"So," Wally continued, "force is equal to...?"

Arsenal buried his flesh hand in his hair. "Mass times acceleration. I already know all this!"

"Which is why you'll test out just fine, but the League needs to know you can. Come on, next question."

Wally looked up to see three of the bat brothers walk into the Hall. "Hey, there!" he called, waving.

Tim gave a small wave back then promptly returned to his conversation with his brothers.

"Tt," Damian said. "Grayson is a fool."

"I agree with you there, Demon Spawn," Jason grumbled. "Thinks he can be the boss of me?"

"He's working himself to death, too," Tim added. "Like that won't make him a liability in the field."

Jason snorted, rolling his eyes. "You'd think he'd have learned from last time."

"They're talking about Nightwing?" Arsenal asked, nudging Wally.

The speedster nodded.

"The short stack is right, he is pretty stupid."

"Excuse me!" Damian screeched, stomping up to the desk. "What did you just say about my brother?"

Wally let his face fall to the desk, really not needing this so early in the morning.

"Nothing you didn't say first," Roy shot back.

Jason loomed over the redhead. "Yeah, cause he's our brother, not yours, last I checked."

Arsenal snarled.

Damian snarled.

Damian attacked.

Wally sped out of the way, keeping as much distance between them as possible.

Tim watched, calculating, for a moment before joining the fray.

Suddenly, there was a laser aimed for Wally's head, and he just barely ducked out of the way, looking mournfully back at the now toasted books.

Jason cackled, pulling out his guns, making a show of cocking first one then the other.

"Oh, thank God," Wally murmured, sagging against the wall in relief.

"Jason! Damian! Tim!" Nightwing snapped. "What are you doing?"

"Defending your honor," Damian replied with a well-timed kick to Arsenal's face.

Dick's face met his palm. "I am way too tired to deal with this. Come on, let's go home. Take that 'break' you three talk so much about."

The three were immediately at their older brother's side, taking up what seemed to be a protective formation as they followed him out of the building.

"That," Wally glared at Roy, "was a whole new level of stupid."

Arsenal kicked an overturned chair. "I'm done with my homework."

"Good," Wally said.
