He's a minor character, I wouldn't be suprised if you forgot him. He's a bouncy, eagar SandWing student at JMA, and he seems pretty nice. When Ostrich and Onyx went missing in book 10, Sunny called for his help.
I was thinking maybe... Mightyclaws? Because it seemed that he also suffered from a trauma due to his experiences on the vulcano and maybe they could comfort and heal each other? But Pronghorn would be great too, or maybe his clawmate, Peregrine, the SkyWing who is deaf on one ear.
Personally I prefer Sorawatcher because the image of Moon comforting Sora over her inner demons would be adorable, and they already showed signs of getting along well...of course I'd rather have Sora have help with her mental health first, as she's unstable and needs actual help instead of romance.
