time sequence is a bit weird here. don't know what I was thinking. Sorry.
Earlier-
Robin returned from stealing the Thermal Blaster, depressed.
"Excellent, Robin. I'm pleased. You're already proving to be a perfect apprentice." Slade's voice pierced the darkness.
"This deal can't last forever!" Robin said defiantly.
"It can and it will." Slade pushed a button and a wall of monitors came to life, each showing a Titans blood stream, crawling with electric devices. "The Titans still have no idea that my chronoton detonator was more than a decoy. Now that my probes are inside their bodies, they could remain undetected for years, decades."
"Sooner or later, you will let your guard down. I will get that controller and the instant they are out of danger, you will pay."
"That sounds like a threat young man. Quite a good threat actually. Betrayal, destruction, revenge. We really do think alike." Slade smiled. He wasn't like Slade. Robin gritted his teeth and charged his would be mentor. He didn't even lay a hand on him as Slade grabbed his wrist and twisted his arm behind his back. The bones grind and creak worryingly. It's one of Slade's favourite moves and Robins arm already aches from his last show of mettle. "I monitored your vital signs during the mission. Elevated heart rate, adrenaline, and endorphins. You won't admit it, but at some level, you enjoyed stealing for me. It was a thrill, wasn't it?" he finally released Robin and the apprentice staggered to one side clutching his poor arm. "You're going to keep stealing for me, and you're going to keep getting that thrill. And sooner or later, you're going to see things my way." Slade took Robin's right arm gently in hand and attached the Thermal Blaster he had had the boy steal. "Who knows, I might even become like a father to you."
Robin lowered his arm sullenly and refused to meet Slade's eyes.
"I already had a father." He replied softly. A flutter of wings echoed around Slade's lair. A few bats fly from their hiding place past the pair and up into the night.
Now-
Robin looked up at the building Slade had sent him to and smiled ruefully. The irony of his situation didn't escape him. He threw his grappling hook and began to climb. He stopped two floors from the roof and smashed, feet first through a window, not worried by the alarm. He runs through the building. First left, second right, don't stop. He came to a halt in front of large reinforced steel doors with a huge 'W' on them. He attached a small device, marked with Slade's stylistic 'S' to the doors, then retreats a few paces. The door explodes. The room beyond is dimly lit, and almost completely empty, save for a little gadget suspended in a force field at the centre. He approached it cautiously, slowly. His hand extended. He was about to take it when…
"You aren't walking outta here Robin!" Cyborg's voice was loud and sure. Their ex-team-mate span in his tracks to see the remaining Titans stood in the wreck of the doorway. "Not without a fight!" Robin charged with a cry and Cyborg called out "Titans go!" The Titans raced across the floor, Beastboy turned into a tiger as he ran, and Star primed a star-bolt. Robin dodged Cyborg's punch and Beastboy's lunge. Beastboy changes back to human form and Robin vaulted over his head. He sailed neatly between Starfire and Raven and tore away a ceiling panel. He was away before his former fellows could react. The starred, flabbergasted at the opening through which he fled.
Up on the roof, Robin has emerged. He was silhouetted against the neon lights which spell the word 'Wayne' in capitals. He ran across the roof, reaching for his utility belt.
"Not so fast Robin. You have yet to achieve your objective." Slade's voice sounded in Robin's earpiece.
"The device was too heavily guarded. I'll have to steal it another-" Robin was cut off.
"NO!" Robin flinched at Slade's anger. "Go back. Unless you want me to destroy them, go back and fight." Robin stands undecided.
"Robin!" Cyborg's voice sounded from behind. He turned. "Look, I don't know what's going on, but we don't want to fight. We just want to talk." Cyborg had his hands raised as though in supplication. Robin was touched by this display of loyalty and friendship. They were risking an attack to try and help him. He could only do the same. So, with a yell, he launched a flying kick which sent Cyborg staggering.
"Guess there's nothing to talk about." Beastboy made his voice hard. He cracked his knuckles and transforms into a green gorilla.
Just then, the Bat copter landed a few roofs away. The three passengers emerged.
"It really is him." Barbara gasped as she saw the fight. "I guess I was hoping…"
"I k now what you mean." Batman agreed.
"You must help him, Master Bruce." Alfred pleaded.
"Let's see what happens first."
