John Constantine vs Vril Dox

Two of DC's most manipulative bastards face off.

Let's make this a scenario. John Constantine joins up with L.E.G.I.O.N.. Does he become under Dox's thumb, the same as Lobo and everyone else? Does he become a thorn in his side, that Dox tolerates for his usefulness? Or does he get outplayed at his own game of subtle manipulation?

What happens?

I SOOOO dont know which way to go.
But now that you've seeded the thought this is a story I so want to see play out
