Set two years after X-Men: Apocalypse...so spoilers

X-men does not belong to me.

Swearing up ahead.

Thirty-one-year-old Peter Maximoff was running around the mansion at his usual speed, which was around six hundred miles per hour. He was also annoying the kids and his fellow X-Men, well everyone but Charles Xavier, he always wanted his children to be who they are and not be ashamed of who they can be. Peter was most definitely a mutant who was in love with his powers and didn't care about what other mutants or humans thought of him, apart from his Father, the man he seeked the approval from had been gone for two years and for most of Peter's life. It was okay though, Peter was home at the mansion and he had a family, but his old family were coming for a quick visit.

"Peter, your sisters are here!" Jean called; Peter smiled and ran downstairs planting a kiss on his telepathic friend's cheek, "Huh, gross!" The twenty-two year old exclaimed, "you are meant to be a mature adult!"

"Ha! That is never going to happen!" A woman's voice chuckled back, Peter's twin sister Wanda stepped in and embraced her brother, "Hey Pete."

"Wanda, how's the UK treating you?" Peter questioned pushing back gently on her.

"Disgustingly, it's a rubbish tip – which I hate. It rains all summer, it snows all winter and it's sunny on the days you wish it wasn't sunny," she smiled angrily, "but I am helping people, did your Professor get my letter?"

"Yes I did, thank you Miss Maximoff." Charles said wheeling over in his chair, "How was your journey?" He asked politely.

"It was good, thank you Professor." Wanda smiled.

"Oh please, call me Charles, you two make yourself at home, just ignore Johnny if he tells you to pull his finger." He wheeled off and left the three siblings behind, Jean followed him.

"So it's true, brits age well, I thought you told me he was nearly fifty!" Peter's younger sister shouted, she slapped his arm playfully.

"He is, trust me, he is." Peter told her, "And I thought we got past the times you slammed me for no reason, you're eighteen now..." He said rubbing his arm in discomfort.

"Shut it." She muttered, "You two have fun, Mum wants me to do some shopping." She reached forward and placed a kiss on his cheek, "Talk to her about your Dad, she has a right to know." She whispered, she jogged off out of the house.

"You'll never be as fast as me Courtney!" Peter yelled.

"Shut up silver!" She said mimicking his tone, Peter shut the door.

"Same as always, a whiny idiot, but that's why I love her," Peter laughed, "Now come with me Wanda, I need to tell you something." Her brother held his hand out and she took hold of it, they both walked into his room, "Sorry about the mess, give me a second." He ran around and in less than a second he was done, "Finished."

"Why didn't you just do that this morning?" Wanda questioned.

"I'm not Mum." Peter smirked, "And I want to stay as childish as a man can in his early thirties."

"Ah, you don't change, do you?" She sighed walking towards his bed, she sat down and he sat opposite her on a chair, "I guess you want to talk about him," she stated, he snapped his eyes at her, "I'm not an idiot Pete."

"I know. Everything that happened two years ago hasn't changed. The world is still rebuilding itself, mutants are being targeted and Eric's gone silent. No one but Jean and the Professor even knew I had a twin until I told them... yesterday. I knew my friends would push me into telling him the truth and I am going to really soon! I know you want nothing to do with him because..."

"He killed people." Wanda told him.

"He also saw his Mother murdered, our Grandmother! He fell in love with our Mother, but had to leave to hunt down the person who killed his Mum. He then turned bad because our kind was treated horribly; he was wrongly arrested for the murder of JFK, who was a mutant by the way. He was then imprisoned, I got him out and I had no idea he was my Dad." He ranted, "Because Mum didn't tell us."

"She had a right not too! She's our Mother, you were nineteen when you broke him out of jail, you couldn't even drink yet! She had a right to keep it silent until you realised and pushed the information out of her! Then you went on this crusade to save him from himself! You met him twelve years ago Pete, he's done a lot of bad. He lost his Mother and killed many Mother's to get his revenge; he's not a good man." Wanda placed her palms together and tucked them between her knees.

"He deserves to be happy." Peter told her looking up from the floor.

"No he doesn't, he deserves to be arrested and then executed for all he did wrong, he doesn't even know we exist!" Wanda spat, "he will never care that we exist, how can a man like that love anyone?"

"He did, he loved this team once upon a time. Raven and Charles were his family, but he turned on them because the universe was against him." Peter felt tears brim in his eyes, he wiped them away, but his sister had already noticed them.

"Why do you cry over him? He's the villain Peter, he was never our Dad. Courtney's Dad was better than him and he was an abusive asshole!" Wanda wailed angrily, she jumped up and walked to the door, "coming here was a really bad mistake." Peter ran in front of the door and stopped her, "let me go, let me go now because I'm not going to be a part of this."

"He had a wife," Peter started, his sister relaxed her shoulders, "and a young daughter, Nina ," he placed his face in his hands, "She was five years old," Peter mumbled, he trailed his eyes back up to her face.

"Was?" Wanda questioned.

"She was murdered along with his wife, just before the events of two years ago." He finished.

"Why?" Wanda asked as her eyes filled with tears.

"From what the professor knows, a massive earthquake knocked down a metal container, it nearly killed Dad's work friend and he saved them. He then ran home to get his daughter and wife out safe; he didn't want to be a villain again..." Peter trailed off, "the police killed our sister because she was a mutant, like me, like all the kids out there! We don't deserve to die, she didn't either! If Dad hadn't done the moral thing, if he had let that man die, then our sister would still be alive."

"You sound like him, from all that footage and lies he spilt! Yes our sister died, but we didn't know her, let me go." Wanda begged, she wiped tears out of her eyes.

"Okay, just don't come back." Peter ordered.

"I wasn't planning to...if he breaks your heart, deal with it." Wanda opened the door and was half way down the corridor when she turned back, "I will always love you."

"Back at you." Peter ran and picked her up gently; he dropped her off at his Mum's; he then ran back and slammed his bedroom door.

Jean snapped her head back, "that conversation didn't go well." There was then a scream from his room, full of anger, "Should I...?" She said turning to the professor.

"Leave it to me, you're all my responsibility and I have to deal with your rage as well as your love." He wheeled past her and knocked on Peter's door.

"Go away." The man snapped, Charles opened the door and let himself in; he closed the door behind him. "I said go away."

"The mission, that we are heading to tonight, Eric's helping us." Charles told him, "Maybe it's time you tell him, it's the right thing to do."

"He won't want me," Peter said shaking his head, "He lost his family that he loved two years ago and now I'm stuck at the epicentre of it."

"You are not an emotional person Peter, you're a joker and the comic relief that the X-Men need, but Jean and I know that you're much more than that. That's just your mask because you're hiding thirty-one years of unneeded neglect, you think your Dad hates you, but Eric was eighteen when he was with your Mum and he had just escaped out of Shaw's grasp, he wasn't ready to be a Dad," he explained, "he could be now."

"Yeah, I'm a bit too old for all of that now," Peter started, "No soccer matches, or baseball games; instead I got worldwide destruction and murder, he can't fix that."

"But he can damn well try." Charles placed his hand on Peter's shoulder.

"I want him to know who I am, but my sister doesn't fucking care." Peter cursed, "What if he doesn't want to know me?"

"Tell him a story, about you..." Charles told him, "It might help him deal with the blow."
