Dialogue the First

Her face, beautiful and unfamiliar, all the scars gone. Rebuilt. Dominating the room with her presence in a way she never had before. Purposeful. Alluring. She didn't look for anyone when she entered. She chatted up a man at the entrance, left him waiting. She ordered a drink, her curves evident as she leaned against the bar, even beneath the simple outfit she was wearing. It took him a moment to realize she was posing.
She finished her drink, stalked through the dance floor. Ignored some people, visibly amused by others. Stopped by an attractive Asari. Danced near the Asari. Powerful, graceful. She was definitely showing off. When the song ended, she walked off, leaving the Asari staring after her hungrily.
She walked through the club. A man stopped her, his eyes desperate and pleading. Her mask slipped a little as she listened. She nodded, glanced around. Stunned, he watched her walk up to the table where his target was talking to a woman. A short conversation that he couldn't hear, and the woman at the table got up and walked away. He watched Serenity casually leave as well. The team immediately started reassessing the plan. He tuned them out, kept his eyes on Serenity.
She walked back to the bar, joked with the bartender. Had another drink. Then somehow talked the bartender into giving a free round to everyone in the bar. She smiled enigmatically over her glass, and started to walk away.
He hadn't seen the Asari, and he had no idea how he had missed her. She was tall for an Asari, strongly and elegantly built. This was obviously what Serenity had been waiting for. The Asari placed herself just within Serenity's field of vision, and waited. Serenity finished her drink, approached the beautiful Asari. They walked together to the private booths, Serenity trailing behind. They sat down, almost directly beneath him. He could hear almost every word of their conversation.
He heard her casually suggest Hallex to the Asari. Talking about a horrible band that depended on sensory overload and addiction. About the vile sculptures of the mentally diseased Forta. Was this really Serenity? But then, he'd never heard an Asari talk like this either. Morinth, she said her name was. Morinth seemed to be hanging on Serenity's every word. At one point, Morinth moved as if to leave, seeking to recover her self-control after Serenity had dropped a particularly sexual double entendre. Serenity leaned forward, put her long legs on the other side, blocking Morinth's exit. Morinth stared at her legs as she wanted to devour them. Morinth smiled at Serenity, slid a hand into the baggy pants. Caressing Serenity's legs openly.
He groaned silently at the sight.
"We're alike, you and I. We want the same things." Had Serenity's voice always been so dark? And why didn't this make her less beautiful to him? Why did he still want her as much as he ever had before?
Morinth suggested leaving the bar, returning to her apartment. He hated the smile Serenity gave her in return. Hated the dark purr in her voice as she pointed out that Morinth would have to take her hands out before she could stand up. Morinth laughed, dark and joyous. Pulled her hands away. Licked sweat from her fingers while Serenity drank in the sight. They stood, Morinth wrapped her arm around Serenity's waist. Serenity drew Morinth to her, pressed their lips together.
A soft whisper that no one else should have been able to hear. "Just giving everyone a glimpse of what they're not good enough to get."
Their bodies seemed to melt together for a moment. Black leather against rough denim. Soft blue curves against her lithe muscles. Serenity pulled away first, a confident smirk on her face. Morinth... he'd never seen anyone with eyes so dangerous before. Wild. Evil. Her hunger for Serenity went beyond mere sexual desire. But Serenity couldn't see that in her eyes as Morinth led her out of the club.
He demanded information on the Asari with evil eyes, and ran through the ducts to try and catch them before they got away.
"There is a possibility that the Asari might be a serial killer. We've been requested to stay away from her." He heard the command, but couldn't obey it. Forced them to give him the location. Raced through the alleyways of Omega, up the side of an adjoining building so he could see her again.
He was in time to see Serenity pick up the bottle of Hallex.
"Are you sure you don't want your mind clear for this? I know I do." Morinth's voice, dark, sweet, inviting. "Come sit by me."
Serenity smiled, walked forward. Leaned over, physically invading Morinth's space, her arm on the couch, her body invitingly poised over Morinth. The Asari reached up slowly, with an amazed smile, pulled Serenity to her. They kissed again, Serenity leaning in, possessive and demanding. Morinth wrapped her arms around Serenity, softly whispering dark things. Serenity growled something that made Morinth toss her head back in passion, her face turned away. Serenity buried her face in the Asari's neck, whispering words that he couldn't make out. Morinth's face changed, gasping with passion as Serenity's hand slid down her body, caressing. Morinth's face flushed, her eyes darkened. Morinth shook herself and with a visible effort regained her self-control.
In mockery of Morinth's earlier act, Serenity raised her hand to her lips and licked her fingers clean. Morinth stared at her, almost mesmerized.
"You are the most amazing creature," Morinth hissed. "If only..." she paused, drew Serenity into another fiery kiss. "I want you." She stared into Serenity's smoldering green eyes. Shifted her body, moved so she was over Serenity. "Tell me you want me. Tell me that you would do anything for me. Tell me you would kill for me." Her eyes were glassy black, burning orbs.
He couldn't see Serenity's face from his vantage point. A chill burned through his soul. Would he be able to reach her in time?
Suddenly Morinth drew back, shocked rage on her beautiful face. "What? Oh no... you..." Serenity's mocking laugh as she pulled away from Morinth rippled across the room and through the half-open window.
The door burst open, and another Asari, this one in red battle armor, burst into the room. Serenity flung herself to the floor as bolts of biotic energy ripped across the room. Morinth was plastered against the window, shrieking in fury. Morinth flung a blast of her own, almost forcing the newcomer to the floor. The two Asari tore the room apart in their rage, throwing each other back and forth. Serenity hovered on the edge of the battle, waiting for the right moment. As Morinth gathered herself for another devastating attack, Serenity tackled her, pulling Morinth's arms behind her and leaving her completely exposed. Morinth was knocked flat, and Serenity thrown aside. Serenity picked herself up, the strange Asari walked forward, put an end to Morinth forever.
In shock, he realized the Asari in red armor had almost the same face as Morinth. They could have been sisters. Probably were. The Asari in red stared sadly down at Morinth's body.
It had been a trap, he realized. Serenity had laid herself out to capture Morinth. He sighed in relief. Such a very convincing act. He shook his head at his own lack of faith, he should have known that Serenity would never fall so far. He drank in the sight of Serenity's face, restored to her normal resolute sweetness. Watched her as she moved. She was talking to the Asari, comforting her.
He felt himself freeze as Serenity moved closer, one gentle hand touching the Asari's shoulder. Serenity's eyes were warm, hoping, desperate. The Asari was too wracked with internal grief to resist, and it wasn't until Serenity's hand had gently stroked her cheek that the Asari pushed her away. "Please, Shepard. You have been ... a good friend to me. Let us go now."
"Anything you need, Samara."
It was an indescribable pain to see the hunger in Serenity's eyes as she watched the Asari - Samara - leave the room. Without a single glance at Morinth's body, Serenity followed.
He buried his head in his hands, awash in futile rage and almost insane jealousy. He waited until she had left the room before reporting that Morinth had been killed by the Asari in red armor. He stood up, holstered his weapon. Wondered if he should have just taken the shot when he had the chance. Wondered who he would have been aiming at if he had.
