You are entirely right here!for me, it would mean that sneddon and his croonies took NOTHING, absolutely NOTHING from him, not even the joy felt when entering Neverland's gates, not even the "home" that once was inside Neverland.
For me just the thought that the placed he build with so much LOVE was stripped from it's special meaning it's heartbreaking.
Michael moving back in would mean that after all was said and done, not only they could NOT break him, but they couldn't even take the joy of calling Neverland home away from him.
