Shaw having hair and his limbs doesn't mean anything. ObiWan is also not cut in half, or naked. "The good part" of Anakin notion doesn't fly with me. He's not Sybil, he's not Dr. jekyll. There aren't "parts". He's just Anakin. He's not reverting back to a former personality, he's the same guy, just continuing FORWARD without being a Sith asshole.
