I was answering all of your questions when:

"Do you think he wouldn't notice how the island went from being normal to instantaneously half freezing and half burning?"

I...am...fucked xD (Troll) maybe he was "awake" for a while...?!

EDIT of the theory to be more accurate and to survives your questions xD : he was kidnapped at the same time as his son: and he was DIRECTLY sent to the Labs; so he didn't see the island before except the complex.

For the centaurs, the jails aren't like in impel down, that's closed rooms.

Law has just protect his secret.
