Sebastian looked expectantly at the teen in front of him. The teen mouth formed an O before he responded.

" Oh yeah I totally understand! You see I am from an alternate universe where you are a superhero and I'm your friend. My names Alexander. Don't tell anyone about what just happened. " Alexander said before grabbing the items that had fallen on top of Sebastian's head.

" Wait- " Sebastian couldn't say anything when the Alexander suddenly disappeared. Sebastian rubbed his temples in annoyance and to fight off the headache that was coming.

The other Barry had to explain what was happening in the best way possible. He hoped to not stutter but knew he was going to anyways.

" Okay so Barry's assassins are coming to finish the job s-so I won't exist while he won't exist. It's l-like uh.. um. Just give me a second. Oh yeah! A win-win for these guys. They must be messing up with the time stream. " The other Barry said picking up a computer and rapidly typing through it.

" This just keeps getting crazier and crazier! " Cisco exclaimed looking at the messy lab.

" If assassins are coming we need to get Barry out of here! " Joe said looking hurriedly at the room Barry was resting.

" Great idea. I'll be back. " The other Barry disappeared in a blur before returning in a moment. " Who's going to be with your Barry? "

" I'll go. " Iris said before the other Barry ran off with her. Joe looked at the computer watching when an alert flashed on the screen. A model of the city appeared on the screen and an orange dome appeared over the city.

A rush of wind and suddenly there was the other Barry rapidly typing on the computer again. The other Barry seemed concerned at the information the computer gave him.

" Okay so the assassins made some sort of force field like dome around the city. It stopped time and is also messing up with the gravity. The force field means we can't escape until the assassins either finish the job or we finish them. " The other Barry said announcing it to everyone in the room.

" So are the assassins some sort of futuristic ninjas or something? " Cisco asked almost trailing off at the end of his sentence. The other Barry shrugged.

" T-they're actually kind of like organic robot assassins. " The other Barry answered in a shy voice.

" So can we call them Sentinels? "

" S-sure? "

" So why're they messing with gravity and time? " Caitlin asked crossing her arms over her chest. Her head was still spinning with all this new information that was being given to her.

" It's hard to run while floating in the air. " The other Barry grimaced. " They want an unfair easy fight while not causing to much damage to this universe's time. I guess they want to contain the damage as much as they can." The other Barry said picking at the bloody bandage on his forearm.

" So when is Alexander coming back? " Joe asked.

Barry slowly opened his eyes to see his surroundings. He was surprised to see that he was at home and Iris was sitting on the edge of his bed. Iris smiled warmly before helping him sit up in his bed.

" How're you feeling? "

Barry felt tired and worn out as if after a very long run. His throat was dry and his sore body was warmer than usual. As Barry told Iris how he felt she handed him a cup to drink from.

" Thanks. " Barry said before an awkward silence fell between them. He sipped more of his water gratefully before suddenly Iris lunged and Barry was in a tight hug. Barry was stunned at first not knowing what to do but then he hugged her back.

Iris almost cried when she felt her hug being returned. So many things had happened since when Norman stabbed Barry. Iris could only hug her best friend tighter as she thought at how close she was to losing him. Things were finally getting better.

Of course Iris wouldn't say how bad Barry actually looked out loud. He had a thin layer of stubble on his face and his eyes had sunken in with dark circles. His hair was a mess and his voice was hoarse.

Iris knew big things were going to happen. Things were going to change forever but Iris knew that Barry was always going to be there for her. And she was always going to be there for Barry.

It wasn't until when Alexander fell out of the portal did they start to make a plan. Alexander remembered that he made a rather undignified landing onto the floor of STAR labs but no one mentioned it. Once Alexander was out up to date he started to pace around the room before stopping. The other Barry looked around the room nervously but he remained silent.

" So what's the plan? I mean I know there are some sort of- sentinels are coming to kill my Barry and I'm not letting that happen. So what do we do to stop them? " Joe said not wanting the silence to go any further.

" You're going to have to get more ammo Joe. And a stronger gun because we need everyone we got to fight these guys. Even you two. " Alexander pointed at both Cisco and Caitlin. " I mean no offense but you guys haven't fought many things that much. "

" I can make some sort of temporary weapons but I need to know what I'm fighting against. " Cisco said already thinking of possible designs of possible weapons.

Alexander showed Cisco several models of the sentinels. The sentinels were tall about as a small lamp post. The sentinels had sleek silver bodies in the shape of serpents. Their limbs had an elegant but deadly look with the ability to transform into guns and claws. They also had artificial intelligence but actually weren't that smart.

" Alright let's do this. "

Barry listened to Iris as she spoke about what had happened over the course of the days he was in suspended animation. He was surprised and shocked at how much at had happened when he was out but at least he was used to it. It was just like another Tuesday in a weird way.

" Wow I missed a lot. " Barry managed to say at the end of Iris's explanation. After all Iris described of what he had gone through Barry really understood why he felt so horrible.

