What Castle had probably intended to be a rather innocent kiss was anything but to his wife. Kate went into it with guns blazing, sliding her hands up to cup his cheeks and attacking his mouth like the person that she was - a wife that hadn't seen her husband for three months and been carrying a load of guilt the entire time.
Could he taste her tears? She didn't know, but they were falling freely down her cheeks as Kate pulled back from the kiss, simply holding his face in her hands and soaking him in. "You're really here," she said after a moment, hastily reaching up to brush at the tear tracks on her cheeks. "I'm so happy to see you."
