Detective Kate Beckett's heart sank as she heard the sure sounds of the door being locked from the outside. Lowering her gun, she went over to the door and shoved her weight against it. It didn't budge. But that didn't stop her from trying again and again until Castle came over and stopped her.
"Whoa!" He said, wrapping his arms around her, holding her in place. Kate couldn't help but sag a little into the strength and warmth of his arms. "Ok?" He asked her, and she nodded. Castle let go of her and wandered to the back of the freezer. "Kate….?" He called. She looked up at him. "It's Jamal." Becket immediately came over. Jamal was frozen solid, so he'd obviously been in here a while. But that hadn't been the cause of death. Jamal had been shot through the head, just like his cousin, Amir. Beckett took in the sight, then turned away and walked back towards the front of the freezer. There had to be a way out of this! She heard Castle walk over to join her.
"How cold do you think it is in here?" Castle asked, already shivering.
"One below zero." She told him, the cold already starting to steep into her bones. It wouldn't be long until the hypothermia set in. Kate looked around, desperately looking for a way out. She examined the door, then drew out her gun and fired several shots at where she figured the lock was.
"Whoa, whoa, whoa!" Castle cried, ducking down to avoid any ricochets. Kate turned towards him.
"No one knows we're here Castle. We have to get out!" Castle nodded.
"But that," he said, walking over to her. "Is just going to get us killed." Kate couldn't help but see his logic and put her gun away.
"This isn't good Castle." She said.
"No, it's not. Not at all"
"I could really use a silver lining right about now."
"I really wish I had one." Castle said regretfully. Kate sighed and sat down. She shivered, running her hands up and down her frozen arms. Castle just plopped himself down on the floor next to her.
"Um, I have an idea. If we sit close together, maybe we won't end up being found as human popsicles" Castle said, smirking.
Kate just glared at him but shifted so she was between his legs. She couldn't help but feel an immediate sense of warmth. They just sat there, neither knowing how much time had passed. Minutes, hours, days. Kate eventually lost all feeling in her body and Castle's body became as cold as Kate's, offering no source of warmth. Kate grew progressively more and more tired, until her eyelids grew heavy.
"C-c-castle, I w-want you to k-know that i-if w-we don't make it, I-i want y-you to k-know th-that I lo-" Kate stopped in the middle as her head lolled to the side.
Kate, Kate!" Castle tried call her, trying to hit her but it was no use as his arms were frozen and he could not move. A feeling of absolute dread rose in his chest as he could not see her chest move. She really did look terrible. Her skin was deathly pale, there was small icicles on her eyelashes and her lips were faintly blue. Worst of all, he wanted to know what he had been about to say. Who did she love?
After having sat there for ages with an unmoving Kate in his arms, Castle lost the battle with his eyes and they slid shut, welcoming him into the dark abyss where there was no cold.
