Are you lonely

I have been reading a lot of ghost cultures/instincts prompts and the plot bunnies in my brain are popping.

Ghosts can make a wide variety of sounds since their vocal cords are limited by essentially nothing. It's important for their growth and to destress themselves.

Jason is not really a halfta since he got dragged back up to the living before he finished forming a core and then was dipped in the Pit, which stunted the growth. He has all the instincts, but not the right body.

Luckily, Gotham has enough natural ectoplasm for his body to fix itself.

He patrols Crime Alley near obsessively and seems to somehow always know when there's a bat at his border; he chalked it up to the Pit's side effects (Ra's the only one experienced enough in this, and he's not asking that madman). There's also this hunger that, no matter how much he eats, seems never to be filled. Whistling is Jason's favorite activity to do whenever he's alone; he does it as often as he patrols (Jason doesn't know, but before he was dipped, thrills and whistling were the only languages he would use to communicate). He's not stupid enough to always do it as Red Hood, but he couldn't help how much the tune calmed him down whenever the loneliness(?) got too much.

Unknown to Jason, the little tune has been echoing for miles like a haunting whale song, audial for every ghost that is currently existing in the living world.

Danny, trying to find this isolated halfta(?): Did the GIW get him? Is that why he sounds so sad??? I needs to help this person!!!
