Tails kind of noticed himself turning into a human as he entered the nightmare, but didn't pay any mind to it as he rushed to his friend's side. He would've called out her name again before getting near, but that didn't seem like a wise decision given the fact her and Hiccup's assailant was probably still nearby. As he got over to her, he tried to talk, but the only word that could come out of his mouth was: "Fluttershy..." It was an awful sight.
