The Undertaker, because it's a secret.
Undertaker, Kane, and Lita are NOT related. If you think they are, it's probably from a storyline that the WWE went with. I know years ago Kane and Undertaker were brothers. But in real life, none are related to each other whatsoever. So, there is no secret because it's not true.
