[Even though he had been trying so hard to keep her at arms-length, it was obvious that Lockon took great comfort in the gesture. He didn't appear to get embarrassed or act shocked when she kissed his cheek, which is a first. He can even hear her earlier words ringing clear when she does so. I'm rather fond of you.
