It’s over, isn’t it? Well technically it was over after Together Again if you consider the timeline, but Wizard City was the last to air. This is a very different Peppermint Butler from the one we knew, but we know he gets his power back in the end.
As for Wizard City? Well that’s a wild place. We don’t know why they hate Peppermint Butler so much, we just know that Cadebra is probably the most supportive friend in media right now.
