You had recently broken up with Welt. Too abusive, too controlling. So you left him, thinking he'd let it go.

But he didnt let it go.

Somehow, it managed to slip away from your mind that Welt was a genius scientist. He had a few tricks up his sleeve, ones you didnt know about. And there you were, taking a walk on a rainy day -- not being able to shake off the feeling someone was watching you. You recall him telling you he'd always find you, it didnt matter if you couldnt see him.
