The first obvious thing about the bond is that they love her, both of them - that's not always true, with co-Bondmates, but it is true here.

The second is that there are not really three people here. There are two, in three bodies. The demon and the dragon are not at all shy about Isibel seeing into their thoughts, and in the newness of the bond that is still possible. They are one, in a way that dragon and Bonded usually aren't. Two separate experiences of the world, two separate voices, but one unified mind.

And they love her, and they are sorry.
