At 42:30 Jon says Link could be Ace, but in Ocarina of Time, Link and Malon canonically had a child, because Twilight Princess Link is a direct descendent of them.
@terroni Head canon ain't canon. The twilight princess link is referred to as the "link of this era". As every link is the "link of this era". This doesn't have to equate to a direct blood relative descendant, but instead merely the person chosen/destined as the "link" of his era.
