With her young nephew in tow, the two headed towards the nearest stream. Snow could have worked for this just as easily but Lyra didn't trust it not to have anything in there that might irritate the area where Osiris' tooth had once been. No, the clean waters of a river would suffice — the coldness would help numb the area, too.

Osiris was oddly silent for a while as they travelled, until suddenly he made an unexpected comment that coaxed a huff of amusement out of Lyra. "That's right," she said, turning to meet his inquisitive gaze. "Those are your baby teeth, they eventually fall out to make way for your adult teeth." At this, the woman bared her fangs in a grin, pleased with how her own set had served her thus far in her life. "Your new ones will be bigger, sturdier, made for tearing meat from kills." And your enemies.

She slowed as they came upon the stream, dipping her head to take a drink before gently saying, "the process of growing in your adult teeth will be painful, though."
