"Long time no see Callie," The professor said as she walked in to his office with Storm and Logan.
"I suppose it has, I need you to find my sister," She said, standing behind a chair in front of the desk.
"I know, I need you to let me read your mind first. You're sister, if I am correct, hasn't come in to her mutation yet. I can't connect to her unless I connect through you," He explained, leading her to a lift that opened straight in to the office.
Callie followed without questions, this man was the only route to her sister and she wasn't about to annoy him.
"So Callie, your abilities, how have they developed?" The professor asked, breaking the silence.
"Sorry, what?" Caller asked, her thoughts having been on her sister.
"Your powers, how are they?" He asked again, smiling as the lift opened and he led her out and down a very clean looking corridor.
"Fine I suppose, they haven't really changed much," She said as they reached a door the professor had to open.
"Good. This, Callie, is cerebro, now I need you stand nearby and concentrate on your sister, as hard as you possibly can," he said, wheeling in with her behind him.
Callie held a picture of her sister in her mind and concentrated so hard that she could almost hear her laughter and smell her hair. Apples. Her hair had always smelt like apples.
"I've found her," The professor said after a moment, turning to Callie who was wiping away a few tears, "you care a lot for your sister, don't worry, we'll get her back." He patted her on the arm in sympathy before leading her to the jet where the others were waiting, fully clad still in their black leather.
"You have the coordinates. Go," The professor said, looking at the others.
"You're staying here," Logan said as Callie moved to join them.
"She's my sister and she'll be scared. You're gonna need me if you have any chance of getting her to move," Callie replied, walking straight past Logan and on to the jet.
"Callie, at least put something on you can fight in on the way," Storm said, as she chucked Callie a uniform that looked to be about her size.
"Does it come in a different colour?" She asked, receiving a look from Scott before adding, "I was kidding," and going to change.
An hour or so later they landed and offloaded from the jet. The suit Callie had on seemed to fit quite nicely and she couldn't help but notice the look Logan gave her, her hair now neatly tied back.
"We'll take care of everyone, you find your sister," Logan said to which Callie nodded as they headed in.
As soon as they entered what appeared to be Stryker's base they were met by one of the few people Callie didn't want to see.
"Taking in humans now are we as well as animals?" He said, making Logan growl.
"I'm afraid you picked the wrong people to mess with," Storm said as she raised a storm inside the building, distracting everyone whilst Callie slipped past them, one lone person noticed her, heading straight after her.
"Hope she can fight," Scott said before they launched themselves in to battle, hoping they'd give enough time for Callie to find her sister.
Callie raced down corridors, calling her sisters name until she finally heard a slight reply, heading straight to the door she shoved on it to try to open it.
"Callie!" Jessie called from the other side.
"It's me jess, hang on I gotta ope-," She started, cut off as someone pulled her away from the door and shoved her back in to the wall.
"So you didn't die, looks like you want more of a fight," The guy said, the same guy that had knocked her out last time.
"I have your number now, you won't win," she replied, launching herself at him, using the exact moves he'd used on her earlier that very day and shocking him enough for her to catch him off guard.
She took the moment whilst he recovered to propel herself off the wall and kick him round the head, knocking him out easily before going to the door. It was strong and locked and as she looked at it an idea came in to her head.
Clenching her hands she closed her eyes and concentrated, allowing herself to copy Logan's ability. Wincing as it did a single smooth claw, bone, not metal, protruded from the middle of her fist and bending down Callie used it, easily to pick the lock. Withdrawing the claw quickly she pulled her sister to her and held her tight.
"I gotcha, It's gonna be okay, now we've got to run, can you do that?" She asked, holding her sister out at arm's length. Jessie nodded and put her hands in Callie's outstretched one before running along the corridor with her sister by her side.
They came out of the corridor on to the scene of the others still fighting. Skirting round the edge, Callie made sure to keep Jess out of the line of fire and only just reached the door the same time as Scott.
"Get the other's, I've got her," She shouted to which he nodded. Logan heard and headed over to them.
"Get her out," Callie said, placing Jess's hand in Logan's and kissing her sister on the forehead so she could go and help Storm, her ability picking up the mutant abilities in the room. Because she already knew how to do it she unleashed the claws she appeared to borrow from Logan and stabbed a guy that was rounding on Storm before grabbing her and pulling her out, the two of them closely followed by Scott.
"Nice claws?" Storm asked, not entirely sure what to make of them.
"Borrowed them from Logan I guess," she shouted as they ran, heading towards the jet as she withdrew the claws, not before Stryker had seen them.
"Jess, they didn't hurt you right?" Callie asked, pulling her sister in to another hug as soon as she saw her.
"I'm fine," Jessie replied, her voice shaky as she leant in to her sister's hug.
"We're gonna go back to the school where these guys are from, okay, we'll be safe there," Callie explained, leading her sister to a seat and strapping her in.
"They don't mind?" The ten year old asked as she let her sister strap her in.
"No they don't. And tomorrow I'll make up for the awful birthday, big sis promise," Callie said, bumping fists with her sister and taking a seat.
Logan looked back at the two girls, nostalgic for a family he was sure he must have had once.
