"Don't forget your superpower, 'Plunderer' Budman Avis. When you killed Kova, you plundered his earth-burrowing ability!
With the experience you've accumulated over the years, you immediately realized that he was being hunted. If Kova's pursuer was a Superpower User you couldn't instantly kill, then you really couldn't cover up this bloody case! So, you immediately grabbed his body and burrowed into the ground, not looking back as you fled into the distance. That earring dropped on the ground at that moment."
