Xavier crossed the floor of Castle Arendelle, his wheelchair rolling across the floor, making small scraping sounds.
Elsa winced at the noise. She was informed that this… Xavier would have a strange contraption that she still couldn't identify. She squinted. It looked like a chair on wheels. A… She struggled to find a word for it. Wheels… Chair… A wheel..chair. Wheelchair.
"Elsa?" A voice penetrated her thoughts. She stood up straighter.
"Yes?" She asked. Her face flushed.
"Don't feel embarrassed, Elsa. I wouldn't have expected you to know what this is." He gestured to the wheels underneath him. "It's called a wheelchair. I'm paralyzed from the waist down."
"Paralyzed?" Elsa asked, her head turning slightly, her eyebrows going up.
"It means that I can't move my legs." He told her, patiently.
"Oh." She said, feeling her face go even redder. "I'm sorry, I didn't mean to stare." But Xavier was already shaking his head.
"I would stare too if I was seeing something I didn't understand. Especially since this is not in your own time"
"Yes, how did you get here?"
"That would be a very good question." Said a voice behind Xavier. Elsa glanced behind him and to her surprise, saw another strange man. He was very handsome, she thought to herself. He had on a long brown coat, and very ruffled brown hair.
Even more curious was a big blue box that stood behind him. On it read "Police Box."
"Who is this?" She asked Xavier.
"This is my friend, he's called the Doctor."
"The Doctor?" She frowned. "That's a strange name."
"Yes, well, if it wasn't for this man, I wouldn't be here." Xavier said, looking at Elsa seriously.
"I wouldn't say 'a man.'" The Doctor said.
"What would you call yourself, then?"
"If we told you, you wouldn't believe us."
"I'm sure that I could." Elsa said. Casually, she curled her fingers, and a small crystal appeared. The ground around her froze, and icy fractals reached just before Xavier's toes.
Xavier made no move to stop her, even though he knew he could. He didn't take much stock in controlling people's minds, unless he absolutely had to.
"I'm an alien." The Doctor said, rubbing the back of his head, nervously. "From Gallifrey. I'm a Time Lord."
"That isn't what we are here for." Xavier said, before Elsa could ask.
"I'm listening." She said. After all, she couldn't exactly refuse the note she had gotten a few days ago. It was entitled in Xavier's name. She hadn't been expecting this… Doctor person.
"Elsa." Xavier said, as though every word he was saying was important. It probably was, more than Elsa knew. "You have gifts. Gifts in Arendelle that aren't exactly…" He paused as if searching for a word. "typical."
Elsa nodded. The Doctor remained silent, though his eyes were on Elsa the whole time, as if gauging her response. She forced her gaze back to Xavier. "Yes." She said. "I'm very well aware."
"Since you know, you did put Arendelle into an eternal winter." The Doctor added, unessesarily.
Elsa turned a withering gaze on the Doctor. "If it was eternal, we would still be in a frost, wouldn't we be?" As if in response to her irritation, ice had widened its circumference around her. Xavier quickly took control of the situation.
"Elsa, I know you've wanted to control your powers for a long time, now." Xavier said.
Elsa looked at him, surprised. The ice ring stopped its outpour. "How did you find me, anyway?" Xavier sighed.
"The Doctor has seen what you can do, and he knew that he could contact me in events such as these."
Elsa looked at the Doctor again, and he smiled, raising a hand and wiggling his fingers in the most arrogant way possible. "Hello!"
"And what exactly do you do, since the Doctor contacted you?" Elsa turned her gaze back to Xavier. She rather liked the man. He was older, and had lost all of the hair on his head. He was amiable in large contrast to The Doctor, someone who irritated her immensely.
"Elsa? What's going on?" Elsa could have recognized that voice anywhere.
"Anna, not now." Elsa turned towards the window that Anna had hidden behind very well until that point in time. Elsa knew that she couldn't keep quiet very long.
"But-" That 'but' didn't get very far when Elsa thrust her arm out, freezing the window in place so that Anna couldn't open it.
Anna's freckled face pouted, and she walked away from the window, dejected. To Elsa's amusement however, she saw Olaf plodding behind Anna, his flurry of snow following him wherever he went. It was what kept him from melting in the new spring. He was grinning from ear to ear, if snowmen had ears. He could smile very wide if he wanted to. He bounced up and tugged on Anna's cloak, and Elsa could see Anna smiling at his attempt to cheer her up.
