You were a human, that had fallen into the underground. Coincidentally, a skeleton in the underground needed a new test experiment, a lab rat, of some sort, and you were just what he needed.

After a few days of stalking you, he kidnapped you in a moment you were most vulnerable. Sci had taken you back to his lab, and had you strapped down to a table.

When you started to regain consciousness, he was sitting down beside you, sharpening his tools with a malicious grin on his face.
