DP x DC prompt where the only reason Gotham doesn’t have its own ghost population is because blood blossoms grow throughout the city.

Danny gets dragged to Gotham by his parents for a ghost hunting convention. He feels fine at first, sticking to the hotel, but as soon as Danny goes out to explore the city at night he starts to feel exhausted and ill. He tries to turn around and go back to the hotel, realizing something is wrong, but winds up collapsing outside of the park where there’s a particularly dense flowerbed of blood blossoms. He transforms, lessening the effects somewhat, but Danny still feels remarkably ill.

Bruce sees him while driving back home from a social event. Just some strange kid trying desperately to stand up and walk-- and falling repeatedly. Getting physically sick on the pavement. The kid is coherent enough to vehemently refuse being taken to a hospital, but can’t articulate much more beyond that. Bruce doesn’t know if he’s been drugged or what, but the kid is scrawny and covered in scars-- possibly abused. Determined to do something and not let the kid waste away on the side of the street, Bruce offers to let the kid rest at the manor while they try and get in contact with his family.

The kid doesn’t even get to give him a proper answer. Bruce puts a hand on his shoulder to steady him and has to make a desperate grab to catch the kid as he faints. 

Bruce takes the kid back to the manor where they try to figure out who he is while making sure he’s comfortable and not in life-threatening danger. The kid has no ID on him and doesn’t even have a cellphone (seeing as Technus smashed his last week). The kid seems stable enough-- barring a strangely low heartbeat and remaining unconscious-- but doesn’t seem to be improving.

Unfortunately for Danny, the manor is surrounded by blood blossoms.
