Tucker and Danny were playing with the Scarab Scepter, Sam told them it was a bad idea but they didn't think Duulaman would be a problem.
Well, not until Tucker joking said "Danny Phantom, you are under my control now" with a villain voice, suddenly he realized what he have done "Oh God, Danny sorry, I forgot about Freakshow incident, I was joking, I swear, please don't be mad at me"
But Danny didn't answer, Tucker open his eyes and saw his friend completely mind controlled, it does not matter how many times he yell "You are not under my control anymore" he couldn't reverse it, Duulaman's Scepter didn't reverse it.
Now he needed to figure out how to call Justice League and said "Oh sorry, I mind controlled my best friend with a magic staff that can change reality at my will but don't worry I am not a villain ¿please help me?" yeah, Sam was going to kill him sooner than later.
