Siren Alley

Omega slowly opened his eyes to see Iota looking down at him with a surprised expression that quickly turned to joy, he was laying on her lap as she held him, her glowing eyes widened as she smiled. He noticed the dried blood around her mouth, nose, and ears. He figured he probably didn't look much better, Iota bent down and layed her forehead to his as she squealed happily, she showed him an empty vial with a few drops of ADAM in the bottom, Iota quickly removed the cork and lowered the vial to Omega's mouth when he stopped her. He shook his head and moved her arm to her own mouth, Iota smiled before she drank the last few drops. Omega sat up slowly still stiff from the previous battle, Iota handed him his half of the food she found inside the furniture store and the two Protectors began eating in silence, when Omega finished his meal he struggled to get to his feet, Iota saw this and quickly took his arm to help him. The Male Protector balanced himself before standing up straight, Iota walked to a nearby corpse and picked something up, Omega inspected the broken harvester on his arm now missing the needle. He knelt down and unstrapped the large diving knife from his boot and snapped the latches on his left arm for easier access. Iota walked up to him and handed him both halves of his broken helmet with a worried look on her face, Omega inspected the helmet with his trademark annoyed expression before tossing the useless object aside, Iota then picked up her heavily dented helmet and looked it over, she could see holes all throughout it where the dents had stressed the metal too much, and the large gaping hole in the back where Wallace had hit her with his wrench, she threw it to the ground. The last thing she needed was a bullet to go through one of the holes and bounce around inside her helmet, Omega began searching through the Splicer's pockets for anything useful when he noticed a Tommy gun to his right with various upgrades, He tilted his head and looked at the weapon. The Protector hated guns, only the weak used them, only cowards, besides even if he wanted to use one he had no idea how to operate one. He would stick with his large combat knife instead, it was familiar to him, and he was well versed in operating it.

After the Protectors finished gathering what meager supplies they could find they headed out to continue their tedious journey, Omega looked to Iota who was staring at the butterfly pendant he made for her, he put his hand on her shoulder, she looked at him and smiled. After a few minutes of walking the Duo stopped to look at a map of Rapture, Omega unsheathed his combat knife and scratched an "X" on all the tunnels and Bathysphere stations that were unusable, Iota watched curiously as he traced out their best route with his knife, Siren Alley was just ahead of them so he tapped the board with his knife then began tracing the path to Dionysus Park, and finally Fontaine Futuristics which was directly above Persephone, Mother's Headquarters. Iota scrunched her eyebrows in annoyance, she had already come from Percephone when she set out to find Omega weeks ago, the only difference was she had a fully functioning suit to swim to and from, now they had to travel all the way back to Fontaine Futuristics for repairs, the whole process was enough to make her want to pull her own hair out. Omega circled Siren Alley, Dionysus Park, and finally Fontaine Futuristics with his knife and looked to Iota. The Big Sister looked back at him and nodded confirming she understood the route they would take.

Siren Alley was home to all manner of business, from flesh, to narcotics, and even human trafficking, in Rapture a man was not constrained by morality and was free to seek out any and all business ventures that could earn him money, even the lowest of crimes were accepted if they could generate profit. Rapture's Red Light District was a place for men and women to blow off steam, mainly through sexual exploits though that wasn't the only form of stress relief offered in Siren Alley.

The Two Protectors entered Siren Alley and began walking through the Streets, Iota was looking at the red lights hanging around the district wondering why they were red instead of another color when she heard voices coming from a nearby window. The two Protectors crouched and began sneaking toward the noise, when they were on both sides of the window Omega unsheathed his knife as Iota readied her Harvester. The duo peeked inside the room only to find it empty, the noise was coming from a TV with a black and white movie playing. It was a scene of a Man and woman, Iota watched as they hugged, then connected their lips, Iota's face turned a light pink as she continued watching with great interest. Omega kept his knife ready and began searching the area for whoever left the TV on, Iota's eyes stayed glued to the TV as the Man began rubbing his hands on the Woman's hips, up her stomach and to her chest, her heart began pounding for some reason and she leaned in closer for a better view. The Woman slipped out of the top half of her silk robe, she began moaning as the Man messaged her breast, Iota's face took on a Crimson color as she looked to her own, the inside of her suit was starting to heat up. Suddenly she heard a sharp whistle and jumped from the sudden noise breaking her concentration, she looked to the source of the noise to find Omega crouching over a corpse with his knife in it's head, he yanked the knife out and wiped the blood on the arm of his suit before returning it to it's sheath. Iota took one last look to the TV before sighing, she really wanted to see the rest of the movie, she then stood up and began jogging over to her Partner, when she reached Omega her face was still slightly red and she was starring off at nothing clearly lost in thought, Her Male counterpart stood up putting his hand on her chin lifting it to make sure she was all right. Her breathing was heavy, when he touched her she jumped a little when she felt a shiver go down her spine and her hair stand on end.

