The one in which they try to make us interested in Richard’s secret biological family.
It’s a trope well-known to fantasy fiction: that the protagonist will have some sort of secret lineage that elevates him to a position of “specialness”, often compounded by a mystical prophecy surrounding the circumstances of his birth and detailing the great stuff he’s destined to do as an adult. Honestly, the number of fantasy heroes that don’t have this as an intrinsic part of their backstory are far outnumbered by the ones that do. From Luke Skywalker to Harry Potter, King Arthur to any one of the Greek heroes that were secretly sired by Zeus – a significant parentage and a great destiny go hand in hand.

And with that comes a tried-and-true method of trying to circumvent the above hero from rising: what TV Tropes calls Nice Job Breaking It Herod. The bad guy knows that a destined hero who poses a threat to his monopoly on power has been born somewhere in the vicinity, and so sends out his troops to make sure he never reaches manhood – and just to make sure the job is done properly, usually decrees that there’s no real need for accuracy. If there’s a baby, kill it.
It’s a pretty popular story in the Bible, from Moses escaping the Pharaoh’s genocide of the slave children, to King Herod sending his men out to kill Baby Jesus, but it pops up across various times and cultures: Saturn devours his own children to prevent one of them from overthrowing him, Krishna narrowly avoids the same fate at the hands of his uncle Kamsa, and Greek mythology is veritably full of baby princes who are saved by helpful shepherds who find them left to die of exposure on various hilltops because they’ll one day overthrow their fathers.
Harry Potter was targeted by Voldemort because a prophecy stated he would be his enemy’s downfall, and Jon Snow had to grow up as a disgraced bastard because his true lineage made him too vulnerable to assassination attempts. In a rare case of a heroic character greenlighting this procedure, King Arthur once ordered the drowning of babies born on May Day in an attempt to avoid the destruction that Mordred would one day unleash on Camelot, and in an even rarer female example, Willow depicted Elora Danan being hunted down as a baby after she’s foretold as being the one who will defeat the evil Queen Bavmorda (that movie ended on a weird subversion of this trope, since she didn’t have any sort of direct hand in the destruction of Bavmorda. So… was she a normal baby the whole time, and it was just the efforts of good people to protect an innocent that was the true saviour? Unclear).
You could even make a case for The Terminator movies being based on this, though the titular Terminator goes back a step in time and targets the Chosen One’s mother.
My point in bringing all this up is that Legend of the Seeker also goes to the same well in drawing up a backstory for Richard Cypher – but for some reason, whether it’s because the trope is as old as time, or because the show adds no interesting wrinkles to the familiar setup – it’s as uninteresting as it is unnecessary. Like, seriously unnecessary. I’m not sure what they do with the remaining mystery of Richard’s father in season two, but by the end of this season the revelations of his paternity and family tree which are presumably meant to rock his world, have absolutely no bearing on his character or the resolution of the plot.
It’s really quite bizarre.