Joe watched as Cisco worked on a two small but powerful guns. The other Barry had decided to help so they can finish the guns faster. The other Barry was listening to Cisco's instructions carefully. The other Barry's hands were a blur as he worked on the guns.

Joe looked a few feet away towards Alexander who was playing on his watch. Joe walked over to him saying, " Hey can you answer a question for me? " Alexander looked up from his watch.

" if it doesn't have anything to do with the future. Then yeah sure. " Alexander said good naturedly.

Joe nodded in acknowledgement. He said, " When the other Barry arrived he looked at Caitlin in a weird way. Why? "

Alexander was silent for a moment taking in what Joe had said. He then began to speak, " Wow good question. I mean you have good eyes and a good memory. " Alexander scratched the back of his head. " What if I tell you in my universe Barry didn't love Iris? "

" What!? " Joe wasn't happy at the news but Alexander shushed him before Joe could say anything else.

" No what I meant to say was that in my universe my Barry isn't in love with Iris. He only sees her as a sister and a best friend. " Alexander reassured Joe not wanting for anyone to get the wrong idea.

" So does your Barry have something for Caitlin? Or no? " Joe asked Alexander. Joe looked at the other Barry who was across from him at the other side of the room.

" Yeah, my Caitlin and my Barry had a nice weird relationship. Until everything got so complicated it's unbelievable. It all happened after a really huge event occurred. " Joe looked like he wanted a more thorough answer. " Can't really tell you anything else. Sorry. " Alexander said as much as he could.

Alexander felt his watch vibrate and he looked down at it. His eyes widened and he yelled, " Everyone brace yourselves! " Right after he said that everything had started to float.

Cisco instinctively grabbed a table but it was floating as well. Caitlin was sitting it a chair and she gripped her seat tightly. Joe resisted the urge to pull out his gun knowing that it wouldn't help anyone. Joe only hoped his Barry and Iris were doing okay.

The gravity anomaly seemed to take longer than the first one. Alexander looked at his watch and said, " This one was longer. These gravity anomalies will only get stronger and longer as the time goes on. So I suggest nicely that we hurry up. "

It took almost an hour until Cisco and Barry were done making the guns. Joe looked at the guns noticing how futuristic they looked. Joe caught one of the guns as Cisco tossed one to him. Caitlin was surprised when she was tossed one to. Cisco kept a gun for himself.

Alexander rolled his sleeves up a determined look in his eyes. His hands began to glow a soft green but Joe knew those hands could probably do a lot more damage than people would think.

" Let's fight. "

Cisco honestly didn't think that he would one day be standing in the middle of a road waiting for killer robots to arrive to try and kill one of his friends. Cisco was nervous and was hoping he wasn't going to die.

Something moved in the corner of his eye and suddenly something silver shot something at him. Cisco managed to dodge it and shot at the sentinel that was continuing to try to hit him. His gun managed to hold off the sentinel before the other Barry ran towards the sentinel.

The other Barry jumped onto the sentinel, punching it's shoulder. The sentinel grabbed at the other Barry but he ran off of it before it's arm got to him. Cisco glanced around to see what the others were doing.

Alexander was teleporting everywhere. He teleported on top of a sentinel, his hands were glowing green, Alexander then grabbed the sentinel's head and teleported away taking the head with him. The sentinel fell to the ground with a loud thud.

Caitlin was running around avoiding a sentinel's limbs as it tried to grab her. She shot at the sentinel's arm before shooting its head several times. Alexander noticed her struggles and a glowing ball of energy began to form in his hand. He threw the ball of energy at the sentinel's chest. The ball of energy went straight through the sentinel's chest.

Joe was keeping his ground making sure to keep a sentinel several yards away from him. The sentinel was battered from Joe's onslaught but it kept pursuing the detective.

Cisco drew himself from his thoughts and continued to shoot at several sentinels. The other Barry was close by always taking a sentinel down as fast as he could.

Alexander looked down at his watch. His watch started to vibrate madly in warning of what was coming. He narrowed his eyes at the sentinels in front of him. He was ready for the gravity anomaly to come.

Barry didn't know what was happening when Iris suddenly grabbed his arm and dragged him in a closet. He heard loud bangs and several robotic whirls from outside of the closet. He definitely didn't know what to do when he suddenly start to rise from the ground as if gravity suddenly turned itself off. He wasn't off the mark actually. But Barry couldn't keep the small gasp of surprise that escaped his mouth.

A huge clawed hand burst through the closet door and Iris screamed in fright. Barry clenched his hands ready for a fight. He launched himself at their assailant and he sent a flurry of punches into it's chest. Their assailant was a snake shaped sliver robot with spiked arms and glowing red eyes. Barry compared it mentally to a snake.

The silver snake's spiked arm caught Barry unprepared and cut his forearm. Blood spurted out of the wound as soon as the silver snake lashed out at Barry.

Iris noticed that the other Barry had the same wound on his forearm. The only difference was that the other Barry had a bandage in his forearm.

