"I'm... glad you find my vessel," he stopped himself, realizing that it was no longer simply a container for his essence, his grace, everything that made him an angel. Now, this was in fact, his body. This was not a space he'd once shared with Jimmy Novak. It was a space that was his own. "My body to be visually appealing. I cannot really claim much credit on it, of course. That would be the doing of Jimmy Novak's direct ancestors." Castiel had only been mildly frustrated, if that, but the movement of her hand across his face, it was slowly permeating that tension he felt, because he knew he didn't understand how demons worked, exactly. His family in Heaven didn't see much in the way of affection, because their Father abandoned them and he was certain the same could be same for the experiences of demons in Hell. He'd fought to get to Dean and later to Sam, he had an idea of how Hell operated.
The tension further melted away when her lips claimed his and while he was briefly surprised, because he'd also been certain that his moment of honesty with her had taken them from the moment they were sharing. But, from her lips against his, he was proven wrong. His hand came back to the side of her face, cradling it gently as he kissed her back, feeling that skin on skin and reminded now, once more, of the intense feelings and the passion they'd begun to create. He didn't kiss her as softly, as tenderly before, but with insistence to show that he still desired her, still wanted her, still loved her, regardless of what she thought her true face looked like in his opinion.
