A/N: GUYS! I'm back! Sorry about that, I've been having the worst writers blocks and I've been so busy with exams in school. I'll try to update more often I have a lot of ideas now about what will happen next. I hope you guys will still read, despite me not updating like every week or something. Remember, I love reading reviews, so tell me what you think! Oh and if any of you could recommend any good fanfics that would be great. Thanks guys hope you like the chap. :)

"Thanks." Matthew said, getting his drink. Before the teens could walk away, the doors of the banquet hall slammed open. "The party has arrived!" A voice said. Mika dropped her glass. Joker, Poison Ivy and Riddler stood at the entrance way, all having wicked grins plastered across their faces. "What? Surprised to see us?" Riddler asked, walking around a few children. Aaliyah blinked. "Look at this! So many rich people all in one room." Poison Ivy walked around pointing at everyone.

Bruce looked at Dick who looked ready to fight. "Dick, go get Tim and Aaliyah and get them out of here. We both know those guys are here to take her." Dick nodded and walked over to Tim and Aaliyah. Bruce nodded towards Clark who was also with Wally and Artemis. "Both of you go with Bruce. Joker is going to look for one of us. I'll distract them. Wally, when you get back, help me get these people as far away from here as possible. This is Bruce's fight." Clark said to the two young adults. With that, Wally and Artemis snuck away. Meanwhile, Dick finally managed to find both his younger siblings. "Aaliyah, we need to go. Now." Dick said. She looked hesitant for a minute, but agreed. The three of them snuck out the back of the room. Looking back, Aaliyah saw Matthew leave the room. A fight was about to happen.

Inside the hall…

"Now… this is a Wayne banquet. Where are they?" Joker asked, taking a man's wallet. Clark walked forward. "They're not here. Left a few minutes ago." Joker turned around and showed a sick smile. "Well, they better get back soon. Or I'll blow the place up! What joy right?" Clark narrowed his eyes. His fists clenched, but he couldn't blow his cover.

"What? Don't you think it's fun?" Joker said, walking around him. "Or maybe your super hero friends might come and visit. Ivy, imagine how fun that would be?" Poison Ivy laughed which echoed through the hall.

Outside the hall…

"I'll get the car." Dick said. Aaliyah grabbed his arm.

"We can't just leave. Don't you remember what happened last time my team went against these guys?" She said, a look of concern on her face.

"Aaliyah, Bruce and Clark are inside. It'll be okay. They're here to take you. We need to get you out of here." Tim said. Aaliyah looked at both of her brothers in shock.

"Are you two serious right now? You never know what could happen! Come on! We need to help! Please!" She pleaded. She turned to Tim.

"We all know Bruce. He's going to make Clark and probably Wally get people to safety. Something's not right you guys." She paused, looking down. "Guys… I can't lose anyone of them. Especially if I know they were trying to save me…" Dick sighed and paused for a minute. He face palmed. Tim knew what he was going to say. I mean, the minute the sister of the Robins started being sad, the boys would say yes to anything. "Fine. But we only stay as back up. We only go in when we are needed. Okay?" Dick said. A bright smile grew on Aaliyah's face and she enveloped both the boys in a tight hug. Before they could hug back and recover from the shock of actually getting a hug from their sister, Aaliyah ran off to the car.

Tim and Dick both looked confused, staring at their younger sister. "Do you think she's acting weird?" Dick asked.

"Uh if you think she's being way to emotional for herself and moody then yes. Yes she is." Tim replied, looking at Dick. "Probably had drunken some things." Dick tilt his head back and ran his hands through his hair. "So there's a possibility that our sister could be on the verge of getting drunk and you didn't stop me from agreeing to going against Joker, Riddler and Poison Ivy… Are you serious?!" Dick yelled. Tim laughed sheepishly. "Hehe uh now that you say it that way… uh Aaliyah!" Tim yelled, running the direction of his sister. Dick ran after the both of them. "I'm so screwed…" He muttered to himself.

Inside the hall…

Just as Joker was about to speak, Batman barged into the hall with Artemis and Kid Flash. "Joker, Riddler, Ivy. It's us you want to see." Kid Flash said.

Riddler turned around to address the trio. "Oh look who we have here. Didn't bring the newbies Batman? Or how about the other Bats? Pretty odd to see you with these two and not your Bats or even the Supers." He asked. Right there, Dash, Echo, Gray Ghost, Kage and Relic ran into the room from different directions. "First of all, we're not newbies." Kage yelled. She stood right in front of Ivy. Joker counted the teenagers. "Hmmm only 5. Where's the other one? The Bat of the team, where is she?"

