Jack observed Anna and the man she was with talking to a group of rock trolls. It was difficult to discern anything over the commotion, but one thing was clear. The trolls clearly believed that the two were a couple. Just as clear, however, was that they weren't.
All of a sudden the commotion was hushed, and Jack could get his first clear look at Anna. Far more of her hair had turned the same color white as the streak she'd had since childhood. Jack thought about the day he saw that streak appear.
"Anna, slow down!" a young Elsa called out to her sister. With a small grunt she flung a shot of magic to catch her sister from falling. Instead of making the small hill intended, the burst of icy energy hit Anna in the forehead, and the small girl rolled to a stop in the snow, unconscious.
"Anna? Anna!" Elsa said. From his viewing point at the window, Jack gasped as a small streak of Anna's hair drained in color, turning white.
"Mama! Papa!"
The King and Queen rushed into the room and after taking in the scene, the entire family left the palace, toward the home of the rock trolls.
Jack sat looking over the scene and followed when the man -whom he now knew was called Kristoff- sped off on the reindeer with a shivering Anna in his arms. As they approached the palace, he flew ahead to find Elsa. He knew where she was from the Prince Hans' comments at the ice castle. As he flew through the dungeons he looked for any signs of distress from Elsa, but there was no cold wind, flurry, or icicle. Somehow though, he still felt uneasy.
When he finally found Elsa, she was lying on the floor of a cell, her hands encased in shackles. He knelt beside her and touched her face, waking her instantly.
"Jack?" she said, confused. She attempted to stand but tripped over one of the chains. Eyes widening, she realized where they were. Looking down at her hands slowly, she stepped over the chains binding her, straining to look out the window.
"Why did they bring me here?" she said, turning to Jack with a panicked look, "I'm a danger to Arendelle!" she cried out voice breaking. Just then, there were footsteps in the hall leading to her cell, and Prince Hans entered. The queen repeated herself to him, along with a plea for release.
"I'll try my best." He said as he exited.
"Elsa, are you alright? Anna is on her way, she should be here soon." Jack said placing a hand on Elsa's shoulder in an attempt to soothe her. She turned to him with fierce determination in her eyes.
"I have to get out of here." She said calmly, and closed her eyes. When Jack looked down at her bound hands, he saw that the metal was freezing. He looked back up at Elsa's face, her brow furrowed, a bit of her hair in her face. He placed his hand under her chin, startling her. And he kissed her.
It wasn't a passionate, heat of the moment kiss. It was the kiss of someone who is seeing true beauty, and wants to show their appreciation. It was light, and lasted only a moment.
When the moment ended, the shackles burst, shattering the glass behind them. Elsa looked at her hands, then at Jack. Before he could say anything, she leapt through the open window, and ran.
