Don't own nothin'.

So, my first reaction to Robin's line in the Pilot episode of Young Justice "Pass! Batcave's crowded enough." was "Oh honey, you ain't seen nothin' yet."
I mean, if you count Alfred (which you should) there are three of them. Barbara hasn't even started as Batgirl yet, let alone are the other Batkids there.
My second reaction was "but what if they were?"
Because the saying may be "three's a crowd" but I don't really think that a kid who grew up in a circus would think so.
Enter the Batbrats. (And because this is an AU, Babs is there.)
***

Dick Grayson – 13 – Bruce Wayne's ward. Robin
Cassandra Cain - 10 - Bruce Wayne's adopted daughter. Black Bat
Jason Todd – 9/10 – Bruce Wayne's adopted son
Damian Wayne – 4 – Bruce Wayne's biological son
Timothy Drake – 8 – The kid next door (who pretty much lives at the manor because his parents are never home)
Stephanie Brown – 8/9 – A Wayne Foundation kid (Like Artemis, gets scholarships and funding from the Wayne Foundation)
Barbara Gordon – 15 – The commissioner's daughter. Batgirl

As he stepped out of the zeta into the cave, Dick looked around at the multitude of eyes boring holes in his head and winced. The Batcave was more than crowded enough.

"So…" Jason sidled up next to him, ignoring Bruce's disapproving presence. "I hear you, Kid Idiot and Fishboy went rogue." He grinned. "And you didn't take me?"

"How do you even know about that?" Dick gaped at his little brother. "I don't think there have even been any reports filed yet!"

"Babs hacked the Justice League communications." Steph chirped from where she was perched next to Cass on the hood of the Batmobile, a plate of cookies and a grumpy preschooler in between them.

Dick shot a glare at his red-headed school-mate, who simply shrugged, looking quite comfortable seated in front of the Bat-computer, her cowl down and green eyes amused. "It wasn't just me. Tim hacked the traffic and security cameras around CADMUS. We got to see your grand finale." She gave him a stern look. "Which is why I know that you are going to let Alfred look at your ribs. Wally may be fine in a couple of hours, but you don't have accelerated healing, Boy Wonder."

"Where is Tim?" Dick asked as he resignedly hopped onto the medical table and stripped off his tunic as Alfred began poking and prodding at him.

"He had to go home." Steph volunteered through her mouthful of cookie. "His new housekeeper actually pays attention sometimes, so he can't stay over too late too often."

"And you?" Dick shot back, cutting off short with a clench of his teeth as Alfred found a particularly sore spot.

"Sleepover." Cass supplied, lifting Damian down from the hood and landing lightly beside him. "Mrs. Brown said we could."

"I however," Barbara said cheerfully, getting to her feet. "Need to get home. My Dad's shift should be ending soon and if I'm not in bed when he gets back I will have a lot of explaining to do." She hugged the girls and ruffled Damian's hair, ignoring the death glare he gave her for it. "See you later kiddos! Batman, Alfred."

She disappeared from Dick's line of sight behind the cases that were currently all empty except for Cass' Black Bat uniform, and a few seconds later he heard her motorcycle start up. He was distracted by Alfred beginning to clean his cuts and by the time he could really focus on anything again Babs was gone and Damian was standing in front of him, glaring up at him fiercely.

Dick knew he was grinning like an idiot and didn't particularly care. "Hey Dami!"

If possible, the miniature scowl grew darker, the effect somewhat marred by the generous amounts of baby fat Damian had. "Gwayson." He growled.

Dick's smile grew bigger. "Yes, Little D?"

Damian just scowled harder before marching up to him stiffly, giving the harshest, shortest hug of all time to Dick's ankle (It was all he could reach) before turning and marching off again towards the stairs. The entire family watched him with varying levels of amusement, Cass and Steph following him towards the upstairs, waving goodnight to Dick as they went.

Jason hopped up on the opposite bed, sitting cross-legged and giving Dick a very focused stare. "So. A clone of Superman? Any idea how that happened?"

Dick shrugged, then winced at the pain the movement caused. "Nope. Nothing. I didn't have enough time to get into their systems."

"You okay?" The casual way Jason asked almost hid the worry in his eyes. "You did get a giant building dropped on top of you."

Dick shrugged again, knowing from the left-over twinge in his ankle that he must have wrenched it earlier, no way had Damian's hug-thing caused that all by itself. "Yeah, I'll be pretty sore for awhile though. I just don't want anymore super-powered heavy people standing on my chest again anytime soon."

A grin that made Dick a little nervous. "You have a total fanboy freakout over mini-Supes like you did with the big one?"

Bruce was suddenly there, looming, still dressed as Batman, though the cowl wasn't up. "Jason. Go upstairs. It's past your bedtime." Jason pouted, but slipped onto the floor, tossing a sympathetic (and slightly gleeful) look at Dick over his shoulder as he bounded up the stairs.

Alfred switched to inspecting his ankle and Dick wished he were a million miles away as Bruce turned to him.

He was going to be grounded for the rest of his life.
