Siren's Judgment
Whenever someone died, Jason swore that he heard a song. Sometimes at the moment of death, other times during the funeral. But it was always present. He felt that it was calling him.
On one occasion, when Zatanna commented that the veil with the "dimension of the dead" was weak he heard the singing again. And he decided to follow it, perhaps on impulse.
He arrived at a cemetery, where a boy with white hair was singing softly to a grave. A small white sphere rose from the grave and the spirit of a girl formed around the sphere. She was laughing, and dancing around the boy. When the girl disappeared into thin air the boy stared his toxic green eyes at him.
"I was waiting for you Jason Todd" the boy said, not without kindness "I know you're not under my jurisdiction anymore but I'm worried, are you happy here?"
"What do you mean?" Jason muttered in confusion, he felt strangely calm but that only heightened his caution. "Who are you?"
"You can call me Danny" The halfa replied, giving up at keeping his name a secret, he knew that this particular soul was stubborn anyway "I'm the one in charge of taking the souls to the other side, but yours never wanted that, so I need to know, are you happy or no?"
"I don't know," Jason finally answered with a frown, "why do you want to know?"
"It's not important" Danny shrugged "I'll stick around until you figure it out, the veil will be weak for a couple of months anyway."
And with that said Danny stayed next to Jason, becoming visible only to him. The halfa needed to know that letting him revive was not a bad decision. And besides, he had to guide him in the path of the halfas later.
Jason just thought that the ghost of a mermaid was haunting him. He wondered if he should alert someone about that.