Omega raised an eyebrow when he felt her jump from his touch, that's when he caught a whiff of her scent, it smelled sweeter than usual. When his glowing eyes met hers she looked to the ground sheepishly, Omega put his nose to her neck to take in more of the alluring aroma. Iota began breathing more heavily, she put her hand on the back of Omega's head and tilted her neck for better access, when she did her heart started racing,she had never been this close to Omega before, sure they had been close but this situation was like nothing either of them had ever experienced. she was feeling a mixture of excitement, fear, and joy all at the same time. Omega could see Iota was shaking and breathing heavily, Her scent was intoxicating and the longer they stayed in that position the stronger it got, He ran his nose down the Female Protectors neck and she let out a low purr like screech. Iota gasped sharply at the noise she had made causing her face to blush uncontrollably. Omega could feel the blood rushing through his entire body as his Adrenaline surged.

"does Dad know about this?" a voice questioned with a whimper.

The Protectors slowly looked to their left to the other side of the street only to find a Splicer starring wide eyed, the Man was wearing a dirty white suit and looked like he had seen a ghost.

"I don't want two Birthdays!" he shouted as he pulled out his knife. Iota began growling and pushed Omega out of the way as she started stomping toward the Man, Omega simply crossed his arms and leaned up against a wall to observe. The Splicer took a swing at Iota only for her to catch his arm, she pulled it up snapping the bone in his forearm, the Man screamed as she stabbed her Harvester through his chest repeatedly. The Splicer coughed up blood, adding to the collection of dried dirt and blood on the Female Protector's face, Iota wiped the blood out of her eyes as she threw the body aside, serves him right for interrupting she thought as she growled at the corpse.

"Hey big Boy got a few minutes?!" The duo heard, Omega looked to his left to see a Female Splicer running toward him wielding a board with nails sticking out of the end, The Male Protector stopped leaning on the wall to face the new threat, as the Splicer reached him he balled his fists and extended his right arm hitting the Woman square in the face, the Splicer crashed to the ground with a thud, Omega looked down on her before raising his boot and stomping her face in. Iota sighed with disappointment as Omega started walking down the street and she quickly ran up to walk beside him, the two Protectors continued walking in silence until Omega looked at Iota. She stopped walking to give him her attention, she couldn't help thinking about their earlier activity, it was... nice, she came to the conclusion. Omega tilted his head and pointed to her throat making a deep screeching hum, Iota scrunched her eyebrows with confusion until he did it again, her eyes widened when she figured out what he wanted, she smiled and began humming. Omega gave her a nod and started walking again, Iota didn't know why but this made her very happy, he actually liked the sound of her broken voice.

Just before the pump control station that Simon Whales transformed into a cathedral, Iota stopped and tapped Omega on the arm, when the Protector looked over to her she was shuffling back and forth. She pointed at a sign on the wall that had the universal symbol for bathroom, Omega nodded as he crossed his arms and leaned up against a wall to wait for her. Iota darted around the corner and into a bathroom, she was thankful she didn't wet herself trying to get her suit off, after finishing her business the Big Sister exited the bathroom, she started to walk back to Omega when she noticed a sign above a door down the hall. Iota could see the word "Lamb" in the sign, when she saw this she walked to the door and pushed it open, inside the room was a desk, filing cabinets, and a single picture of young Eleanor on the desk. There where papers scattered everywhere as if someone left in a hurry, Iota walked behind the desk and picked up the overturned chair her Mother had once used, she noticed something sticking out of one of the desk drawers, when she opened it she found an audio tape with the symbol for "Omega" and the number "2" drawn on the side in Crayon. Iota tilted her head before stuffing the tape in her utility belt, after looking around a bit more she heard the door creak and jumped ready to fight the intruder, Omega stood in the doorway with an annoyed look on his face, the Female Protector looked at the ground remembering she didn't tell him where she was going. Iota made her way to her Brother when a horrible scream echoed from the hallway, Iota froze in place when she heard the agonized scream and Omega unsheathed his combat knife, both Protectors knew that scream, they also knew how under equipped they were for dealing with it.