The silver snake went after him but Barry dodged it. Barry managed to get to the couch which was currently floating in the air like him, he threw the couch towards the silver snake. The silver snake made a noise of anger before moving around the couch and lunged at Barry.

Barry then sent a flurry of punches at the silver snake's head before sending a powerful kick to it's abdomen. The silver snake didn't get to do anything before it stopped functioning.

A teen was only walking when everything started to float. He let out a gasp of surprise when he couldn't seem to touch the ground. He looked down to see he too was floating. He looked at something moving in the distance. He saw a silver snake like monster fighting some guy he didn't know. The guy had long black hair and had a gun in his hand.

" I need help here Barry! " The guy yelled for help. The teen didn't know what was happening but he knew that it wasn't normal. But the teen was used to strange things. The teen even saw his mom in the distance too. She was screaming for help. Anger flared through the teen before he blacked out.

Cisco tried to fight off the sentinel but found it hard when he was floating. He remembered when Alexander told them that the gravity anomalies were going to get stronger and longer but he never really knew that it was going to make everything so freaking difficult.

" I need help here Barry! " Cisco yelled for help. Suddenly the other Barry appeared in top of the sentinel in a flash of green light. Alexander must've teleported him there. The other Barry punched the back of the sentinel's shoulder before the sentinel tried to grab him.

Alexander was being surrounded by several sentinels. One of them was trying to shoot him as he teleported to avoid their attack. He heard a scream of terror and he looked at who was screaming.

In the distance Madeline was lying on a street her arms were in front of her face in a futile attempt to protect herself. A sentinel was looming over her and was about to kill her.

Alexander was about to teleport over there to save his other mother but a two sentinels grabbed him from behind. He tried to teleport away but something was stopping him from doing it.

" No! " Alexander shouted in terror. He was going to lose his mom all over again. Everything started to fall to the ground. The gravity anomaly was over.

Madeline was terrified, her hear was beating at an impossible pace and she felt like she was going to have a heart attack before this snake thing killed her. As the snake thing got closer she screamed.

She thought she was done for until a green flaming hand went right through the snake thing's chest. The snake thing's body gave a groan of protest before flaming hands grabbed it's head. The flaming hands flared and the snake thing's head started to melt. She never got to say thank you to whoever saved her. The person who saved her was gone. Madeline only saw a flash of green light before she ran away to the safety of her house.

Caitlin was never supposed to leave the group but she was pushed away from them by a persistent sentinel. She never saw the arm that sent her flying into the air. She landed on the ground with a grunt of pain. She cried for help but knew that no one could hear.

" Hey! " A shout sounded from behind the sentinel. The sentinel turned around to see a green flaming fist going towards it. The flaming fist hit it's mark and the sentinel staggered a few feet until lunged at the owner of the flaming fist.

Caitlin stared at her savior as he fought against the sentinel. She couldn't get a good look at her savior's face but knew she had to help him. She grabbed her gun and started to shoot the sentinel's back. As both of them defeated the sentinel together Caitlin got to see her savior's face.

" Alexander? " Caitlin managed to gasp out as she looked at the teen in front of her.

" How do you know my name? " The teen demanded his hands still on fire with dangerous green energy. Everyone who knew him was supposed to think he was dead.

Caitlin looked at the teen. This other Alexander had dirty hair and face with cracked glasses. He had dirty clothes as well. This Alexander was different than the Alexander she knew. He looked angry and he looked like he was ready to hurt anyone he needed to.

There was suddenly a whirling sound as the sentinel behind them started to vibrate.

" What's happening? " The other Alexander said as he watched as this strange snake thing started to vibrate. Suddenly the snake thing exploded, and the other Alexander was blinded by the bright light the explosion caused.

Caitlin looked up in horror to see some sort of mini black hole appear right where the sentinel was. She realized that it was sucking her in. She turned around and grabbed the thing closest to her. The closest thing to her was the other Alexander.

Her grip on the other Alexander was slipping and her heart skipped a beat in fear of her getting sucked into the black hold. But the other Alexander suddenly grabbed her arms as he too fought the pull of the hole.

" Please don't let me go! " Caitlin pleaded with tears in her eyes. The other Alexander didn't say anything but his grip got stronger at Caitlin's plead.

The black hole suddenly got stronger and Caitlin lost her grip on the other Alexander's arm. She screamed as she was sucked into the hole.

" No! " The other Alexander yelled before he teleported towards the black hole in an attempt to save her. But the black hole disappeared as soon as Caitlin entered it.

He didn't know who that was but felt a sense of loss anyway. The other Alexander didn't know what to think. Weird things were happening and he didn't know what to do. He didn't know how this lady even knew his name. It was strange, he wasn't called Alexander in a long time. People usually called him Alex.

Alex heard someone walk behind him and he whirled around. Suddenly Alex was face to face with himself.

" Who are you? " Both Alexander's demanded.
