Warnings: a couple curse words

Shout out to Keepmovingforward2-Dick is three minutes older than Serafina.

"Come on Serafina, I know you can do this!"

Said redhead gritted her teeth and did another flip, her palms sweaty as she gripped the still rings. Her arms quivered under her weight as she held herself in a perfectly straight position in the air. Her brother was standing on a mat ten feet below her, watching her flip and twist on the rings with only the straps to hold her there. He glanced at the worn black material, trembling under her weight. Normally he didn't worry about the rings when he was on them. But with his little sister up there… he made a mental note to talk to Bruce about replacing the straps when he got back from his meeting at the Watchtower.

She strained to keep her arms straight out to the side, eyes focused on the ground below her. A bead of sweat slid down her face and found its way along her neck, tracing a slow but steady path down to her shoulders and slipping to her fingertips. She twisted so she was upside down, her body straight as a stick while she gasped for oxygen, the cool air of the Batcave filling her lungs. Dick noticed her fatigue. "Dismount. Now."

She nodded and did a couple twists to gain momentum before releasing the rings and flipping in the air. She tried the stick the landing but her tired legs refused to take all her weight at once and she fell to her knees. Heaving deep, shuddering breaths she gratefully accepted the towel offered to her by her twin. "Thanks."

He grinned at her. "No prob, sis."

She wiped her face of her sweat and stood, her legs wobbling slightly. Dick glanced at her with concern. "You might want to take a break. You've been on the rings a solid three hours, and that's longer than I've ever been able to go at once."

The younger teen nodded and slowly made her way toward a bench, watching her brother chalk his hands and step towards the uneven bars. He glanced back at her. "Spot me?"

She nodded and sat down, putting the towel around her neck. "Sure."

He grabbed the lower bar a hoisted himself up. He brought his legs up and hooked them on the pole, flipping and grabbing the higher pole. He went through a series of routines over thirty minutes, with the young redhead calling out occasional instructions. Suddenly the twins heard loud beating filled the cave, and Dick immediately dismounted. He sprinted to the Batcomputer with Serafina hot on his heels. His fingers tapped furiously on the keyboard. "Robbery at the West Gotham Jewelry store." He murmured under his breath. He grabbed his cape off the chair behind him and fastened it around his neck, then slicked his mask with spirit gum. He pressed it to his face and held it there for a few moments to secure it. He looked at his sister. "I'm going. Stay here, Alfred is right upstairs if you need anything."

"But-"

"It wasn't a request."

Said redhead huffed and crossed her arms over her chest. "You better come back safe or I'm gonna kick your ass."

He grinned at her. "You bet little sis." He sprinted to his cycle and revved the engine, speeding out of the cave in a could of smoke. She glared at the retreating form and made her way back toward the gym when a shiny price of metal caught her attention. She carefully picked up the sleek batarang, carefully turning it in her hands and studying it from different angles. She glanced at a target across from her and flipped it on the flat side. She gripped the edge and flicked her wrist, sending it flying toward the target. She grinned to herself when it lodged just beneath the center. She scooped up an armful of weapons.

Dick had been gone almost two hours, and Serafina was getting better. Her first shot had been a lucky one, as she had found out when she brought her arm back to throw another and accidentally released it before she could throw it. She sure hoped the giant T-Rex didn't have anything important lodged in it's stomach. Her attention was drawn away when she heard roaring engines and two bright headlights appeared. The Batmobile pulled onto the parking ramp, and Batman stepped out. The young redhead walked casually over to her father, who looked behind her as if looking for someone. "Where's Robin?"

She crossed her arms over her chest. "And hello to you too." A frown crossed her pretty features. "Wait, you mean he's not with you?"

The Dark Knight shook his head. "No. He wasn't at the normal rendezvous point. He's not here?"

Her brow knit together. "No. He went out about two hours ago and when he didn't come back I assumed he met up with you wherever you two go."

In an instant Bruce was at the computer, cowl down and fingers working at a furious pace. "Where did he go?"

The youngest Grayson racked her brain, trying to remember. "I think he said the West Gotham Jewelry store."

The billionaire nodded thoughtfully and pulled up the tracking information on Robin's GPS. A map of Gotham appeared on the screen, a red dot positioned directly over the Manor. It moved as Batman fast forwarded the time. It lingered at the street address of the jewelry store, then it was moving again. It stopped at a few other places before coming to a final halt. The teen leaned over Bruce's shoulder to get a better look at the map. "That's the old apartment complex on Raymond street."

Bruce sent a look in her general direction. "How did you…?"

A light blush painted her cheeks as she reached forward and tapped a place about a block from the building. "That's the last place I was." Bruce couldn't help but notice how she didn't refer to it as her last home. Or her last family.

However he let it pass as he stood and pulled his cowl back down. He briskly made his way back toward the Batmobile and leapt in. He was about to slide the roof back in it's position and drive off when a hand slammed down on the steering wheel. "I'm coming with you." He glanced up, and was met by a pair of boiling jaded emeralds. "I'm a civilian. I can get into places you can't."

He gave her the Batglare, but her own angry gaze leveled the field. Eventually he sighed and jerked his head toward to lockers. "Change. Two minutes."

She nodded and sprinted in the direction of the lockers. Exactly two minutes later she was running at top speed toward the sleek black car. She put a hand on the door a jumped over it, landing in the seat without a sound. "Let's go."

The roof slid silently into position, and the car rocketed forward. Serafina clung to the seat at the high speed, then relaxed. A whoop of joy escaped her lips. "This is AWESOME!"

