(It's important to note that while growing up, Undertaker {and presumably his deceased father} lived the vast majority of his life {entirety of the father's life} under the belief that Kane was fully related to him and his family; that is, until Bearer unintentionally {kayfabe} revealed to a Raw audience that he was actually Kane's father, this as a result of an affair Bearer had with their mother and thus making Kane and Undertaker half-brothers).