"She's not here and she's not going to be." Matthew said, narrowing his eyes at Joker. The whole team knew why they were here. "Oh such a shame! She would have loved it, don't you think Batman?" Joker laughed.

"You're not going to get her." Batman said. "Over my dead body." As they were talking, Kid Flash was taking people out of the banquet hall along with Superman. "Well, I guess we'll just have to kill you then." Joker laughed. Just as that happened, Poison Ivy raised her hands, making vines crash through the windows. One of them wrapped around Kage, who tried to get herself free. Just as Ivy was about to strangle her, Dash ran and punched Ivy in the face, making her stagger. "Gray Ghost, get Kage out!" Matthew yelled. "Relic, Echo, go get Riddler!" He yelled.

"Got it." Relic said. Relic shot an arrow straight at Riddler which he managed to dodge. "Hmm not as good as some of the other archers huh?" Riddler taunted. Echo was about to use his powers, but as he opened his mouth, he fell to the floor gripping his head. "Gah!" He yelled. Relic shot another arrow at Riddler, which this time, hit him. Smoke filled the air around him, making him cough and gag. "Echo! What's going on dude?" Relic asked, running to Owen.

"It-it hurts. Something is in my head. St-stop it. Can't-can't get u-up." Echo managed to get out. Relic thought to himself. Delta wasn't here. There's only one other person who would do this. Owen started sweating, the pain clearly showing on his face.

Meanwhile, Batman and Artemis were facing off against Joker. "Artemis now!" Batman yelled, letting go of the hold he had on Joker. Artemis fired an arrow, but Joker dodged. She growled, mad that she missed. "You know, Bats, you're kind of off your game today. Something bothering you in your… head?" Suddenly, Artemis dropped to the ground as well, grabbing her head. Her eyes widened. "Artemis! Kid Flash, ask her what's going on!" Batman yelled, punching Joker. Wally sped to Artemis' side.

"What-Artemis, come on, what's happening to you?" He asked, shaking her.

"Psi-Psimon… he's here." She whispered. Kid Flash's eyes grew wide.

"Bat! It's Psimon! He's here somewhere!" he yelled. Batman showed a slight sign of concern, but dismissed it. The teenagers haven't been trained to handle Psimon. The person that wiped the team's memory before. "Echo's down too." Relic yelled, firing arrows at Riddler, covering Echo.

Outside the hall…

"They need our help." Tim said, looking through the window.

"What's going on?" Dick asked.

"They're dropping like birds. Psimon's here." Tim said.

"No. Aaliyah." Dick said, dropping down to his sister from the ledge he was on. He still hadn't recovered fully from what Psimon had done to them before and he admitted to himself that he was slightly scared of what might happen. I mean, Tim probably had a few drinks, he hadn't known how much and Aaliyah had, but based on how she was acting, something was wrong. He looked at her with concern. "They're here for me aren't they…" Aaliyah said, looking down. "Yes and Psimon is with them. Aaliyah, we're going in, but you need to make sure you don't use your powers okay? Don't use them." Dick said, grabbing her shoulders. Aaliyah didn't respond.

"Aaliyah!" Tim yelled. She snapped up and shook her head.

"Sorry, it just went foggy for a bit. I'm okay. Come on. Let's go." Aaliyah said. As Dick and Tim ran in, Aaliyah turned around as she heard a voice. Psimon stood right in front of her. She was alone.

"My, my, nice to meet you. The infamous Delta. I've heard of what you can do. Quite remarkable. I tried to get into your head earlier. I have to say, pretty hard." Psimon said, pacing around her. "What do you want?" Delta snarled. She felt sleepy. It was odd.

"You know Delta, if you were to go with me we could achieve remarkable things together." Brain said.

"You wish. I know why you all are here. You want me to go with you guys. Yeah. Not happening." Delta said. She shook her head. The sleepiness was getting worse.

"Something wrong? Had something to drink?" Brain asked, smiling. Delta backed into the banquet hall remembering the drink James had given her.

She turned around to see Joker, Ivy and Riddler tied up, surrounded by Dash, Nightwing, Robin and Batman. Everyone else was knocked out on the floor as Superman tried to wake them up. "Oh look who decided to join the fun! Hi deary!" Ivy yelled. Batman turned around. "Delta! What are you doing here! You can't be here." He told her, glaring at Dick and Tim.

