Lysander is Lex Luthor's son. He's an original character, yes, but he's also the son of a canon character.
Ok... I do not believe that the knife stood up straight from the ground so that Lysander impaled himself on it.

Despite the fact that it flew through the air end over end.... Sorry guys, but that is a plot hole so big even Big Foot could walk through it.
Like KenJ says, it's quite possible for a knife to land like that under the right circumstances. I was taking some cuttings of plants to share at work one day when I dropped the knife I was using. It landed straight up in the tangle of roots and weeds where I dropped it.
