Whatever was said between the two wasn't in a human tongue and Raven refused to repeat what it was, but in the end the demon lost the conflict and was... absorbed.
"Oh, that ain't pretty," observed Cyborg.
Raven, however, had a different reaction. "He lost... I can't feel him anymore. I... I think I'm free."
The titanic brute shrank down after Trigon was subsumed, standing at about fourteen feet tall. Demona and Red X went to him, Red X ditching his mask, and he ruffled the kid's black hair while praising him for the good work. The other heroes went to them, as the world began to return to normal; he extinguished his flames and shrank to the size of a normal adult. He removed his helmet as well, holding it under an arm, before the trio turned toward the heroes.
"Impossible," breathed Robin, as he saw the spitting images of himself and Bruce Wayne looking back to him.
"Well, that was quite an experience! I don't think that Trigon will be able to bothering anyone again," he commented. "Huh, you look a lot like..." He paused, looking between Red X and Robin. Then shrugged. "Well, that explains some things. It's been fun, but if your world's safe, I think we should be moving on."
"What a twist!" exclaimed a pink-haired bystander, before she ran away. The heroes stared after her for a moment, before turning back to the trio, but in that brief span of time two of the three had disappeared.
Red X shrugged and commented, "I figured I'd stick around a little longer. See you around, heroes." And with the firing of a grapnel, he shot off into the skyline.
Fostering that kid for a few years and teaching him the art of trolling was as hilarious and ideal a result as one could hope.