"I-uh I…" Everything started going foggy. There was a sharp pain in the back of her head and she heard Psimon's voice. "Too late… I got in… Guess a bat doesn't always have their guard up." Brain said. Suddenly, Superman dropped to the floor. It looked like he was just hit with Kryptonite. "Superman!" Batman yelled.

"No…" Delta muttered, facing Batman. He looked concerned, the only emotion seen on the Bat's face tonight. "Del, what's wrong?" Dash asked, walking to her.

As the heroes were distracted, Joker, Ivy and Riddler managed to get out of the ropes.

"Too late boys, you're too late." Riddler muttered. Joker and Riddler both took out knives and before the heroes could react, they stabbed Dash and Tim in the back. Batman turned around as Joker released a gas. "No!" He yelled. It was too late.

"Gah!" He heard Nightwing yell. A knife had landed near him. A scream was heard.

"Delta!" Nightwing yelled. Just as the smoke cleared, Batman stood up. He looked around. She was gone. Delta was gone. "No!" He yelled. He tried running after her, but Dick grabbed his arm. "Batman…"

"Nightwing let go of me. I need to go after her. I nee-"

"Dad." Nightwing cut Batman off. Batman turned around to see the look on Dick's face. It was a mix of guilt, anger and sadness.

"We can't go after them now. It's no use. Look around. We need to get all of them back. Tim and Matt just got stabbed." Dick said, holding up Tim who was trying to cover up the bleeding. Batman's face softened. Superman sat up and saw the sight in front of him.

"Bat?" He asked. "Where is she?" Superman asked. Batman looked up.

"They took her. Stabbed these two as well. Believe me, I'm going to find her and they will pay." Batman said, lifting up Dash and Robin.

"We'll help you." Superman said. Batman nodded.

"We need to get these teens back to the Mountain." Batman said, walking out the door with two of them.

The next night… Nightwing's Dream…

Nightwing looked around to see himself in a cold warehouse. It was dark and eerily quiet. Something was up. Suddenly a shrill scream echoed through the building. He ran into the room it came from and saw his only sister, her costume almost unrecognizable from all the blood. "Aaliyah!" He yelled, running over to her. He knelt by her side, trying to make her look up. Finally, she did. What he saw made his step back a bit. She had a black eye and cuts all over her face. When she reached up, Nightwing grabbed her arm. Across her forearm were the words 'Joke's on you.' Seeing his sister like this made him go into a slight state of panic. He looked up into her eyes and instantly regretted it. Her pupils glowed bright red and there were tears rimming them. It's the same colour her eyes go when she uses her powers. "Aaliyah, Aaliyah I'm here. Don't cry." He said, trying to hug her. She jumped back and shook her head. "Now you come looking for me. It's too late. I've lost control." The look on her face changed from upmost sadness to coldness. Although, her eyes still showed a bit of hurt.

Dick stood up and walked towards her. She looked at him in the eyes. "You did this to me Dick." She said, her voice changing. Her voice sent chills down his spine.

"Aaliyah, I-I'm sorry." He said, trying to reach out. Aaliyah continued.

"Why did you let me fight? You knew something was wrong Dick. You knew and you still let me go. Look what happened." She said, raising her arm. Dick had to look away. He blamed himself. "You even held Bruce back from looking for me. Do you know what they did to me?!" She yelled.

"I'm sorry. I should have done more. I'm here now. Please, I want my sister back." Dick said, taking deep breaths in. Aaliyah shook her head in pain.

"It's too late now. The sister you had is gone and it's all your fault." The last sentence hurt Dick the most. It was his fault. He should have followed Bruce's orders. "Dick, why didn't you come after me? I don't want to be like this, but I don't have control anymore." Suddenly the door slammed open. A look of fear was seen in Aaliyah's red eyes.

"He's here. Go. NOW!" She yelled, pushing Dick. Joker walked in holding a crow bar.

"Hello dear, missed me?" He laughed. Dick ran out, once again leaving his sister. The last thing he heard was a scream that could break any one of the Bats.

