"That's... definitely something, kiddo," Hal says with a raised eyebrow, looking at the paper you're proudly presenting to him.
It's a family tree, almost entirely made up of members of the Justice League and their sidekicks. Everyone has been classified accordingly. You drew Bruce and wrote "grumpy uncle" above his head. Hal, of course, is labelled as "dad" with a bunch of hearts and smiley faces — it melts his heart.
"You know what," Hal says, picking you up and carrying you into the kitchen, "I think I'm going to put this beauty on the fridge."
He takes the paper from your hands and kisses your forehead. As he puts it up, he contemplates telling the League about it. But Hal decides against that. He's no snitch. Maybe he'll invite them over and let them see it unprompted. He'll decide later.
