2) Good questions
Plot: Charles and Peter's little sister talk. Set during DOFP (I'll leave interpretations up to you, like whether she's the Scarlet Witch or not.)
Logan, Charles, Hank, and Peter were almost out the door when Mrs. Maximoff blocked their way with her arms crossed. "Gentlemen," she addressed the three older men politely. "Please tell me what's going on."
Charles opened his mouth to answer, but Peter cut him off and walked with his mother to the kitchen, giving the others a look that clearly said, "I got this."
The brunette glanced hastily at Peter's little sister, who was hopping down the stairs in her princess attire. "Sweetheart - "
"Where are they taking, Peta?"
Mrs. Maximoff sighed tiredly and mustered up a smile. "Nowhere, honey. Go... Go play with your dolls." She went into the kitchen with her son. Instead of playing with the same old dolls, the pouty girl marched up to the closest stranger: Charles.
The former professor felt a tiny hand pat his and inquisitively looked down at the girl. She seemed not at all fazed by the three strangers in her home. In fact, she seemed to love the change and even stared up at Logan curiously.
"Where do babies come from?" Charles bit his lip as Hank and Logan chuckled lowly.
"So - So how is school?" The girl shrugged.
"It's good. Want some tea?"
Charles grinned a little. As a boy, he loved pretending to pour tea, even though his parents considered it too effeminate and banned it.
Perhaps he could harmlessly amuse himself for a minute. They had some time, right? Besides, Charles probably needed to distract the girl until her brother came out.
He turned to Hank and Logan. "Why don't you two wait outside? Unless you'd like to wait for Peter."
They shrugged and went outside, and Charles smiled warmly at the the girl.
"I'd love to have tea."
He followed her to the living room, and she went upstairs to get her tea set. Five minutes later, she returned with pink and purple cups and saucers. They sat down on makeshift seats made of pillows and sat at a small coffee table.
"Sowy. Mommy doesn't like having stwange people in my woom. Is Peta gonna be okay?" Charles sipped his "tea" and nodded. "Is he in twouble?"
"Not at all, dear."
"Your hair's so long." She reached across the table and gingerly took a few strands of his hair. "It's like mommy's. Don't you want to cut it?"
"Getting older makes you lazier," Charles confessed. The girl pursed her lips, lost in her thoughts for a second.
"Is that why daddy left us?"
Charles shifted uncomfortably in his seat. He loved children, but he never enjoyed getting involved in familial affairs. His were not very grand, so he could understand a neglected child's pain all too much...
"I don't know why your father left. Perhaps your mother and father did not get along. Perhaps he is a fool. Regardless, any man willing to leave a daughter like you or a son like Peter is no man, my dear."
The girl looked ready to cry, but she still gave Charles a weak smile and a quick hug. He embraced her as gently as possible.
"You hug like mommy," the girl murmured, releasing him. "Like you're gonna lose somebody. Can I ask you another question, Mister..."
"Xavier." He could not stop grinning. Despite speaking so bluntly, she was awfully adorable. He shook her tiny hand. "Charles Xavier."
"Can I call you 'Charley'?"
"Of course."
"Did you love somebody who left?"
Her impolite question left him speechless and overwhelmed with memories, but he forced himself to smile again and answer briskly.
"Yes, love." His voice dropped to a soft whisper. Tears glistened in his deep blue eyes. "Yes, my dear, and I hope for your sake that you never loved like I loved."
The girl pouted and gave him another hug. "I'm sorry, Charley! You'll find someone else."
No, I wont. Charles nodded and patted her head. He saw Peter walking out the front door and gave the girl one last hug and a goodbye. Before he could reach the door, however, Mrs. Maximoff stopped him once more.
"Be careful with my son. Please."
"I swear nothing will happen to him," he promised, shaking her head. "It was lovely to meet you and your children, Mrs..."
"Maximoff. And you are..."
"Charles Xavier." She offered him some coffee, but he politely declined and left, thinking of the man who left.
"I am so sorry... I want you by my side... We want the same thing."
