"Okay, I've seen ghosts that look like dragons, lunch meat, plants, and dinosaurs but... this is definitely a new one."

Danny hovered in his dream, staring at a triangle wearing a top hat. It had a single slit pupiled eye, and a black bow tie.

"There's only one me Spook. And, I might add, only one you. Name's Bill, Bill Cipher."

"Danny Phantom," he replied coolly.

"Ha! Nice play on words Fenton. Yeah, I know who you are," he continued, ignoring his shocked face. "Everybody in the ghost zone and beyond knows who you are." 

In response to his words, the dream shifted around them. The eerie greens of the ghost zone wavered into existence. Hovering doors floated in a ring around them. 

"So kid, hows the double life treating you? Ghost hunter at night, high school outcast during the day. Boy if I were you, I'd show those jocks a thing or two about real power."

He opened a door and revealed a flashback. Dash beating him up. Paulina laughing at him. Quan shoving him inside his own locker. 

Danny bit back his anger. 

"Well you get used to it. But what's your angle anyway?" he said, turning the topic back to Bill. "You don't seem to have any power over the human world. You can't even take physical form!"

Bill's single eye narrowed. 

"No power in your world? You've gotta be joking. You think all these ghosts of yours would find their way out if someone didn't show 'em? Where do you think they learn new entrances, gain new powers? I'll give you a hint."

He opened another door. 

Bill upgrading Skullker's suit. Bill teaching Kitty how to use her ecto kiss. Bill shaking hands with Technus. 

"Just cause I'm sneaky doesn't mean I'm not strong Spook. I know things. Secrets, powers, artifacts.  All your little enemies are just pawns to me. I've been making deals. Changing minds."

Danny began to feel nervous. If Bill really was as powerful as he claimed, then he was in Bill's element. Not a great place to be. 

"So what's your play?" he asked, still trying to sound bored. 

"Oh kid. You must think I'm Technus, about to shout my plans out for the whole world to hear. No, all you get is a hint and an offer. Hint: You'll run across problems that you can't solve soon. Offer: I'm a handy guy to have on your side. I can unlock powers you didn't know you had."

The dream around them began to rotate.

"Why would you help me?" Danny asked.

"Well seeing as your buddy Vlad is only interested in the tiny human world, I figure you'll be more open to learn a thing or two. I'll give you time to think about it. But don't worry. Things are gonna be fun around town for you while you're here. Spend some time at the Mystery Shack if you're bored. There'll be some people very interested to meet you!" 

The surroundings spun faster and faster. Doors flew open and ghosts surged out, spiraling around them. 

"See you Spook!"

Danny jerked awake, sweat beading his head. Jazz sat up abruptly. 

"Danny, what's wrong? Are you okay?"

He lay back down, head still full of Bill's voice and the whirling chaos of the dream. 

"I'm fine," he said, not looking at her.

"Just a dream."
