[Kon had been freaked out when it initially happen but now he looks especially anxious about it. And a little self-conscious.]

Maybe it's the clone thing? I could just have some kind of eau de test tube smell he can somehow pick up on.

Could there be enough subtle differences from a non-cloned person that an animal could smell it and think it's weird?

[He looks to Tim because Tim has a nerdbrain and also because Tim has experience with cloning, what with all those attempts to clone him after he died.]

[It's a reach, though. He knows it is. There's a crawling feeling under his skin that's he's getting more and more aware of as time goes on, and he can't help but wonder if the dragon's smelling something to do with that.]