The Male Protector slowly and quietly closed the office door, heavy footsteps started growing louder until they shook the ground beneath the two Protectors, Omega motioned Iota over to him with his free hand and when she arrived they crouched beside the door under the office window. They heard another pained scream, this time much closer and a bright pink light was shining down the hall, Omega peeked his head just over the window seal far enough to see, when he did the light moved in his direction and he quickly ducked back down, Iota's heart was pounding, if the rogue Alpha Series found them would they be able to kill it? She readied her Harvester just in case. The footsteps got closer until they could feel the Monster was right outside the Office, it's bright pink light shining through the blinds illuminating the room showing dust floating through the air, Iota wasn't sure if she was even breathing anymore, she looked to Omega who was moving his fingers on his knife ready to attack if the beast decided to break in. She could see sweat collecting on his brow, that's when she noticed his other hand was open and dust was floating around it. She quickly looked around the room until she figured out what he was doing, on the filing cabinet in the back of the room was a fan at a ninety degree angle with it's bottom barely touching the cabinet, Omega must have used his telekinesis when the Alpha's heavy footsteps knocked it over. If not for his quick thinking she was sure the abomination would have heard the noise and crashed through the tiny room. Another thunderous scream filled the air making Iota close her eyes for a second, before the pink light turned away from the room and started walking off in the opposite direction, once the Protectors were sure the Monster wouldn't hear them they both gave a sigh of relief, Omega pulled the floating fan over to him and sat it on the ground before standing up and wiping the sweat from his face.

Omega slowly opened the Office door still holding onto his knife and peeked down both directions of the hallway, when he was sure it was safe he stepped out and sheathed his blade then motioned for Iota to follow him. His partner cautiously peeked out of the office and started walking beside her companion, luckily the Alpha headed back in the direction they had come from. Rogue Alphas were notorious for their unpredictable behavior, especially in combat, with damaged armor, no helmets, and dwindling medical supplies, attacking one would most certainly prove fatal. The risk definitely outweighed the reward, sure they could probably kill it, but they had the luxury of avoiding the unnecessary conflict. Iota wondered what Mother would have said had she seen the two Protectors choice of action, would she call them cowards, or traitors, or maybe she would praise them for their quick thinking and safe judgement? She didn't know, because Mother wasn't watching over them. Iota gave a small sigh looking to her Brother, he always had a determined aura about him, always so strong, even in the face of certain death, even if the odds were so far against them he would still fight. She began to wonder if anything could truly break him and her mind started to wonder further. What would he do if something happened to her, would he still end his own life now that they had learned of the surviving Little Sisters? What would She do if something happened to him? her stomach sank at the realization that she had no other plan after finding Omega, he was her last hope at finding their missing Family. Her chest tightened at the thought of losing him, she didn't understand the feeling of fear until she had returned to Rapture and learned of the Family's disappearance, but she had been feeling the dreadful emotion more and more recently. Iota pulled her golden butterfly Pendant from her suit and gazed at it lost in her thoughts.

Omega looked to his Partner's worried expression, if only there was a way to ease her troubled mind, but he knew better than anyone it would take answers, and that was something he simply didn't have. Omega's mind flashed back to the day before Delta's Rampage.

...

Omega stood in Lamb's office in Percephone, he had been summoned for a mission of particular importance. "Subject Omega, you have had an abundance of success in your hunts recently." Sofia gave a slight smile to the armor-clad Protector, He nodded to her in confirmation. "you have taught so many that taking ADAM is stealing from the Rapture Family, but there is another more pressing matter I need you to investigate." Lamb said as she turned a TV monitor on in the corner of her office. Omega tilted his head curious as to what the mission might be, Lamb stood from her seat and walked over to the monitor, Omega quickly joined her. "A Little Sister has been tampering with the Security cameras in various locations over the last few days, like she's trying to hide something from my view. She is astonishingly clever when it comes to staying out of sight." Lamb pushed a button on the monitor and four pictures appeared on screen, each showing a Little Sister just out of frame. "I feel someone else is at work here, all of the cameras in the Adonis Luxury Resort have been taken offline, and some in The Atlantic Express Depot as well. I want you to find the culprit, this "Rogue" Little Sister and bring her to me for questioning, am I understood?" she asked turning the monitor off. Omega nodded, placed his hand on his heart and bowed respectfully before exiting the room.

