A/N: Thanks for the reviews, I promise this chapter will be longer - I don't own X-men but I do own the twins.

We're the X-Men

The man dropped the woman to the ground, turning and looking at the twins. His laugh was enough to make Erica take a small step back and Erin was close to doing the same until he saw a familiar mark on his neck. It was a tattoo that had become popular for mutants to get, a form of unity, although Erin and Erica had thought it stupid to brand themselves, not that they didn't have tattoos. Erin grinned at the guy, glancing back to Erica and nodding. If he was a mutant then there wasn't any problem with them using their powers, carefully. Looking the guy over, Erin ignored the crowd beginning to thin and those that were left were watching them while dialing on their cell phones. The woman that had been attacked by the man was still against the wall, looking at both the twins and the man that had just threatened her life. It probably wasn't a good idea to take the guy on, but there were two of them and only one of him, right?

Just as the man began to charge them Erica stood in front of her brother and stuck out her hands, hitting him with an unseen blast although the glass around them shattered like hit with a high pitched sound. The man stumbled back, growling. He blinked reaching up to his right ear; pulling it away he'd look at it and stare at it. His hand had blood on it; glaring back to Erica he'd snarl before charging again, faster than before. Erin pulled her out of the way, catching the man's blow instead. Both of them were sent onto the subway tracks, the man pounding Erin's head on one of the rails.

Erin looked up at him in a daze, vision blurry, although the man's growl reached his mind perfectly. "What were you sayin', kid? Pick on someone my own size?"

"Yeah…exactly what I said…" Erin looked at him and smiled slightly, although his vision still hadn't cleared yet. Grabbing the man's shirt with one hand he'd punch his stomach with the other, a loud 'boom' sounding off. The pain caused the man to grip at his stomach, finding that his shirt had been burnt away and his stomach was also burnt and bleeding. "Don't pick on humans…"

"Stupid kid!" He growled and grabbed Erin's face and slammed it against the metal track again, and again. He only stopped when a loud sound ripped at his ears, or was it his mind? It sounded like a group of people screaming, the sound of it rose in pitch until it reached to the sound of an unbearable shriek. The man screamed as he held his head, this was louder than her first attack and this was enough to cause him to back away from her dazed brother. "The hell?"

Erica glared at him; it was all she could do considering the fact that she couldn't speak. As she continued to use her powers on him she looked at her brother, seeing him still slightly dazed as he laid there on the tracks. She could only hold the guy off for so long and the sound of police sirens were growing in the background, but what other sound was growing…her eyes widened as she looked to the end of the tunnel, the train. 'Erin! Get up, the train's coming! Get up!'

Erin sat up holding the back of his bleeding head, he looked over his shoulder and indeed the train was coming. Standing as quickly as he could his attention focused on the man again, he seemed like he only cared about making the noise Erica was torturing him with. Now he was torn, did he climb back up onto the platform and let the man fend for himself or did he help him. Looking up to his sister he'd shout over the sound of the oncoming train, "Erica, stop! We can't let him get hit by a train!"

She nodded the sounds stopping, causing the man to look down at his blood-covered hands and to look back at Eric. He growled, grinning evilly at Erica before charging at Erin again. Catching his gut with his claw like fingernails he only laughed when he heard Erin's scream. The train was closing in now. He growled when Erin punched him harder this time, throwing him against the wall of the tunnel. Erin had enough time to see the train coming at him before everything went black, his sister's voice ringing out in his mind clearly, 'Erin!'

(Inside Cerebro)

"Eric, I've found Sabertooth…seems like he's causing problems in the Subway." Professor Xavier turned to look at his long time friend. It still felt different, having both teams in one home and on the same side, but the change was welcome they were all able to work together now. Even Magneto himself seemed to have settled down and fallen back into the ways of the school.

"The subway…I wasn't thinking that he would come back." Magneto shook his head slowly as the two of them exited cerebro. It had been a long time since they had encountered him; Sabertooth had vanished before their battle with Apocalypse and that had been over a year.

"Logan…I need you to go to the subway, your old friend is causing problems and two mutants are there with him." Xavier stopped Logan just as he was leaving the Danger Room.

"Sure, I'll take Gumbo with me just in case." Logan huffed slightly, grabbing Gambit by the back of his trench coat. He still didn't like how Gambit was always following Rogue around like a lost puppy. "Stop flirting, bub…we got work to do."

"Bu-fine…good bye, mon chere." He waved dramatically, causing Rogue to blush and laugh slightly as the two of them left the mansion to go after Sabertooth.

(Subway)

Erica jumped down onto the tracks, ignoring the screaming people and the smoke coming from the now stopped subway train. She'd shake her fallen brother's shoulders, looking up at the man covered in metal that had stopped the train. He was now looking at her, concerned. She frantically began signing her words but when all she got was confusion from the man she fumbled for her mini-notebook and paper. Writing her words down quickly she'd hand him the notebook before trying to wake up her brother, the blood on his shirt staining her hands. The 'metal man' as Erica had so lightly called him on the paper looked her over before touching her shoulder. "It will be fine, here."

