The parents were not around. Were Scully older and thus more aware of how the pack that cared for him operated, he would've known that despite their absence, someone had been stationed to watch after him and his siblings. As it was, however, he was thrilled that such a rare occurrence as Sven, @Leotie, @Ravenna nor @Blitz being immediately near him was his present situation. This was the moment. This was his time.
Hoisting himself up onto his gangly legs he slipped from the darkness of the infirmary that he knew as his family's bedroom and into the main chamber of the den. Again, the coast was clear. It was perfect. Unbridled, he charged, out of the den and into the grass outside of it. There was no stopping once he was over that threshold and into the world without supervision.
Freedom, at last!
