Gabriel usually had better control over his form, keeping himself from changing while sleeping after years of practice in case of an emergency where he couldn't make his way back somewhere safe to sleep, but Casey being what they were made him relax just enough that he changed back in his sleep. It was nice just sleeping with his dragonaught that he didn't even notice the fact that he had changed.

At least until he was pulled out of his sleep by hearing Casey mention something about dragons. Brown eyes opened wide to stare at them in confusion for a moment before he pulled back and studied himself to realize that yes, he had changed back into his proper form at some point during the night.

"Surprise?" His voice was deeper with a bit of a rumble to it, but it was still close enough to his human voice to be recognizable.