He picked up her brother carefully; looking around for Sabertooth but when he saw nothing he looked down at her. "My name is Colossus…I know where we can take him."

"Tin man?! What are you doin' here?" Gambit jumped down onto the tracks and looked them over before turning to look at Wolverine. "Gambit'll take dem back, you go get the kitty, non?"

"Sure thing bub…" following after Sabertooth's scent he'd head off down the tunnel and leave Gambit with the others.

Gambit smiled at Colossus and then to Erica, placing a hand on her shoulder he'd nod when she looked at him. Climbing up onto the platform first he'd take Erin's limp body from Colossus and smile as the big Russian helped the girl up onto the platform. Carrying Erin's body, his arm positioned over his shoulder, Gambit would cut through the crowd news crews already arriving. Colossus wrapped his arm protectively around Erica as they moved through the crowd; soon reaching the jeep that Gambit and Wolverine had driven there. Climbing into the front with Gambit he'd watch Erica out of the corner of his eye while she cradled her brother against him. He smiled slightly when he saw Erin's eyes open slightly, Erica seemed to calm down slightly, but what surprised him was when Erin spoke to her. "Gambit and…Colossus, huh? Guess…we picked a bad fight…"

'I didn't know that he was that strong…I'm sorry…' She bit her lip as she looked at him, he looked horrible and she had been the one who told him that they should have fought him.

"Its okay…you we're right, he was…he was gonna' kill her…" Erin smiled up at her before closing his eyes and resting against her. "Don't worry…I'll be okay…"

Erica nodded, watching her brother as he lost consciousness again against her. Catching a glance at Colossus out of the corner of her eye she'd look at him fully and smile. She did a simple sign for thank you and luckily he understood it.

"Your welcome." Colossus nodded before looking at her again. The metal covering his skin disappearing he'd look to Gambit, who was in turn looking at him curiously. "You and your brother…you picked the wrong mutant to fight."

She nodded, writing on the paper and handing it to him. 'He looked like he was going to kill a woman for calling him a mutie.'

"That sounds like him…" he sighed and handed her paper back to her. It was odd, he had never met a mutant before that was unable to speak but with the next generation of mutants rising who knew what kind of mutants there were.

They continued back to the institute in silence, taking back roads and off road ways to avoid being followed by anyone. Once they were there Colossus took Erin and headed for the infirmary while Gambit and Erica followed, but the professor stopped them. "Thank you Gambit…I need to speak with Erica before she goes in to see her brother."

"Sure ting, Professor." Gambit smiled at Erica before wandering off to find his Rogue.

"Erica…I'm surprised that you and your brother haven't come to this school earlier, most mutants know of us." He rolled his chair alongside her as they moved through the school.

'Erin and I talked about it, we started college here last semester…but we didn't know what we were supposed to do, I mean…with how things are for mutants we didn't know what was best…but he knows that I've always wanted to learn how to control my powers.' She looked down at the professor, surprised to see him nodding, so he could understand her.

"Sadly…no…I can't understand you the way that your brother can…I'm only reading your mind, lets just say that I'm saving trees." He smiled at her as she laughed silently. Her mind was jumbled, but with the memories that he gathered from her he understood why she felt the way that she did. "You and your brother are more than welcome to stay here, for as long as you like."

'Thanks…I'll talk things over with Erin…hopefully he'll change his mind once he sees how big this place is.' She smiled at the professor again and waved at Colossus as they entered the infirmary. Did he blush when he saw her or was she seeing things?

"Colossus, could you keep an eye on Erica and show her to a room as soon as Hank has given her brother an all clear?" The professor smiled when the tall man nodded, turning his wheel chair around to leave he'd nod to Hank and Erica before he left.

(Subway Tunnel)

Logan sniffed around, the scent of Sabertooth had disappeared a few hundred yards ago, but he wasn't going to give up that easily, he still had a big bone to pick with that guy. He had left Gambit over two hours ago and he was beginning to wonder how those kids were doing after taking on the big fur ball. Just as he was about to turn around something caught his attention, crying? Had he stumbled across the Morlocks and not realized it, no, he hadn't recognized anyone's scents. Following the sound of the crying he'd reach a dead end of the subway tunnel, but he found the reason for the crying. A young teenage girl was sitting on the ground with her knees drawn to her chest, although he couldn't see her face he could hear her tears all too well. Maybe working at the institute had caused him to go soft, but he approached her anyway although once he was close enough to her he was surprised when she laughed and threw something on the ground causing him to start gagging and coughing. Before he knew what had happened he was on the ground and everything was becoming fuzzy, everything went black. The last thing that he heard was, 'welcome back Weapon X'.

A/N: So what do you think? I hope not everyone is mad for the way that I'm making Piotr act around Erica, I think its cute. Oh yeah, Kitty and Lance are together in this fic…sorry if that ticks some people off.
