But now that the kiss has said, now that she's back with him, he has to tell her, "I don't think you're going to die. In fact, I have every intention of making sure that you stay alive, Caroline." It's said in a low murmur that her ears should easily pick up, his tone the very continuation of that kiss as he looks at her, looks at her like he sees her, brushing hair back from her face, fingertips tracing her jaw, all manners of small touches as his other hand covers hers on his chest. "You're not going to die. I'm going to make sure of it."
