Monday
We come down on a dark night; the rain falla intensely; each drop crashing to the ground with a roaring force. The moon was nowhere to be seen, but the glow of battle, mixed with the lightning illuminates the scene.
A very terrified looking Beast Boy is slowly baking away from something unseen; then there is a flash and a twang of metal and he collapses.
We then turn to Raven, as she flies backwards, furiously attacking her assailant, throwing every spare bit of debris, anything of substance, but it seems to have no effect as a figure in silhouette mutters something that can't be understood and a blue blast of energy fires form one of the attackers hands and to spite Ravens quickly raised shield she falls to the ground and does not move.
After that we see an enraged Starfire charge at the still unseen enemy, hurling so many starbolts it appears to be an almost constant beam, but this time we see the full extent of the damage as the attacker grabs the Alien's wrist and swings her around, holding her. The pause is only momentary as the figure, still cloaked in an unnatural darkness, switches his grip to Starfire's hair, and pulling her head back produces a knife from seemingly thin air and cuts her throat, deeply, from ear to ear.
As Starfire's body drops in almost slow motion, she coughs and sputters her last breath, but the attacker is no longer interested in her, he turns quickly to his left to face the final two of his targets. In blind rage at what they have seen, Cyborg and Robin race towards their enemy with only one thing in their minds, revenge. However, their adversary is too fast and with another flash and twang of metal…liberates Cyborg's head from his body.
Robin is alone and he is sickened, and horrified and sad, but most of all, at this moment, he is more angry than any other person on the planet, you can see it in his eyes, even though the mask. He knows he has only one chance to take this man down, for his enemy will give no reprieve, he does not hesitate more than a millisecond before charging at his foe one last time, his staff in hand. They race towards each other with inhuman speed. The assassin makes a strike with his sword but is blocked by Robin's staff, and as they pass, all his cunning, and skill show him Robin's opening and he draws the same dagger as before and plunges it into Robin's back, almost to the hilt.
There is a gasp from the latter, but drawing no breath.
Robin's usually resolute and determined expression is suddenly replaced by a look of utter shock. His staff rolls out from his hands and he staggers forward a few paces and drops to his knees. Blood is rolling down from his mouth and it looks like a read tear, he silently mouths the words "I'm sorry…" and then falls on his face.
A scream of rage erupted from Robin and he opened his eyes to the sunlight flooding his room, he was cold but sweating, and he started to remember where he was.
"Jesus!" he said "What a fuckin nightmare…" but Robin could not entirely convince himself. He had a bad feeling about today.