Beastboy banged his fists on the rooftop, narrowly missing the boy-wonder who leaped backwards again and again as Beastboy presses his attack. Robin launched up and forwards to perch in the centre of the 'A' in WAYNE. A huge green hand follows him but grasps air. Robin had jumped to the 'A's peak then back down towards the roof to as Beastboy climbs up after him. In the air, Robin twisted and pulls out a Slade-a-rang. It shoots a rope out as he throws it, and this winds itself around one of Beastboy's wrists. Robin drops down through the centre of the 'A'. He threads the rope through and it is pulled taut, yanking Beastboy through the too tight hole so that he is stuck. Robin finds himself face to face with Star.
"Please-"she said before he rushes past her to come down with a flying kick and a flurry of strikes against Raven. Cyborg aims and primes his sonic cannon. He filled with dismay and unease. His uncertainty was clear on his face.
"Don't make me…" he begged. Then, with a growl of pent up emotion, he gave up, disarmed and ran in to do this the old fashioned way. The punch he threw missed Robin and connected against the shield Raven had thrown up to protect herself from Robin.
"These kids can handle themselves." Batman said from his nearby perch.
"He's still not trying to hurt them" Oracle countered. "Did you see him avoid Starfire?"
Above the fighting across the way Beastboy has finally broken free from the 'A' by changing to a snake and slithering down. When he got back on solid roof, he turned into a Ram with large curved horns and charged. He slammed into Robin, sending him rolling to the edge. Robin stopped just in time to prevent certain death. He lies still. Beastboy, shocked at what he had done to the boy he still considered his leader.
"Dude!" he ran over, amazed he'd managed to hit him. "Are you okay?" Robin answered with a high kick to the chest, knocking him back into Cyborg.
"Fight to win Robin. Use the Thermal Blaster," Slade said in Robin's ear. Raven rose to the air in front of him.
"Azarath Metrion Zinthos!" Robin was suddenly encased from neck to knees. Somehow he managed to get his right arm free. He sent a Slade-a-rang flying towards Raven. It exploded inches from her face.
"I…I can't see!" she cried falling as her power broke.
"No!" Starfire gasped. Robin meanwhile, freed as Raven fell, had re-engaged Cyborg. He was hitting the half-man, half-machine, who backed away, blocking the punches.
"Come on, man, don't make me do this! I don't want to do this!" Cyborg pleaded. He grabbed his arm, preparing to fire his Sonic Cannon, but a low foot got under his guard, knocking him to the floor. The Sonic Blast went off as he fell and Robin leaped away. He landed back atop the 'A'. As his friends (former) started to recover and press the attack, he ran from one letter to the next. He reached the 'E'. Starfire, furious, was waiting for him at the end. She steeled herself, readying a Starbolt.
"STOP!" she commanded. He did so. "Do not move!"
"I thought I told you to use the Blaster. Attack! Now!" Slade's voice sounded in his ear. Robin readied the weapon to fire on Star, his face set in a snarl. She was torn, her eyes wide. Friend or foe? She lowered her arm and the starbolt went out. She looked down, sad, confused.
"Robin, you are my best friend. I cannot be in a world where we must fight. If you are truly evil, then go ahead. Do what you must." Her voice trembled.
On the other roof the three onlookers starred in confusion and amazement.
"What is she doing?" Barbara cried out. "Do something Bruce!"
Star just stood there, head bowed, defenceless. Robin stared at her in disbelief, eyes wide. He lowered the blaster, and took a trembling step forward (on the other roof, Batman has removed a grappling hook and rope from his belt).
"Starfire! No! I—"a shrill burst of feedback from his earpiece made Robin stop and grab his ear. "Aaarrrgh!"
"ROBIN! I gave you an order!" Slade was stunned. "If you won't attack, my probes will." And so they do, as Slade pressed the trigger with malicious pleasure (Batman stopped, staring at the scene before him in confusion, just as he was about to swing out to the other building). The Titans all began to glow orangey-red and cry out in pain. Starfire is still airborne, floating in thin air, over the gap between buildings. She convulses and goes limp, falling.
"Starfire!" Robin cried, he crossed the distance between them in an instant and caught her before she fell. He turned around, Star in his arms, and saw the other Titans all laid out, writhing in pain and glowing just as Star was.
"Stop! Please stop!" Robin shouted in obvious distress (the three onlookers exchanged confused glances).
"Attack Robin. It's the only way to save them. Attack with everything you've got." Slade replied.
Robin looked from one of his friends to the next, finishing by meeting Star's eyes. He was still cradling her in his arms. He became resolved looking in those eyes and he gently set her down on the roof.
"Robin…" Star pleaded weakly.
"I'm sorry." He told her an instant before he shot her with his thermal blaster.
Slade smiled in the darkness of his empty lair. He is watching on CCTV.
"That's my boy."
*shivers* Creepy Slade.
