I've read about Constantine being the rough and tumble protector/teacher/whatever for Danny, who's the usual adhd chaos gremlin, but I want the reverse. I want an overly eager and exciteable John continually pestering Danny to take him as his apprentice in magic.
Danny probably stopped by a pub in Liverpool, in dimension something or other, to listen to some punk band play. John's singing on stage and picks up on the death magic that hangs off this 6 foot man with tousled hair and a body that's a cross between an acrobat and a brawler.
John immediately tries hitting on him and also begging him to teach him. He tries everything. He keeps hunting him down, finding new ways to summon him until Danny can't take it anymore. So, he sets him up with an impossible task.
He has to be there when he's summoned with very specific caveats in place:
1. He can't be in the dimension when the circle is made but must be present before the verbal component is spoken.
2. He can't help in any way, not with knowledge or procuring of materials.
3. The summoning spell must be requested by someone who hates and does not use magic, but is marked as accepted by the magical world.
4. He can't know why the summoning was taking place.
5. He can't have ingested any alcohol or smoked anything that day.
6. There must be 2 aliens and a being in a state of polarity present.
7. It can't be a summoning done on behalf of John Constantine, even a little bit.
And because John was adamant (and maybe threatened a bit too much chaos and fire) even against Danny's protests (because he felt a little weird about it as John was young and Danny had existed for a while) he added that if the cookie portion of his offering contained peanut butter, Danny would go on a single date with him.
Needless to say, when Danny was summoned almost 50 years later to a Space Station, he was not expecting to see a bunch of random superheroes surrounding him. And there, standing between Superman, Martian Manhunter, and Captain Marvel, was John mother-fucking Constantine grinning ear to ear.
And the cookies were peanut butter blossoms...
Ancients damnit.
