But, yeah. One thing to note about the Camelot kiss is that, at the time, Emma wanted to be free of the Dark One’s curse. She used light magic. Despite what Head!Rumpel said, she did not really get a taste of the darkness and liked it. The gold on her skin appeared after the kiss. When Belle kissed Rumpel, he had to shake it off. Literally. That was the only time TLK has been used on the Dark One, that we’ve seen. Basically, it appears that Hook is a rebound after Nealfire’s death. Nothing more. Still a codfish.
