Tommy giggled at being head-butted, and squirmed out of Tegan's grasp to chase after. Tegan knew it was a losing battle, with as much energy as Tommy had at the moment, and the dog, if she could call such a wolf-ish animal a dog, seemed to at least be friendly. It didn't completely settle her nerves, but she was able to simply bite her lip a bit and call after them a stern "Be careful!"
She sat on the grass, under the tree, and watched Tommy run and play. Smiling to herself, she took a few pictures of the two of them, the zoom of her lens able to get close enough to capture a few good shots.
