Samoan ghost

There's a story among Jadzia's people. If they end their own life, they will come face to face with the Samoan ghost Xyon Quinn. It's only supposed to be a story. She doesn't believe in it. Now that she's gotten so far out that she's about to leave the world behind, she suddenly comes face to face with him. (Xyon Quinn isn't on the list of names so I can't tag him to the story.)
