The Q
Hoop’s Villain, Reality’s Hero
Still. If someone stole the source of your power you would care. He never even mentioned it. So that is either lazy writing, or he didn't know that that was the source, or he has another source of his power.
If he doesn't it's clearly no where near him cause he lost power. But the fact that he moved it around with him, would mean it's poor writing to just have a 2nd one lying around.
