Glaurung managed to dodge the first punch by craning her neck out of the way and shooting a successive ball of flame at her assailant. However that helped very little with the next punch which hit the dragon squarely in the jaw and sent her passenger sprawling forward onto the top of her head. The god in question, scrabbled for purchase and latched onto one of her horns and spewed forth a multitude of rude and insulting words in various languages.
The kick sends Glaurung toppling into a near building, the motion of which sent Loki flying onto the rooftop, which began crumbling as the dragon moved to get up. Swearing once more Loki teleported himself to the top of her head and hissed in anger. Within moments the god and dragon where up in the air, looming over the giantess. Only then did Loki amplify his voice to speak to her. "It is rather rude -is it not?- to jump in to a situation without introducing oneself first." His deep British sounding tones filled the air.
