He was really good at getting reactions out of Mab, even now. She always seemed to have some kind of something for him. Whether he expected it or not. James did not expect the lick to his neck or the fang follow up. That did something quite delicious, deep down in his stomach. If he wasn't more used to the bites by now, he might have reacted a little more strongly than momentarily closing his eyes and stifling a shiver. It wasn't just the blood he received, but the action of feeding them in return if they so asked for it.
When it was done and settled once more, he let out a sigh and reopened his eyes, focusing on Rook again, listening to the way he spoke. It didn't really give him any other clues to the rest of what had happened. Normally, he could have grabbed up something if the Gangrel was in a strong emotion, but it seemed they were truly moving past it. He could have pouted, wanted to pout, but did his best not to. But wait -
Set on having this one? What did that mean? Without realizing it, his head tilted in a very specific way as he watched Rook's face more carefully. "Having this one?" Part of him wanted to take it back, in case his Master didn't really want to focus on that but he wanted to know. If he didn't want to say, he didn't have to say anything.
