Neville has his back toward where the dragon was coming from so he saw Dan’s reaction before he realized what was going on. He turned to look and quickly shouted, “Ruby, no!”
The dragon stopped in its tracks and awkwardly plopped itself down to a sort-of sitting position. Neville put a hand on one of his shanks to make sure he stay still while he took a step toward Dan, putting himself sort-of between the two. “I’m so sorry.” he apologized quickly, “He didn’t mean to scare you, he just gets uh….enthusiastic.” he finished, a little lamely, realizing it wasn't much of an excuse.