The Male Protector started his search at the Adonis Luxury Resort first, since that was where the security blackout had been focused, if there was anything being hidden from the Family, he would know of it. Omega entered an old dining room with a large window on his right, he looked across the ruined room at the many misplaced tables, chairs, and decorations when he noticed movement at the top of the stairs. He could hear the pattering of bare feet and saw a door close on the second floor, Omega started sprinting to the sound before leaping onto the balcony of the second floor, when he walked through the door that had closed he scanned the room, aside from a few flickering lights and a leaky window he found nothing amiss, until he heard an elevator ding down a nearby hallway. The Protector took off sprinting again, when he reached the source of the noise he faced a closed elevator, looking up he could see the floor counter going down, the arrow was descending rapidly toward the basement. Omega began prying the heavy doors open until he could squeeze through, when he had opened them enough he jumped into the elevator shaft and gabbed onto one of the grease covered support cables and began sliding to the bottom. When he reached the elevator he kicked the service hatch and jumped down landing inside facing the open doors. The annoyed Protector stepped out of the car into the Resort Basement, the room was pitch black, the only light being that of the glowing red slits in his helmet. from the back of the room Omega heard laughter and began walking toward the eerie sound, suddenly the lights flickered on. In front of Him was a large vault with the door slightly open, Omega tilted his head as he peeked inside, around the floor was scattered money, and coins, but the most peculiar thing was the red wagon in the middle. Omega stepped into the large vault to inspect it, he tilted his head when he saw the various toys, and jars of lightning bugs inside. In the middle of two jars was an audio diary, as he leaned over to take it he heard the door lock behind him, the Protector turned around only to see that it was completely closed. Omega began screeching and beating on the heavy steel door. He then backed up and threw a telekinetic blast at it, it only caused the paper money to fly into the air and rain down around him, he took a few steps back and concentrated all of his strength into one large ball of telekinetic energy, he pushed both hands out with lightning speed sending the shock wave into the door. The mighty steel door only shook slightly as the metal in the center bent a few centimeters, Omega let out a howling screech of rage quickly learning that the vault amplified his call to a defensing level. The Protector held the sides of his helmet as his vision blurred, when his senses returned the Brother took one last look at the door and sighed. Omega remembered the wagon in the room and walked over to inspect it, there were various items ranging from food to small toys, and paper branded with crude drawings of him, Big Sisters, and Big Daddies. What Omega was most interested in though, was the audio log in the center.

...

Omega's mind was brought back when he heard Iota give a screech, knocking him out of his daze, he looked to his partner as she held a concerned expression. Omega waved it off as nothing, and Iota pointed ahead of them, Omega could've spit from frustration at this point, though he should be used to problems by now. Ahead of the two Protectors was the Pump Control Station Simon Wales had converted into a makeshift Cathedral for the Family. Down the flight of Stairs before the two Guardians, they could see a flickering light and dark water bubbling from the top of the stairs, the Protectors made their way down to the water and stopped just before the flickering light. With the busted light above the water the reflection made it impossible to see into the liquid. Omega reached down to cup some water in his hand, he brought it up to his nose and smelled it, just as he was about to taste it for salt Iota grabbed his wrist and shook her head back and forth with a worried expression, she then pointed to the water, Omega looked to the water to see a corpse emerge from the dark liquid. The Male Protector looked to his hand and poured the tainted liquid onto the floor, Iota reached down and pulled the water bloated body onto the stairs, when she did the trapped air inside the corpse spread through the air causing her to gag, both Protectors covered their noses as the nauseating odor only grew in the confined space. Omega pulled Iota to him before using his Winter Blast to freeze the corpse completely, when he did Iota used her telekinesis to force the odor out of the staircase, the duo took a moment to catch their breath.

Omega looked to one of the many overhead pipes that was leaking furiously, he looked up and caught a few drops in his mouth. It wasn't salty, which meant that the Pump Control Station was flooded with clean drinking water, instead of a breach in the structure. Omega looked to his Partner who was sitting on the stairs holding her head up with her arms resting on her knees, she looked bored he thought as he gestured for her to wait there, the Girl's expression quickly changed to worry as she pointed back and forth between them wanting to come with him. Omega shook his head as he pointed to himself, then his eyes, then to the water and finally back to where he was standing. Iota knew he was just going to scout it out but she was afraid something might happen to him. The Male Protector put his hand on her shoulder and sat her back down with an annoyed look on his face, he then gestured for her to keep an eye out at the top of the stairs. Iota gave a hesitant nod, as she watched Omega step into the black frigged water, take a breath and dissapear underneath, she felt uneasy about the whole situation, this was the first time they hadn't been together since she found him, she couldn't see him or hear him, and there was no way of knowing if something went wrong, what if he didn't come back? what if his leg got caught in rubble and he drowns? The Sister was about to jump in and follow him when she heard an all too foreboding sound emanate from the top of the stairs, the deep tormented scream of the Alpha once again echoed through the halls.
