As the plane came into land, Iris stared out of the window for a moment at the mansion which she now recognised as a place full of some of her favourite memories. She banished the thought and undid her seat belt, immediately making her way towards the front of the plane where Logan and Hank were getting read to get off. Logan eyed her cautiously, but she glanced away. Her gaze fell on Charles, who was slumped forwards slightly, a half-empty bottle of whisky beside him. She felt her heart twist with concern, but a moment later pushed her thoughts aside. She couldn't allow her thoughts to be corrupted by memories from the past, now. She had to look forwards to the future- a future that didn't involve Charles.

With a sigh, she stepped off the plane and glanced up at Xavier Mansion. It was odd, looking at it again now that she recognised it. She felt a twinge of sadness that it had been let go so much over the last ten years. Even though she didn't want to, she felt a great surge of pity for Charles and Hank.

"Iris."

She turned around, her eyes meeting Logan's. He raised his eyebrows expectantly.

"You talk to him?"

"I did," She shrugged her shoulders, attempting to keep her expression neutral, "It wasn't worth the breath."

Logan cocked his head to one side and gave her a knowing look.

"You and I both know that's not true, Iris." He muttered gruffly.

She looked away from him, "We should get inside."

Before Logan could protest, she turned around and approached the doors of the mansion, her whole body tense. She shoved the doors open, and the familiar wood was smooth against her touch. As she stepped in, memories rushed into her mind of training with Alex, Erik, Moira, Raven, Charles, Hank and Sean. Her heart contracted slightly, and she leant against the wall to steady herself.

The doors creaked open, and a moment later, Logan murmured, "Why can't he walk?"

Charles was staggering, gripping onto Hank and trying to keep his balance.

"He needs his treatment," Hank muttered, settling Charles down on a table and rushing up the stairs to retrieve the medication.

Out of habit, Iris rushed towards Charles, but froze when she realised what she was doing. She could feel her eyes stinging with tears, and she looked away. Charles was in pain, and she couldn't even help him. Because of how things had changed.

"Hey, hey," Logan stepped forwards, "Pull yourself together. It's not over yet."

Charles touched his finger to his temple, "You don't believe that."

"How do you know?" Logan frowned in confusion.

"As these go," Charles pointed at his legs, and then his head, "These come back. They all come back!"

Iris couldn't take it anymore. This was Charles in pain. She hated what he'd done to her, but she couldn't bear to see him like this.

She stepped towards him, and her gaze met his. Hurt flashed across his eyes at the sight of her.

"Charles." She murmured softly, "We need to find Raven. Logan was sent here to save us all from a future that will end in disaster, and that all links to Raven. But we can't find her without your help. Charles- you have the most powerful mind in the world. If you don't take your medication- if you instead use your mind to help us, you could save the future."

Slowly, she reached out and brushed her finger against his bare wrist. The contact sent a brief spark between the two of them. Charles' eyes widened slightly.

"I know the Charles that I knew ten years ago is still in there somewhere. The Charles Xavier that cared desperately not only for those around him but for the future of mutants too." Iris whispered.

Hank came rushing downstairs, holding a needle in his hands, "I added a little extra because you missed a dose."

Charles took the needle and rolled his sleeve backwards.

"Charles," Iris breathed heavily, "Please."

The silence dragged out for what felt like forever, before Charles' hand loosened its grip on the syringe, which fell to the tabletop beside him. Iris let out a breath she hadn't realised she'd been holding. When she glanced at Charles, his eyes were heavily shadowed. She looked away and stepped back, almost colliding with Logan as she did.

Charles' voice broke the silence, "Hank, do me a favour. Would you help me to my study please?"

Iris opened her eyes and glanced at Logan silently. To her surprise, as Hank and Charles made their way towards the study, Logan reached out and squeezed her shoulder.

"You did well, kid."

Iris nodded, squared her shoulders and followed the others into the study.

You sure about this?" Hank asked, and as Iris approached the door she realised what he was looking at. It was Charles' wheelchair.

Before she could stop herself, the image of a beach flared up around them, and Iris saw herself cradling Charles' limp body on the sand.

A whimper escaped her lips, and she gulped, trying to make the image fade away. It wouldn't, and she could feel Hank, Charles and Logan's eyes on her.

"Make it stop," She whispered, "Please."

"Hey," Hank murmured, "Focus on where you are, Iris. We're not in Cuba. We're at the mansion. Charles' mansion. The school. Remember?"

There was a moment of silence, filled only by Iris' heavy breathing. The image of the beach flickered away, leaving the dark hallway of the mansion behind.

"Iris-" Charles began to say, but she didn't wait to hear him. Instead, she fled. She ran out of the doors and towards the trees, ignoring everything else. She ran until she couldn't feel anything any more, until her chest was heaving and until she fell to her knees with a scream that echoed through the trees.

In the mansion, Charles sat in his wheelchair as Hank pushed him down the corridor. Suddenly, he heard an agonising scream from outside, and he closed his eyes, dropping his head silently.

"What have I done?"
