That depends, right? I don't know what kind of compliment would be treasure for you.

[Geir's not giving her a hard time or danger flirting-- it's a genuine answer. something in his expression is soft and thoughtful, some subtle flexion of the skin around his eyes; he's thinking of who he's complimented, or thought well of, since he met Vern.

there are a lot of people he's liked a great deal since then. he can see why people would think of dragons as chary of praise, if they share his reputation, but he can at least nail down who "Geir" is enough to understand that he's genuinely not like that, not just playing a part. it gives him a a warm reassuring feeling.]

I wouldn't say it's rare, though. So you'll have to figure out what it's worth another way.
