While Hiccup tries to decide if it's time to leave Berk for good to keep the dragons and villagers safe, Toothless has something (or someone) else on this mind. As soon as he meets the Light Fury, a dragon with glimmering white scales and amazing abilities, she is never far from his thoughts"--Flyleaf.
