Zacharie had woken to see a littermate missing, and decided to take it upon himself to track them down. Sneaking past the sleeping adults (Saga, if no one else, almost certainly would have spotted him, but he chose to believe in the power of his own stalk regardless), he eventually spotted Ottilie. Filthy and with back turned!
Grinning, Zacharie did his best to get close without being heard, but the patience of a pup was not well developed at this age, and he soon decided a bellowing charge would be more fun. With a loud bark, he pounced! He would bite her if he could! Hard!
But
Eugh!What had she rolled in?
Ottilie, tu pues!Papa would be upset!
I love IC spontaneity & drama! So if it's what your character would do, let 'em attempt it!
My characters are unreliable narrators.
