Jack sighed. "No one in this town knows who Jack Frost is, huh…"
He had come to this random place called Arendelle, just to check it out. He flew around the entire place, tapping people on the shoulder (his finger went right through them), trying to make conversation, even yelling out loud "HEEEEEEEEEEEEEEYYYYYYYYY!" No one could see him, and it was a major bummer. No one believed in Jack Frost here, and it was killing him.
Staff in hand, he went up to the town's palace and landed (rather gracefully) onto this real fancy-looking balcony. He would admire it, but he was kind of pissed off at the moment.
He stood on the railing and yelled at the view in front of him. "THIS SUUCCKKSS! AAGGGH! WHY CAN'T ANYONE SEE ME?!"
He took a deep, angry breath and sat back down, but then he heard a voice.
"U-uh, who are you?"
Jack's eyes widened as he whirled around. Someone was talking to him.
He saw her.
"How in the world did you get up here?!"
She was talking to him. She looked pretty frightened, but she was definitely looking at him.
The boy jumped up in excitement, all smiles. "You can see me? Do you know who I am!?"
She flinched and frowned. "W-well I—what kind of question—you should answer me first! How'd you get past the guards?"
How could she see him if she didn't know—oh, never mind, that didn't matter at the moment! His spirits were lifted again.
He jumped up and did a backflip in the air. "No need to be scared!" He came closer to her, hovering, touching his nose with hers.
Obviously confused, her face turned red, and he grinned.
"My name's Jack Frost. Who are you?"
