Plot Bunny #7: John Constantine as Harry's mentor.

I recently saw a few scenes of the new DC animated movie called Justice League Dark and I rather liked the incarnation of John Constantine. He plays with fire, he's irreverent and he's a damn badass. He is clearly a unique magician/wizard or whatever name of spell caster he really is.

What I would like to see is that somehow, Harry's semi regular bouts of accidental magic catch the attention of a few contacts of Constantine and after one very large feat, someone decide that it's time to call the expert to investigate. Hence the reason why Constantine would eventually find himself at #4 Privet Drive, likely comment about the weird wards too.

You see, the magical community in the U.K is more diverse than the books. There are those who use wands and those who don't need them but need a magic circle instead. Each one had their advantages and disadvantages, likely the debate power VS versatility. From there I lack a real plot, but I'd like to see some sort of interactions between both Harry and John. Maybe the Detective of the paranormal could take him away from there. His life is not the most stable of the lot but maybe having an apprentice could be fun? And when he goes to Hogwarts, there's the whole library that could be useful for researching stuff.

I also see a brief scene where Jason Blood unleash the Demon Etrigan on Slytherin's Basilisk. XD

Well, that's all I can squeeze out of my brain. Till the next idea!
