I’m tired of Danny being annoyed with Constantine with him constantly selling his soul. I want Danny to fucking love it. Danny is a little chaos gremlin and nothing would bring him more pleasure than fucking with demons and whatever else Constantine sold himself to. It would be the highlight of his week when doing paperwork because 50+ whatever entities come in to complain and Danny can just go “damn, sucks to be you I guess :)”
Danny fully intends on claiming this man's soul the moment he dies, just to watch the chaos ensue. He won't even care about punishing John or anything, just let's him go back to the Mortal Realm as a ghost to hang out with (annoy) his hero friends.
Deadman visits the palace to gossip with him about what Constantine's been getting up to, and Danny gives him a power boost so he can survive on the mortal realm for longer.
Now there is a door connecting deadman's "living" space to the house of mysteries and one of the private boudoir of phamtom castle for their ecto tea and gossip session on saturday
And for more chaos: Phamtom makes Constantine (on his death) one of his diplomatic ghosts (because everyone knows him and recognizes him, he's a talent with him appearance quite commonplace for kingdoms) and royal notaries (he got you all with his contracts so he's better than you, I want him by my side) giving him the diplomatic immunizer and a portal power (which he already had in another form so just a power up I guess)
just imagine the mouths of the various demons and co skimmed, yum, they can't even contradict Danny's arguments. Not because it's a particularly good argument, but because it would be insubordination. This is the first time he has recruited a soul outside of his group of liminal friends. No one wants to mess up their first real mortal soul claims (it's like a baby's first steps (for a demon))
