With the ice dragons backing off, the others have gone hunting, leaving Avery and Tobit home alone. They're the smallest members of the clan, and the weakest, but that has never bothered Tobit. He just wants everyone to be safe and happy, and he does whatever he can to make that happen. And now that he has some alone time with Avery, he knows it's his chance to get close to the other dragon.
Avery doesn't understand what it means to completely belong to the clan, not yet at least, and what Tobit describes to him is different than anything he's ever considered before. With Tobit there to guide him, they'll come together to make the clan whole again.
