Derek wasn't expecting his sister to be awake this early, much less in the woods chasing him. That was his excuse for Laura being able to pounce him from behind and tackle him to the forest floor.
He grunted at the impact and shoved her off of him with a sulk practiced by much-maligned little brothers everywhere. "What the hell, Laur?" he grumbled, turning over onto his back to catch his breath.
The wind sent another scent towards him and he raised an eyebrow as he sat up, looking past his sister at the female behind her. Suddenly, her being outside and beating up on him made sense. He huffed a laugh and rolled his eyes.