To Elsa's surprise, she found herself smiling. She flushed, embarrassed, knowing that both men had witnessed this scene with her sister. Xavier's face was unreadable, but patient, while The Doctor was smiling.
"You have a good relationship with your sister, I see?" Xavier asked.
"Yes." Elsa replied.
Xavier paused before continuing. "As I've said before, you have gifts. I think that if you were trained, you could control them so that your emotions couldn't get out of hand."
"Trained?" This piqued Elsa's interest. "What do you mean?" She ignored the fact that he had mentioned that her emotions could get out of hand. He hadn't said it witheringly. He had stated it as a fact. And maybe even something he could help her with.
"Yes." The man said. "We have a school, for children."
"I'm not a child." Elsa said, her face firm.
"Elsa, I didn't mean any offense. I am just used to having children in that facility. There are several adults there, as well. In fact, there is a woman named Jean, whom I think you would get along with very well."
"And why is that?' Elsa asked. She tried to sound irritated, but her question came out as a curious entreaty.
"She is, in every way, opposite of your power. We call her the Phoenix."
"Phoenix?" Elsa asked. "That bird is in fairy tales."
"So are you." Xavier said.
"What do you mean?" Elsa asked, her heart fluttering. "I'm as real as you are."
"That's not what many children would think. In fact, all of the children at the school would love to get to know you. Your power is that of legend."
Elsa's head pounded. "The only way that they would know is through you." She said. "I'm not a legend."
"Our time is in the future, Elsa. You're just a story to them, right now."
"How is that even possible?"
"It's the same reason that we managed to come here, Elsa. Trust me, it will all make sense in the end."
"You want me to come with you?" She asked, disbelieving. "And leave my sister? You must be out of your mind."
Xavier smiled at this, and as Elsa looked up at the Doctor, she could see that he was as well.
"What? You think this is funny? It's not." Elsa said, irritation rising in her.
"No, Elsa. I understand that this must be hard to accept."
"Accept? You're acting as if I don't have any kind of choice in this."
"Believe me Elsa, if I were to force you into anything, I would already have done so." Xavier told her. Elsa felt blood drain from her face.
"What do you mean?" She asked. Her voice became smaller. As queen, she never liked feeling like someone else had the hand in situations. Especially someone she didn't know. It must have been the effect from Hans's influence. How her sister had trusted him completely, but he had turned into one of the biggest criminals in Arendelle.
You're not the only one with gifts, Elsa.
Elsa gasped. "What was that?" She looked at The Doctor. "Did you hear that?"
The Doctor shrugged, nonchalantly. "I didn't."
Elsa looked at the man in the wheelchair accusingly. "Who are you?" Her voice rose in pitch.
"Elsa, in no way do I intend to threaten you." Xavier said. "I've seen what power can do to people. The difference between the truly good and evil people is how they use this power."
Elsa didn't answer. She didn't know what to say.
"I know you are confused, Elsa. Trust me, and I can help you."
"How can I trust you?"
"I know about the situation with Hans." Xavier said.
"What?" Elsa hissed. "That's private. You of all people should know not to invade people's minds." It was hard for her to process that fact, but that was the only thing she could think of that would have worked. If she could create ice though, this Xavier could infiltrate her very mind.
"Elsa, I do not look into memories. That is too private, and is none of my business. The Doctor was here when this all had happened. I did not influence or look into what is not meant for unfriendly eyes."
Elsa was shocked into silence again.
"If I go with you so I can control my power, who will rule in my place while I'm gone?"
"Are you forgetting your little sister? She can act as proxy for you."
Elsa considered this. She didn't want to leave her alone.
"When you come back, you will be a better ruler for Arendele." Xavier told her.
"Where in all of this," Elsa paused, "do you come in? How do you benefit?"
"I understand your suspicion, Elsa."
"With recent happenings, I've had problems with trusting strangers." The image of Hans's face burned into her mind.
"I can take you back whenever you like. I won't question, I won't try to convince you otherwise." Xavier said. Elsa looked into his eyes. She saw no guile there. Then again, that's what she saw in Hans.
She shook her head, distractedly, as if shaking off the man's power. When he had entered her mind earlier, she had felt a weight on her shoulders. Maybe that was the effect of his power. She felt no such feeling, now. He wasn't influencing her at all, just watching her expectantly.
If he wanted to be like Hans, he could have been.
But he wasn't. He was just like any teacher should have been. Willing to teach his students about essential things that would benefit her. He wasn't going to hurt her, or Anna, she realized.
She straightened her posture, folding her hands into each other like she had seen her mother do when she made a decision.
"I accept."
