He's been with Asher long enough to be able to read his vampire. Nathaniel knows it isn't all right. He crawls into Asher's lap, knees resting on either side of Asher's thighs, and presses his face to Asher's throat.

"Please don't be angry," he whispers. "Please don't be sad. I'm yours, Asher, yours. I promise. Your cat, yours."

Nathaniel just keeps whispering 'yours' to Asher, wanting to promise anything and everything to the master vampire.
