Kristoff knew he would never forget the emotional turmoil he went through on that day when Anna turned to solid ice.
It started as and anxious niggle fluttering inside his chest as he watched her beautiful strawberry blonde hair slowly turn snow white.
It grew into a low hum of panic as she collapsed in his arms, death cold and shivering, while they stood under that archway surrounded by his family.
It worsened when Grandpabbie confirmed that there was nothing he could do to save her.
It turned into a desperate determination as he scooped her up onto Sven and galloped towards what he hoped would be her salvation.
It tore and shredded his heart as he watched her ushered through those heavy gates that slammed in his face, never to see her again.
It sunk into a pit of dread as he watched the storm build across the Fjord, solidifying his fears that Hans would not be enough to bring her back and enveloped him in terror as he and Sven raced to find her.
It snaked around him and suffocated him with fear as he struggled to see her through the raging storm.
It filled him with a glimmer of hope as he heard her call his name, and urged him to her as fast as he could. He would make it! He would save her!
And then it dissipated and transformed into utter horror as he watched her stumble away from him, towards a hulking form to his right.
Then, as he watched that last puff of air escape her lips, it nearly knocked him back with the agony of his failure, and threatened to engulf him as her sister sobbed over her frozen form.
It became a blissful elation that spread through his body as he witnessed the warmth flood through hers.
It soon twisted into an ugly rage, however, as he realised what Hans had done, but just as quickly he was filled with pride when, in all her feisty-pants glory, Anna punched him so hard in the face that he fell over board.
It made his heart do cartwheels as she looked at him over her sister's shoulder, her eyes filled with wonder and love.
By the time they had arrived back at the palace, told and retold the story of their adventure, Kristoff was emotionally exhausted, and pretty sure he was now ready to face anything in a stoic manner.
But nothing, absolutely nothing, could prepare him for the sheer unadulterated joy that shot through his body and made his fingers tingle as he gathered Anna into his arms and kissed her. This time knowing that he would never let her go.
