I get to the Justice Cave two hours late and find Superboy in the front room, reading a magazine. "Hey, Robin. How you doing?"

"Hey." I look around. No sign of Impulse. Maybe I'm not the last to arrive after—

There's a crackly blur, and Bart's standing in front of Superboy, holding a wooden board. "Plank!"

"Cooler," says Superboy.

"All right! Hi, Robin! Bye, Robin!"

All I see is a blur heading out. I turn back to Superboy. "What's the story?"

"You're late," he says.

"Yeah, well—"

"I'm not busting you, man. We're all human, sorta. You hadda help Batman find the evil Jaguar Gang or whatever."

"Uh, yeah." English paper, same thing.

"All I'm saying is Imp and I had to find something to do."

Another blur, and Bart's back, holding a scrawny evergreen with dirt clods hanging off its roots. "Pine!"

"Mmm. Warmer!"

"Aww."

And Bart's gone.

"So," Superboy continues, "we started playing 'Guess What I'm Thinking.' I'm thinking of something that begins with P."

"Of course."

"You want to get in on the game?"

"Maybe next round."

Another blur. "Protractor!"

"Cooler."

"Yeah!"

I lunge for Bart, but he's already gone. I turn back to Superboy.

"Pineapple," he whispers. "You're on my team."

"Yeah. Does Bart know the rules?"

Superboy's eyebrows fly up. "They're not that complicated, Boy Genius."

"I'm just saying, it doesn't look like he—"

"Propeller!"

"Even cooler."

"Whoo! Hey!"

This time I grabbed Bart's elbow as soon as he stopped moving for a second.

"What's up, Robin? You want to play along with me?"

"Maybe next round," I repeat. "Bart, you know that 'cooler' means you're guessing worse, right?"

"Shyeah!" he scoffs. "'Cool' is good, Robbie—everyone knows that! 'Cool' is special, 'cool' is awesome, 'cool' is…cool."

"No, in this game, 'warmer' means better. Right, Superboy?"

Superboy spreads his arms in disbelief. "Of course."

"What?" Bart drops the propeller—CLANG! "Grife, man, don't you even know what 'cool' is?"

"You're telling me I don't understand 'cool'? Look, Imp, I invent new forms of 'cool' before breakfast."

"Yeah, and then you call them 'warmer'! How is anyone supposed to understand that?"

Now they're yelling over each other. This argument looks good for at least twenty minutes of Young Justice time.

We have got to get some new members.