A smile tugged at Batman's lips as she laughed. The first time Dick had ever gone that fast he had wet his tights. Now that was a mess he didn't want to clean up twice. In a few minutes they were at the street address of the apartment complex. He rolled down the window and slipped a small black disk with a red and a blue button into her hand. "Check the ground floor first, if he was kidnapped they wouldn't have taken him any farther. Bottom floor provides the quickest getaway. If it's clear, go check the alleys. The blue button lets me hear what's going on, the red one tells me to come in and get you. Got it?" She nodded and started to climb out the window, when Bruce grabbed her wrist. "Serafina. Be careful."

She gave him a million dollar smile. "Come on now, Dad. You know me."

"That's exactly why I'm worried."

A brief chuckle escaped her as she exited via window and her feet landed on the pavement. She stalked to the door and cracked it open, peering cautiously inside before gingerly opening it and stepping out of her father's safe watch and into the abandoned building. The ballerina flats that she had changed into didn't make a sound on the old floor, a small cloud of filmy dust and dirt covering the once polished wood floors. He dark clothes made her blend in like a silent shadow stealing through the darkness. Her sweep of the first floor revealed nothing interesting, so she crept to the back door and pressed her ear against it, listening for anything. She could hear muffled speaking, a man's deep voice, through the rotting wooden door. She circled back around to the front door and closed it carefully behind her.

Batman started to rise, but stopped when the redhead's hand snapped up in a stop position. He watched carefully as she spelled out a word in sign language. Wait.

The billionaire playboy sigh and sat back down, but mentally thanked himself for teaching his daughter sign language. She tip-toed around the car and pressed herself against the wall before slipping around the corner and disappearing from her father's view. Her eyes darted to a man holding up a boy in a red vest. Her breath caught in her throat. Dick. She ground her teeth so hard she heard something crack in her back teeth. 'What did this son of a bitch do the my brother?'

Her brain raced. 'Okay, now how do I get him away from Dick and how do I kick his sorry behind to Timbuktu?' Her fingers found the disk Batman gave her and traced the outline of the blue button as a plan slowly formulated in her head. The acrobat took a breath and crossed her legs in front of her, her back against the dirty building wall. Her dark blue jeans and black long sleeve top blended her in with the shadows the surrounded her. She pressed the button and crossed her arms over her chest, dropping her head so her hair veiled her face. 'Dad's gonna kill me.'

"I wouldn't do that if I were you."

The man whirled around, her brother's vest still clenched in his fist. She looked up at him, the red curtain of hair still concealing her eyes. She nodded toward the raven. "You know who he is, right?"

The man glanced down. "Yup."

"Then you know that this is equivalent to suicide."

His fist quivered by his side. "I ain't scared of no masked freak."

"You should be." The redhead pushed off the wall and sauntered toward the stranger. "You should be cowering in the corner."

"Why the 'ell should I do that?"

"This is the Bat we're talking about. Anyone who hurts his bird…" At this point she was right up on him. "Well, let's just say that Batman has anger issues." She clicked her tongue. "And that's not even thinking about the Justice League."

His eyes got wide at the mention of that. "J-Justice League?"

She smiled sweetly. "Aw, aren't you so just innocent. Capes have to stick together, you know. And you can't exactly torture one of their own without drawing attention." She walked her fingers up his chest, trying to appear flirtatious. "And you really don't want Superman as an enemy."

He snorted, but paled none the less. "How would he know?"

She laughed lightly. "Come on now, sweetie. Are you forgetting that Superman has both super hearing and x-ray vision?" She smiled up coyly. "He knows." She whispered.

She could feel his pulse skyrocket under her fingertips. His breathing quickened as he stammered in vain attempt to speak. She gently smacked his chest. "Oh calm down. Leave him, I'll help you hide."

He breathed in relieve. "Really?"

She gave him a once over and allowed a small smirk to appear on her face. "For you, sweet pea? Anything."

A relieved grin spread across his face, and she stepped aside, pointing down the alley. "My ride is just around the corner."

The gullible man dropped her twin roughly to the ground and began walking toward the mouth of the alley, but the instant his back was turned Serafina's friendly emeralds turned cold. She brought her hand down in a karate chop on a nerve point that Dick had taught her, and the man dropped unconscious. She blew her hair out of her face and began helping her brother off the alley floor. The aerialist was staring at her, awe written like a book on his face. "Did you just-?"

"Flirt with a thirty-something year old man to save your ass? Yeah, I did." The youngest Grayson looked at her brother in concern. "You all right, Dickie-bird?"

"You know, I've been thinking."

"That's always dangerous."

"Shut up. Anyway, everyone in our family has a nickname except you."

"Why are you thinking about nicknames when I'm saving your butt?"

"My mind wanders, okay. But then it hit me."

"What? The secret to life, the universe, and everything?"

"No, the perfect nickname. Bruce is DaddyBats, I'm Dickie-bird, and you, my dear sister," he paused for dramatic effect, "are Ser-bear."

She looked at him, incredulous. "Seriously?" The short boy nodded. "Dude, you've been MIA for what, two hours and that's what you come up with?"

"Yeah, pretty much." She walked with him toward the Batmobile, assuming their father was still there. The teen stepped over the unconscious man, still lying on the ground. When she saw her brother turn back, she put a hand of his shoulder. "Leave him. He'll come to eventually."

Robin nodded and followed his little sister out to the Batmobile, where his mentor was waiting. He climbed in the shotgun seat while Serafina took the backseat. "Are you alright?" Batman asked.

The ebony looked to his father. "Yeah, nothing a hot shower won't fix."

The older man nodded and started the car, driving toward the Manor. It was quiet in the car until a stifled yawn was heard from the back. Dick grinned and turn around in his chair to face the girl in the back. "Tired Ser-bear?"

"Dick."

"Yes little sister?"

"Shut up."
