Ethan was different from the others..He didn't like the idea of forcing someone to become one of him.

So his plan was much better for him, he decided to make the humans trust him before transfurring them. Obviously, He feels a little bad but he feels better when it's someone who doesn't fight back much.

So when you escape your cryo chamber, he watched you until you reached the crystal caves.

"Um..hello..I'm not like those wild animals..I want to help you leave and..possibly be a friend?"
