Dick puts everything on the line. He's the last one standing. The rest of the Titans are down. He dies making sure that they, and the world, can live.

Then he wakes up, staring at a ceiling dotted with glow in the dark stars, very confused.

There's a redheaded teenager who calls herself Jazz, who seems suspicious of him. He had parents, ghost hunters who are definitely breaking many, many laws, who love him dearly.

He has a pair of very close friends, Tucker and Sam, who also do not trust him.

There was a funeral for Dick Grayson, he looked it up. There was a corpse and everything, cremated exactly as he had demanded after learning what had happened to Jason.

Just in case it's a fluke, and he's about to be thrown out of a body that isn't his, he doesn't reach out to anyone in the hero community just yet. Instead, he decides to look into who, exactly, is Daniel Fenton, and why do his friends and sister keep looking at him like he's a spy?

Or; Danny, growing more and more powerful as a halfa, was starting to have his ghostlyness leak through to his human form. He asked Clockwork if there was a future where Jack and Maddie would ever accept him being half ghost, and Clockwork informed him that no, there was not. So Danny worked with the Yetis in the Far Frozen to make a lifeless clone of himself, with the intent to fake his death and live on in the Realms. So when Jazz came into his room, fully expecting a lifeless clone, only to find the clone not only alive but fully functional, she's suspicious.