4 am in the mountain that morning…

Nightwing woke up, sweating and head on the computer at the Mountain. Batman stood above him. "What was it?" Batman asked, knowing it was another nightmare. He had arrived at the Mountain about half an hour ago, also not being able to sleep. "Aaliyah-she was screaming. I didn't do anything about it. Bruce, It's my fault. I should have been more firm. I should have made her go home. We need to find her!" Dick said, the fear still lingering in him. He remembered every detail of the dream. Since they got to the Mountain the night before, he had been blaming himself. If he had taken them home, Delta would still be here and Tim would not have gotten stabbed. Batman sat down. "Don't worry. We will find her. I should have known she would make you stay. Dick, it's not your fault." Batman said, taking his cowl off to comfort his son. He placed his arm around Dick and felt him shaking. "Bruce, I-I can't lose another person I love. Especially at the hands of Joker…" Dick whispered. Bruce took a deep breath in remembering Jason's death. Aaliyah had been too young to remember the death, but Dick was heart broken. "It's alright, we'll find her and whatever happens, we'll get her back." Bruce said, comforting Dick. He also had been up for the past nights, trying to find his daughter. He just couldn't show his emotions to anyone except the Bats. He was Batman after all. He blamed himself for it all. He should have been the one to protect the female Bat.

"What have you been doing here?" Bruce said. "You need to get some sleep." Bruce looked at the computer screens in front of him. "I uh remember that knife that laded near me? They stabbed her Bruce. It's her blood on the knife." Dick said, composing himself and grabbing a knife in the plastic bag. "It landed near me. She was acting weird Bruce. Like really weird. Tim and I thought she just had too much to drink, but I'm not sure. I brought the knife back and I'm just-" Beep Beep Beep. He was interrupted by his computer beeping. Dick looked at the screen and clenched his fists, blocking Bruce's view of the screen. "Dick what is it?" Bruce said, expecting the worse.

"Bruce, there's traces of Ketamine in her blood. A lot of it… Someone drugged her at the party." Dick said, a sense of anger rushing through him. Bruce abruptly stood up. Anyone would cower at the glare the Bat was giving with his cowl on. No one messed with his family. Before he could say anything, Matthew burst into the room.

"Nightwing- Oh uh I'm sorry, am I interrupting something?" Matthew said, reacting to Batman's glare.

"Matt, why are you up so early? And also, how's the stab wound?" Matthew walked forward, still wincing a bit. "It's alright. Flash family speed healing right? I couldn't sleep. I was gonna check if you were awake, but I see Batman's here too." Batman hadn't looked away from the computer, which confused Matthew.

"Is everything alright? Did you find her?" He asked, slightly getting his hoped up. He himself also blamed himself for Delta's kidnapping. He had been there and he has super speed. He just let his guard down. "No." Batman said. At this time, Matthew had already read what was on the screen. "Wait, her blood contained Ketamine? Like-" He asked.

"Yes. The date-rape drug." Batman said in a monotone voice. Matthew was shocked.

"Nightwing, I thought she was on a mission with you? How could she get Ketamine in her? Speaking of which, how could you guys have gotten at the banquet so quickly, no one called for back up." Matthew looked up shocked. "Were you at the party?" He asked Nightwing. Nightwing or Bruce didn't reply. They both knew Matthew was a smart boy and having spent years with Delta, he had learnt a few things. They also knew he had his suspicions on who they were. "Nightwing, Batman, was she at the banquet?" He asked.

At this point, he knew they were hiding something and Matt was getting frustrated. He remembered everyone he talked to. Suddenly, he remembered talking to Aaliyah Wayne. Of course. How could he not have known. James had given her a drink. He saw James mix something in earlier, but didn't want to get into their business. If that was the drug… it explains why she looked so familiar and how Nightwing, Robin and Delta had gotten there within minutes without a call. Plus, both the Bats and the Waynes lived in Gotham and had the same number of people in their family. Both families were known for smarts and money. It explained why Nightwing and Delta never went with the team when the Waynes were involved. Same hair colour, voices, how could he have been so dumb?! He looked up stunned. Back and forth. He looked at Nightwing and Batman repeatedly. Batman finally looked at Matthew knowing that the boy had just found out who they were. He was going to get an explanation out of him later. Matthew finally broke the silence. "Batman, Nightwing, please tell the truth. Is Delta Aaliyah Wayne? Are the Bats the Waynes?" Matthew asked seriously. Slowly, Nightwing looked at Batman who gave him the approval look. He trusted the boy who has been dating his daughter enough. "Yes Matthew, yes we are." Nightwing said, grabbing Matt's shoulder.
