I split it into two parts because I wanted the drama of it all. I hope you enjoy this.  MaximoMolasses am I still predictable? (Answer: Yes)

The team was standing in the field, unsure of where to start looking for Slade when the ground began to rumble. They began to look around for the source when the ground broke apart beneath them, causing them to fall through the hole. They landed in a plie at the bottom, on what felt like metal flooring.

Ugh, what just happened?

I think we found Slade.

More like Slade found us.

They pulled themselves together, standing up to dust themselves off. They looked around, finding a computer system on the far wall with someone sitting there with their back turned to them, feet propped up on the console.

"Slade." Dick snarled, watching as the man swirled around in his seat. He was dressed fully in uniform, his mask covering his face, but the team could sense the sneer on his face. Dick took his appearance in. "You're smaller than I pictured."

"Wait, you're saying you've never seen him in person before?" Tim asked. "How did you communicate?"

"Over the phone, wire transfers for money, you know, how you usually hire a merc." Dick shrugged. He turned his attention back to Slade. "Where is Jason?"

Slade chuckled. "Didn't you get my note? I killed the brat." Slade drew his swords. "And now I'm going to take immense pleasure in killing all of you."

"Slade, this is between you and me, let the rest of them go." Dick demanded, pulling out his weapons.

"You hired me to kill your family, X, and now that includes your team. I always uphold my end of the deal. Now, let's get this over with, shall we?" Slade leaped at Dick, clashing with him.

M'gann, shut him down!

I'm trying! He is blocking my every move!

Slade dodged Dick's kick, tossing one of his swords at the computer. It hit the screen, causing sparks to fly. The sparks hit the ground, more specifically, a puddle the team was too distracted to notice, causing a flame to erupt around the edge of the room. M'gann and Kaldur felt weak, collapsing to the ground.

"Why are we just watching Dick fight him? Let's help." Damian snarled, drawing his katana.

Artemis lifted her bow, aiming for Slade. He saw this and chuckled. "Artemis, you're helping the al Ghuls? After they sent Jason to kill your parents, your mother?"

Dick narrowed his eyes under his mask. "How do you know Jason killed them?"

"My dear boy, I know everything about my targets. Its my job to know." Slade punched Dick in the face. "I know Damian here has never killed before, I know Tim is the best fighter out of all of you, I know Jason was the most dedicated to the Shadows, and I know why you, X, wanted your brothers out of the Shadows. Too bad they'll be too dead to be heroes."

Slade dodged the arrow Artemis sent his way, turning and kicking the archer in the head. Conner went to grab Slade but he ducked under him, slashing his stomach instead. Conner stumbled backwards. "Wh-what?"

"Kryptonite blades. Curtesy of my one time employer, should I ever need them." Slade turned to Damian, Dick, and Tim. "Ready to meet your brother in hell?"

"The only one dying today is you, Slade." Dick snarled.

"You're missing an important fact."

"And that is?"

"Heroes don't kill. What would your father think of you if you killed me, after saying you would turn over a new leave?" Slade chuckled darkly. "Then you would truly have no place in this world."

Damian went to growl something in return when he felt his comm unit crackle to life, something they used when the mind link was down. "Hello? Anyone there?"

"What is it, Kid Flash?" Tim asked, keeping his eyes on Slade.

"Batman finished the analysis on the blood on Jason's uniform. Its-"

"Jason's, we know. We're kind of in the middle of something, Kid." Damian grunted.

"That's just it! The blood, its-"

"We don't have time for this, Kid Flash. Either come help us take Slade down or stop talking." Tim ripped his unit out of his ear, glaring at Slade.

Slade gestured to the bested team with his swords. "I have taken out your team, it is only a matter of time before I take you out."

"You are outnumbered, Slade."

"I was outnumbered before, but look how that turned out. Now, let's get this over with." Slade dove at Damian, kicking his legs out from under him. Damian went down, hard. Slade lifted his head off the floor, slamming it off the ground to keep him out. He looked up to be met by a punch from Tim.

He dove out of the way from the assault, slashing at Tim and Dick's legs. He caught Tim's thigh, making the fifteen year old collapse from the pain. Dick stared at his bested allies, looking up at Slade. "Its just you and me now, Slade."

"Just like its always been, Dickie." Dick was stared at Slade, unsure of what was happening. "I know the mask scrambles my voice, but you seriously don't recognize your own twin?"

"J-Jay?" The mask slid off, revealing the smirking face of Jason. "Why?"

Jason shrugged. "You know what they say, you either die a hero-" Jason dove at Dick, driving the sword through his twin's stomach. He leaned in, whispering in his ear. "-or live long enough to see yourself become the villain."

Jason backed up, pulling the sword out of Dick. He watched his twin collapse to the ground, holding his bleeding abdomen. Jason crouched next to him, taking the mask off his twin. Dick looked up at him, hurt and betrayal in his eyes. "Where's Slade?"

Jason laughed. "I killed him. Once I woke up, I freed myself from my bonds and took him by surprise, decapitating him with his own sword. I took his clothes, sprinkled his blood on my old uniform and voila! I was all set up to lure you to my trap." Jason pat Dick's head. "Wally tried to warn you that it was Slade's blood, but you wouldn't listen, would you? Too hell bent on revenge for your 'dead' brother. Well, I hate to break it to you, but I am alive and well. Can't say the same for you and your friends though, not for much longer."

"Jason, you're really going to kill us?" Tim asked, holding his bleeding leg.

"Why, of course! Once I take out my competition to the throne, I can take what is rightfully mine." Jason walked over to Tim, patting his cheek. "Its nothing personal, just business."

"You think...you think mother is going to accept the fact that you killed her sons?"

"Of course! Who do you think tipped me off to Dick being the one to hire Deathstroke in the first place?" Dick and Tim felt feeling of dread spread through out them. "If I can pull this off, I will be the sole heir to the League. Nothing holding me back. Nothing to stop me."

"Except me." The three brothers looked up to see Wally standing there with a look of rage on his face. "Its over, Jason. The Justice League is on their way. Surrender now."

Jason just bellowed out a laugh. "As if." He turned back to Dick and Tim. "I'll be seeing you around."

With that Jason ran through the flames further into the underground base, leaving Wally torn between helping his friends and boyfriend or going after Jason. He chose to stay, putting the fire out as best he could. He knelt down next to Dick and Tim, applying pressure to their wounds.

"Don't worry, the League will be here soon. Just hold on..."
