Fan Casting Neron in Justice League Dark 2

Maybe the one who encouraged Klarion to move, see's the JL Dark as a threat and wants Klarion to weaken them, which maybe he does in the end and Klarion is more or less gleeful and warns that "He's coming, you think I'm a demon, (slightly does a grimace or sly smile) wait till you dance with a real devil!" Hahaha! Teleports yadda yadda you get the idea. Has been released by Klarion mid movie but not physically shown, maybe Klarion is looking towards the camera (kind of) and says something like "a deals a deal!" Or something cooler Idk, idea is that Klarion would of had his part fulfilled by Neron and would enjoy the challenge of taking on the JLD anyway
