drown. It quickly dawned upon the white mare how she had injured her very companion with this rescue. "I'm deeply sorry. I feared she would drown if I didn't act." and Riley had not wanted to lose one she had been drawn to.
Should the water horse have fought the bond? It was to be expected. But Riley went against this. She saw very few reason to. She would stay upon the island for the girl and the girl only. Which meant if Ravenna ever chose to leave, Riley would try her hardest to accompany her. It merely seemed pointless to fight magic. And on another note, she felt obligated to protect such a fragile creature. "I must admit, though...She shows great bravery."
Yes. A great amount of bravery for one who could've been torn to shreds. Riley found that an interesting quality in her apparent 'rider.' She herself was more than willing to fight creatures bigger than her, in the right setting.
